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!
