@waxen scroll Why is PFSense for noobs, just curious?

little schooner Sep 11, 2020, 5:16 PM

#

@waxen scroll to save myself time and headache while juggling two positions and two classes, the easy ways are very desirable

#

But it started working with promiscuous mode so I don't need to use it now 😄

peak cloak Sep 11, 2020, 5:25 PM

#

@signal mantle you can do everything in the GUI plus it does some stuff automatically for you

waxen scroll Sep 11, 2020, 5:31 PM

#

you dont want that on BTW

#

last i recall it sends every VMs packet to every vm

little schooner Sep 11, 2020, 6:25 PM

#

@waxen scroll I read that yeah. Well, this is for an isolated lab network but your right, I should have like a router-vm in it so I don't have to enable it

#

@waxen scroll only now did I finally correctly imagine what you told me.... And it makes so much sense

#

So I will start incorporating it and play with iptables first

#

Earlier in the morning I was a little confused

#

I don't want to leave promiscuous on

#

It shouldn't even be that hard

rocky badge Sep 11, 2020, 7:30 PM

#

yeah 😦

waxen scroll Sep 11, 2020, 7:34 PM

#

@little schooner so you have two vswitches.... one for public DMZ space one for private space. Your router gets interfaces in both. Your router will act as GW for the private vswitch. Your router will NAT for all devices in the private zone.

#

Because its default GW your VPN can access that zone and optionally the internet

little schooner Sep 11, 2020, 7:41 PM

#

@waxen scroll wait, so why is it that datacenters dont use that much security when they are inside the datacenter's lan? all the security is on the outside only?

#

@waxen scroll and thanks for the description

waxen scroll Sep 11, 2020, 7:42 PM

#

they do

little schooner Sep 11, 2020, 7:42 PM

#

@waxen scroll oh, i thought you said that they didn't have as much firewall control or rules

waxen scroll Sep 11, 2020, 7:42 PM

#

im only telling you how to do it with a single server and a basic internet connection

little schooner Sep 11, 2020, 7:42 PM

#

oh no, i am referencing an older conversation we had

#

not related to my current case

waxen scroll Sep 11, 2020, 7:43 PM

#

most people split the datacenter into zones.... Production, Dev, QA, whatever else.... each zone uses a firewall as the gateway (at some point)

#

modern designs actually now do device to device firewalling

#

no zones, devices are all firewalled

little schooner Sep 11, 2020, 7:44 PM

#

hm. I see.

waxen scroll Sep 11, 2020, 7:45 PM

#

zone based means that if an attacker gets into a dev device, they can go sideways to other dev devices but might not be able to jump to prod

little schooner Sep 11, 2020, 7:45 PM

#

and dev is never supposed to reach prod under any circumstances anyway, right?

#

they would have to jump onto a prod dev

#

what if dev needed to make connection to prod?

#

for like 2 minutes

waxen scroll Sep 11, 2020, 7:46 PM

#

no, you can do whatever you want.... but its best not to let dev and prod talk if you can help it. people might abuse that, especially if your company bills for resources.... someone might decide its cheaper to host in dev and let it talk to prod

little schooner Sep 11, 2020, 7:47 PM

#

interesting

waxen scroll Sep 11, 2020, 7:50 PM

#

theres no right way to do it. its whatever the company decides makes sense for their usage

#

some might choose to block internet to a zone until you open a request for specific servers, some might not

#

its complicated

#

@clear igloo it makes me lol how reddit is all "omg infosec isnt an entry level job" and then i look how it actually is

#

🤔

#

3/4ths of it are people who know I PUT RULE HERE. 1/4th is "we want the firewall to BGP because... blah"

need router what buy

little schooner Sep 11, 2020, 10:28 PM

#

@waxen scroll I couldn't get it to work. They do not require internet access, but it's that it still was having trouble reaching an IP address part of the real network assigned to a VirtualBox VM that lives inside a Ubuntu VM in esxi.

I thought it was working initially with iptables because I was able to ping all the way down to that. But the nested vms still did not respond.

