pfSense blackholing traffic from VPN
-
Not sure if this is the right section for this but it's the best place I could find, so here goes...
So I'm seeing some odd behavior on one of my pfSense boxes and I can't for the life of me figure out why. I have a pfSense box that terminates all of my VPN connections, and then connects to a point-to-point back to the main firewall that connects back into the rest of the local network. This VPN router does not have the firewall enabled so that's ruled out as a potential issue.
The behavior that I'm seeing is that hosts on the remote end of one of the IPSec VPNs (an Azure VM) are unable to access the local network. A packet capture shows packets coming from the remote hosts entering the IPsec interface but it doesn't exit out of the point-to-point interface to get to the local network, so it appears that traffic is just getting black-holed by the VPN router.
I've checked routing and the routes are all correct (I'm using OSPF between the VPN router and the main firewall, and BGP over the VPN links). Does anyone have any ideas as to what could be going on?
