We have an office shared by two companies. I have watchguard XTM 26 for our company to be the internet gateway. We are attempting to connect to the other company's network in order to share a printer. Our network(say Company A) is on the 192.168.30.0/24 network and their network (say Comapny B) is at 192.168.20.0/24. I have Port 0 untrusted port setup for our internet connection. Port 1 is for our trusted 30.0 network. I have setup port 2 as optional with a 192.168.20.253 address and is going to company 'B's network switch. I can successfully ping the printer address (192.168.20.101) directly from the Watchguard, but can not get any client stations on the Company A network to get a successful ping to the printer.
I added "Any" policies to and from that optional port to our Compnay A network, but still no luck. I can see the log entries for successful sending of the ping, but nothing coming back in. I thought it may be that their (Company B) network not having any routes setup, but then why would the watchguard pings work and not the client stations?
Is it still a policy issue?