I should draw out what I'm saying. I don't think I'm explaining it well lol

#

I had to undo all the changes quickly since I ran out of time testing

Oof

little schooner Sep 11, 2020, 11:09 PM

#

@waxen scroll i really just slapped this together but, why, even with an iptables VM, does the ping not go through ubuntu > virtualbox > the centos ip?

#

📎 unknown.png

#

is it because the Ubuntu vm sees the packet isn't for itself and doesn't bother processing it?

peak cloak Sep 11, 2020, 11:10 PM

#

why not use a hypervisor instead of ubuntu?

little schooner Sep 11, 2020, 11:11 PM

#

@peak cloak I wanted to create a self-contained fat vm with other vms inside of it

#

and then they can operate in their own private network within this vm

peak cloak Sep 11, 2020, 11:11 PM

#

hmm ok

little schooner Sep 11, 2020, 11:12 PM

#

but I am starting to think that because the ping request is for a different IP than what Ubuntu has, it doesn't bother to take the ping request into the nested vm or something

#

but with promiscuous on, it starts to work

#

which isn't the ideal config

#

@waxen scroll the nested VMs should use a virtualbox NAT adapter instead?

unborn sluice Sep 11, 2020, 11:14 PM

#

pog

hollow marlin Sep 12, 2020, 2:15 AM

#

@little schooner I would assume the issue you are running into is due to the subnet and it only listening for its own MAC. Both Ubuntu and VM are in the same subnet and Ubuntu will not switch the frame to the VM. Its why when you go promiscuous (bridging) the connection works

#

I don't have experience with nested VMs but it looks to me to be the issue. IPtables is just for routing and you'll need to slap your nested VMs in their own subnet and your preferred flavor of routing.

little schooner Sep 12, 2020, 4:41 AM

#

@hollow marlin makes sense

#

Yeah it was driving me crazy a little bit 😅

#

It's fine for now it's only a temporary setup and any outgoing connection are all automatically blocked too

#

The issue tho is the insane amount of broadcast traffic when stuff like rdp sessions are running in that env

#

At least it doesn't show issues at the moment with 20 of them

#

So I can just move on from it

Hey, I have a tplink archer c50 ac1200 router. I use my Virgin Media Superhub 3 as a modem. Recently, there have been cut outs that only last for a few seconds but have become very annoying while gaming, because I get kicked out of the game. Is it my modem or my router?

green crest Sep 12, 2020, 9:05 PM

#

I am no expert in networking, but is the computer connected through wired means or wireless? If it is wireless, maybe you are having a weak signal?

wary sequoia Sep 12, 2020, 9:11 PM

#

I am no expert in networking, but is the computer connected through wired means or wireless? If it is wireless, maybe you are having a weak signal?
@green crest Not a computer, it’s an every device thing. We use wireless.

#

And by every device I mean literally every device. Alexas go out, Netflix streams turn choppy, Range Extenders cut out too.

green crest Sep 12, 2020, 9:13 PM

#

Maybe your router has issues

wary sequoia Sep 12, 2020, 9:13 PM

#

This same issue happened when we used the ISP provided router/modem, but the cut lasted for 10 minutes instead of five seconds.

green crest Sep 12, 2020, 9:13 PM

#

Only way to know is checking if the modem is working fine

wary sequoia Sep 12, 2020, 9:13 PM

#

I’m gonna take a guess and say that his modem sucks ass.

green crest Sep 12, 2020, 9:13 PM

#

If the ISP router still had the same issue, that it is probably the modem

wary sequoia Sep 12, 2020, 9:14 PM

#

How would we go about fixing this? Would we have to swap ISP or get a replacement router?

#

Router/modem i mean.

green crest Sep 12, 2020, 9:16 PM

#

Wait, is the Virgin Media Superhub 3 provided by the ISP?

wary sequoia Sep 12, 2020, 9:16 PM

#

Yes. the TP LINK ARCHER C50 is what the bought ourselves.

green crest Sep 12, 2020, 9:17 PM

#

okay, so contact your ISP to see if they have a replacement or an upgrade for it

wary sequoia Sep 12, 2020, 9:18 PM

#

There’s no upgrade, the Superhub 3 has been out for a long while. We’ve also asked for a replacement because it’s faulty, but they didn’t acknowledge it. Seems like this issue happens with a whole bunch of other Virgin Media customers, and the company doesn’t want to help the issue with them either. Unfortunately in my area the only ISP that provides speeds over like 30mbps is Virgin, so I’m stuck with them.

