Additional IPs wont work

[broken egret]

So basically I have everything set up, and everything is working fine except additional IPs.
I have default IPv4 of a machine and I have bought additional IPs so that I could use default game ports for different game servers. Like csgos 27015 port.

Problem arises when I assign an IP that isnt machines default. Those additional IPs dont work for some reason even tho I have set up additional ips properly in netplan since Im using ubuntu.
It somehow doesnt detect that additional IPs. For example. I create csgo server and I put it on second IP, in the console of the game still registers the default machines IP.

Does anyone know how can I fix this ?

Please explain the issue you're experiencing in as much detail as possible. Preferably with error messages in a text format or paste link to logs. Nobody can assist you without information that helps to understand the issue. Help us help you. Messages such as "doesn't work" or "i need help" will most likely be ignored.

Go into the egg and turn on the force outgoing IP address option for the egg, then restart your csgo server

Now it does register it in console. But still no luck, I still cant connect to the server

[midnight veldt]

Make sure you can ping your additional IPs

Is this OVH? If so, do you have the firewall enabled for those IPs ?

It is OVH as for the firewall I know they have some game thing etc.. I havent touch any of that. Linux ufw is enabled tho

[midnight veldt]

If the game firewall is on for that IP (It may be by default) then you won't be able to connect though it until you either configure it, or disable it

[broken egret]

So its like this, default as it came

[midnight veldt]

Yeah, either configure the OVH firewall by adding your games ports in there, or disable it

[broken egret]

alright I will check it now

I just wanted to say thank you for helping me. I can confirm that was the problem.

I also own some servers at hetzner and there wasnt any issues with it after ticking "force outgoing IP address"

[midnight veldt]

No problem.
Yeah the OVH game firewall is very restrictive and will block all incoming UDP traffic if you don't add rules to allow it. Great for a layer of DDoS protection, but catches a lot of people when they don't realize it's there or how it works

[broken egret]

That is true, thanks once more. If I can repay somehow just say
