Comcast SMC Cable Router Management
Hi All,
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.

Yes, I tried Telnet with no success. I did not see any settings in the router to enable/disable http management.
Yes I am using the static (public) ip when I am out of the office.
I cannot use a port forward in this situation because there is a firewall between the SMC router and the local network. Actually the reason I need to get to the SMC from the internet is so I can access the firewall.
Thanks for your help.

What make and model is the router? You mention SMC, but is there more informaton available?

Its the standard SMC router that Comcast uses for there business customers. I believe it something like an 8014. I am not at that location right now, so I can't look at it.
ASKER
I already check with SMC's website and could not find any information on outside management. They tell you how to get to it from the inside.
Sorry cannot help further, I am not familiar with the units and as you say, very little documentation available on the 8014's
For the record; not all routers have external management capabilities that a user can access. Seems to me this unit is a combined modem/router? If so the connection IP may be the External/ISP's gateway address rather than the assigned IP.

Thanks for trying. I know that Comcast can manage the unit from the outside, I just don't know what they use to do it.. Thanks again.
As mentioned they may use the Gateway address. You will see it in the external configuration of the router.
You may need to open the proper ports on the router to except traffic coming from the outside. This is not recommended for obvious security reasons.

Thanks for the comment, but you don't need to open a port to manage the router for the WAN IP address. I would only need to open a port if I was going to access a computer or resource on the network behind the router. The routers are not very soficticate. Thanks
Alternatively: If you know what ports need to be opened to accomplish this, please let me know.

scottchtc, Did you ever get this riddle solved? I've got the same unit, it is running a telnet daemon and nmap shows the telnet port open, however, the web interface username and password do not work. I'm assuming that comcast has a username and password combo dedicated to the telnet server for access.
ASKER
No I didn't. I figured someone out there would know the anwser, but I guess it is a well guarded secrete.

You were both correct. I split the points, but awarded RTM_TSI a few more because his anwser was more detailed and he gave a work around solution. Thanks to you both.
Does the router have the capability to enable remote Http management? It is usually disabled by default. I also assume you are connecting to it using the external/public IP, rather than the same local/LAN IP.
Another option is to set up remote access using port forwarding and remote desktop to a PC on the LAN. From there you should be able to access the router using the LAN IP.