#

Their customer support is bad, and replacement routers go for £50. We’ve been stuck with a £6000 bill for a new roof so we really don’t want to have to spend any more money than we have to.

green crest Sep 12, 2020, 9:23 PM

#

Maybe the cable that is attached to the modem has issues?

wary sequoia Sep 12, 2020, 9:23 PM

#

I don’t think so, it’s the cable that came with the new router.

green crest Sep 12, 2020, 9:25 PM

no, the moca cable

The cable that connects to the little socket in the wall?

green crest Sep 12, 2020, 9:29 PM

#

yes

wary sequoia Sep 12, 2020, 9:29 PM

#

Is it likely that that’s the problem?

Maybe, I had a similar problem like yours where my moca cable was damaged and killed off all internet in my house. I had to change out cables and the modem worked

pair the 5g to a device(laptop or desktop) have the device act as a gateway(share the connection) hook the device into a router. the device paired with the 5g would be pretty much open to the internet though. behind what ever nat the 5g celluar uses.

@rocky badge BY, E7, E9 platforms do port isolation by default. However that is only per blade. If the VLAN is spread among multiple blades you will be seeing those MACs. They'd need to use private VLANs or MetroE upstream.

Can anyone help me figure out why this happens because I am trying to get at least 300 mbps because it is a requirement for my work.

Each NVR handles around 1000 cameras

There's 3 of them

its what 90% of companies use for documentation. he should learn it

easier to let systems team admin it and you just provide content

@little schooner all of your documentation should be versioned, approved, and audited as well.

sharepoint is free for schools at the most basic plan im pretty sure

#

with onedrive and office apps

waxen scroll Sep 14, 2020, 11:31 PM

sharepoint is also free if your companies finance people have a backbone. like if you have an azure agreement usually you can bully MS into free O365 if you're a larger customer

#

@rocky badge your #1 question you need to ask daily when in IT

#

what do I have to do in order to not support anything anymore?

#

your goal is to get max pay while doing as little support as possible

hollow marlin Sep 14, 2020, 11:55 PM

#

Supporting all kinds of things was cool at first until you have real stuff to do. Is it networking? No, open a ticket with IT

waxen scroll Sep 14, 2020, 11:57 PM

#

yep

#

and its possible to still be technical and do no support

#

i dont consider tier 3+ escalation support

#

as long as its not every week

#

@hollow marlin im completely unimpressed by equipment and datacenters at this point

#

give me the CLI/GUI whatever and we're done

someone else can rack it

little schooner Sep 15, 2020, 2:09 AM

@waxen scroll that's what I got at home. But it isn't rack mountable and it's a tower. I really should replace it

waxen scroll Sep 15, 2020, 2:10 AM

Why would you nuke your file performance with a nas

Local storage is king

Let your crappy devices take the hit, not your main pc

@little schooner plus you save power bills depending on the situation

little schooner Sep 15, 2020, 2:21 AM

@waxen scroll I was thinking at least an 8 core amd mini pc with 10g port and running on power saver mode

#

I can manage to pull 10gbps over it still. That's the ideal scenario

#

Thing is that companies love charging a lot more for sff and even then they use terrible cpus in them

The logic is baffling but from business perspective it makes sense.... For them only

But it was a layer 8 issue this time

waxen scroll Sep 15, 2020, 4:18 PM

the room is for network equipment discussion only, per the subject, so if you start talking layer 7 it better be because you have an issue with a riverbed wan accelerator and not your PHP script for TikTok2

I just got a juniper EX2200 PoE switch. I'm trying to connect to the serial console. I have a USB to RS232 DB9 serial adapter. The switch has an RJ45 jack for serial, is there a specific apadapter I need? Or would the startech one where you set the pinout yourself be best?

tame carbon Sep 15, 2020, 4:23 PM

#

I bought a generic 'cisco compatible' USB to RJ45 (UART) cable

but the pinout is standard

if you have db9 to rj45, just try it out

worst case, you get some garbled symbols

@tame carbon Amazon definetly sells non standard pinouts.
