pfsense through IPsec routing
I have 3 sites.
Site A: using pfsense with 2.4.4 version
Site B: Peplink
Site C: Peplink
In Site A: I have one server. Pfsense has IPsec connection to Site B Peplink
In Site B: multiple workstations. This peplink connects to Site A Pfsense through IPsec. Also connects to Site C peplink with SpeedFusion (implementation of vpn)
In Site C: I have one server. This peplink connects to the peplink in site B with SpeedFusion.
If I ping server at Site C from Site A, there is no problem. Server A > pfsense A > peplink B > peplink C > server C. Works fine.
If I pink server A from Site C, I can't reach to it. Server C > Peplink C > Peplink B > pfsense A > Server A. Doesn't work.
Any clue what I need to setup here so that this works?
