I have a client that has a SBS and I just switched their Qwest connection to Comcast yesterday. I updated DNS on GoDaddy to point the updated DNS records to point to the new Comcast Static IP (which is actually the IP of the gateway) and if you try and access https://remote.domain.com externally RWW works just fine. However if you're on the local network and try to use the same address it acts like it's going to work (prompted with invalid certificate/continue screen) but after selecting continue it goes to the interface (192.168.55.1) of the Comcast gateway instead of the server 192.168.55.100.
It's acting like there is some DNS record locally that points remote to the gateway instead of the server, but I'm not seeing anything. Its got to be something easy...I'm just not seeing it
Network setup = Comcast SMC -->16 port switch --->SBS
