have a database that uses a login web client on a SBS2012
I open the port in the firewall for this web client and also made a passthrough on our Linksys router
the port is 245
we also have a passthrought to the SBS server for port 443, this works fine
we also have a passthrough to a NVR (192.168.1.33) on port 8100, this works fine
my problem is port 245
if I use www.canyousee.me.org
port 245 is not responding and all the other ports are open and test fine
We use a Comcast ISP, they do have a router here as well but this router is in bridge mode, I called Comcast support and they tell me our linksys is in charge of routing and that their router is in modem mode
I also called Linksys support and they double checked my passthroughs and say things are configured correctly but port 245 is not responding.
Could it be the web client is not working so the test I'm doing at canyouseeme.org is responding with "I cannot see port 245?"
