Hi, I am Currently working on an Azure Networking Setup where a Official Pfsense+ Image Should be Used as Gateway to the Internet. The Current Problem that im Facing is that VMs that i connect into a Subnet where there is a Default route to the Pfsense Firewall dont have Access to the Internet. I Activated it Forwarding on the Nic of the Firewall. Does Anybody have Experience Regarding this kind of setup.

I currently can't see settings of Pfsense but do you have outgoing rules for internet traffic + outbound NAT?

#

I allowed all outbound as well as all inbound traffic int he Pfsense configuration

#

ok I see then I guess you have a rule like s:any, d:any and port:any? Check with traceroute where the connection halts

I Solved the Problem, Behind the Pfsense is some sort of Azure Service Witch prevents icmp Traffic, DNS... sems to Work fine

Thanks for your time
