I am learning networking & pfsense and really enjoying it. I am working on a practical assignment but I have hit a minor stumbling block.
The assignment is to setup 3 networks in our lab. We then need to setup a simple IPSec VPN tunnel between site A <-> site B and site B <-> site C. Then the various sites need to communicate with which other.
I have configured the site A <-> site B and site B <-> site C VPN tunnels. The firewalls all allow ICMP traffic to pass through the firewall. However site A is unable to ping site c via site B. I understand this is an issue some sort of routing issue. In this lab example, do I need to add a static route on the WAN interface of site A to gateway at Site B to communicate with site C network 10.0.0.0/16?
