I am being baffled by this issue and need some help.
Here is the scenario.
Time Warner Cable High Speed has a Ubee modem. Verified today that it is in passthrough mode with no ports being blocked.
Then a Netgear FVS318N business class router.
Thru that is a SBS 2011 server. I have verified the IP address of the server and it's rdp port, which is the default 3389.
On the router I have the server and the route mapped so that from the outside with the public IP, it should be able to port right through.
I can RDP to the server from inside with no problem.
On the server or the network, I can go to canyouseeme.org and put in the port of 3389 and it says it is unresponsive.
On the server, I have tried connecting with the firewall totally off and have tried it with the firewall on, with the port open.
Just crazy here. Don't know what else it could be.
I would be having trouble with the network if there were another router in place. The SBS 2011 is currently just serving files. DHCP and DNS are being done on the router.
I have another PC in the mix using RDP port 23389 and it also can not be reached. Have a camera system also that can't be reached. Router is maybe 6 months old.
