Routing: Site A via VPN through Site B to Site C
I've got the following situation:
Site A (bintec Router - 192.168.178.0/24) has a VPN-Connection to Site B (bintec Router too - 172.16.0.0/16).
Site B has also a VPN-Connection to Site C (pfSense 2.3.2-RELEASE-p1 - 172.25.0.0/16).
I would like to access Site C from Site A.
The configuration (routing) in the router on Site A/B is correct.
bintec told me, that I've to configure route backwards on Site C.
Could someone help me, how to do it?
I found a lot of How-Tos regarding this topic, but they all created new interfaces, where I don't know a possiblity how to do it with the actual firmware.
Thanks a lot and kind regards,
on site-A you need a route for 172.25.0.0 with gateway:site_b_tunnel_address_X
on site-C you need a route for 192.168.178.0 with gateway: site_b_tunnel_address_Y
Site A is configured correctly.
My problem is, that I dont know how to configure the specific routing in the pfSense. Could someone tell me how to do this?
Thanks a lot.
This depends on your VPN setup. If you're running a site to site server or the client on site C add 192.168.178.0/24 to "IPv4 Remote networks".
it's a site to site connection.
But I don't know how respectivly where to add the configuration.
In VPN=>Tunnel=>Phase2 I can change the remote network, but not add an additional.
Under System=>Routing => Static Routes, I could add a route, but can only select LAN or WAN as gateway, not VPN.
Excuse my dumb questions, but it's my first time with pfSense.
Thanks a lot.
So it's an IPSec VPN. You should have mentioned this.
I'm not familiar with IPSec on pfSense, but there is a special topic in this forum: https://forum.pfsense.org/index.php?board=16.0
