I am a student trying to set pfSense to access the internet in front of a local router and I am struggling to get passed beyond pfSense. I suspect it is an issue with NAT.
The switches are acting as hubs passing traffic on. The Debian can ping up to the LAN interface of pfSense. The WAN is facing the internet, I have also tried to put a router connected to that WAN (R2), bouncing traffic back instead of internet with no luck, same result.
All interfaces are allowing ICMP and TCP any any. Also, for pfSense to send traffic back to Debian I need a Gateway in the LAN interface and a Route so it can go through R1.
pfSense WAN interface has connectivity, either to R2 or Internet.
I am not sure what I have to do to accomplish this but I would be really grateful for any hint.
Thank you for your time.
