Azure - OpenVPN Remote access tunnel - NAT when try to reach other azure VM in the same vnet
I have a pfsense on azure and I have setup a remote access OpenVPN connection. We don't have any problems to connect to this endpoint. When I connect to that openvpn connection and try to reach other azure VM in the same vnet, the pfsense VM NATs the traffic
We have the same configuration in AWS and the pfsense VM doesn't NATs the traffic.
There is some way to avoid that the pfsense NATs the traffic?
Firewall > Outbound NAT
Make a NO NAT rule for the sources and destinations you do NOT want to NAT.
You will need to tell Azure to route the traffic for the OpenVPN tunnel network to pfSense.
Your advice has worked very well.
