So, I'm trying to port forward on this modem/router combo and everything I've tried just isn't working. I need to forward port 8080 so that my father-in-law can access my ebook server on his tablet from home. I set my local IP to 192.168.0.3 which is the pc that's running the server and set both start and end ports to 8080. I set extenal IP to 0.0.0.0 and both start and end ports to 8080. It IS enabled, yet every time I check online to see if the port is open, it just times out. Any help in this matter would be GREATLY appreciated!
Solved! Go to Solution.
I would set the dhcp start for 192.168.0.100 and put the server on 192.168.0.99, set that IP to do port 8080 TCP&UDP
do not use 192.168.0.2 to 0.10 for anything
The external IP should be the public IP and would end up being lets say 18.104.22.168:8080 to get in from the outside world and of course 192.168.0.99:8080 from your local lan
The 6580 is an all in one and may never work right, It's also an obsolete IPv4 modem no longer supported, TWC was throwing theirs out last year....
As MsRaye said before, the SBG6580 does not support IPv6 correctly. It also does not perform well with TWC's use of expanded channel assignments for internet service mixed in with encrypted digital TV. If you are in a larger urban area with more than 16 internet DS channels, it's time to upgrade to a newer modem like the Motorola MB7420.
