LAN IP not seen over tunnel
I've setup a GRE tunnel over 2 locations with as GRE subnet 10.0.0.17/30.
Over that tunnel I'm setting a BGP session to announce the LAN subnets from both sides.
Side 1 - 192.168.2.0/24
Side 2 - 192.168.10.0/24
That is both working, what I do not get however is why when I do a packet capture, that when I ping an IP from 192.168.10.0/24 from side 1, I see the icmp requests coming from 10.0.0.17 instead of 192.168.2.0/24.
I'm doing exactly the same on a Fortigate and a Mikrotik but there when I ping an IP from side 2 in a capture I can see the IP from side 1 doing the icmp requests.
Now I'm not used to pfsense and I might be missing something but can't find what I would be missing then.
Problem here is that our VOIP gateway is blocking the GRE subnet since it expects getting a request from the LAN subnet of side 2.
check you outbound NAT if it configured correctly
