Remote Desktop connection through modem to firewall
This used to work. We use Remote Desktop Connection to connect to our public IP address including a port number (50.n.n.33:51115) to a specific computers port 3389. The port forwarding rules are on our firewall device. We can’t get the Comcast modem to pass the 51115 port number thru to the firewall.
With the modem in non-bridge mode, its WAN IP is not our assigned static IP. Using the WAN iP with RDC fails with the target computer not being found. Incidentally pinging the static IP is not found. Pinging the WAN IP works.
As a test, I plugged a computer into the modem LAN port and using the firewalls WAN IP was able to remote into the target PC, so the forwarding rules on the firewall are working.
this morning I had bridge mode enabled on the modem. Trying to RDC to our static IP still doesn’t work. RDC to the IP the modem reports as the WAN IP doesn’t work. RDC to the firewalls WAN IP, which now seems to be coming from Comcast, doesn’t work. The firewall WAN IP is set to be set by DHCP.
Help! Any suggestions?
Do I need to set the firewall WAN IP to the static IP assigned to us by Comcast? Our firewall is using pfSense.
