pfSense VPN tunnel traffic. Site A to Site B working, but nothing from Site B can get to Site A.
I have an IPSEC VPN tunnel configured between Site A and Site B. The tunnel is up and functioning fine. I am able to connect from Site A to Site B fine and interact with the mainframe software fine with a telnet connection. However the Printer at Site A is not being communicated with from Site B when inside of the mainframe connection (it has been working fine for several years until the firewall died and I just replaced with a pfSense firewall).
I have an IPSEC firewall rule for Source of any and Destination of any (Source *, Destination *) and that seems to be what allowed the tunnel to come up to begin with.
I am using pfSense and need to figure out what I need to do in order to get this working. From Site B, the client has tried telnetting back to port 80 to the Site A local lan printer IP and it's not working. Telnet from site A which is the local network for the printer on port 80 works fine.
It's probably something to do with NAT but I don't want to mess things up!
The difference is mostly just conneted to the routing.
So the side, where you created the VPN tunnel may have got a route from A to B, but you have to make sure, that there is also a route on the other end which points from B to A. So possibly an additional configuration step on the remote side.
