I have a Comcast SMC Business cable router. I need to be able to manage this router from the internet. I have a static IP address and I am able to get into the management interface from the inside network using the local LAN ip address with no problem. When I am out of the office, I need to access the mamngement interface to change some settings and I cannot. I have searched high and low on the internet and it seems that Comcast is keeping this a well guarded secrete. I have tried to access it using port 80, 88, 8888, 8080, 8181 and https (443) but no dice. I know Comcast can access it when ever I call for trouble-shooting. Any help would be greatly apprciated. Other routers (Linksys, D-Link, Ect....) I have no problem accessing from the outside.
Thanks in advance.
