Motorola SBG6580 Portforwarding doesn't work

iineviidable · Mar 24, 2014

I've tried to portforward with this modem/router and it worked a few months ago.
But now i do it the same way but now it won't work.

Done right with a static ip and everything.

And i've done dmz but seriously, nothing works.

I think you need to copy the Internal Start/End ports to external as well.

Are you sure you're not on a CG-NAT connection?

Image with IP removed - SS

I've tried it like that with my internal and external ip but last time i had it working i only did the first internal and it forwarded fine.

And what do you mean by CG-NAT?

Someone Somewhere · Mar 24, 2014

Nope, what I mean is this:

192.168.0.24 27000-27050 0.0.0.0 27000-27050 Both

Carrier-Grade Network Address Translation. You share your external IP with a pile of other people, which reduces the number of IPs the ISP needs to buy. But breaks anything relying on inbound traffic.

Check whether the IP address reported by your router is the same as the address reported by Google.

Someone Somewhere :

Sorry I work weird hours.
How would i go about seeing my ip through my router page?
I dont see it in any of the menus.

I don't have any Motorola routers to test here, sorry.

You may be able to find it in the logs when it gets a DHCP connection. Should be somewhere under Status, too.

Found that. Not sure what this means but doesnt look good.

Someone Somewhere · Mar 25, 2014

I think that means the cable modem doesn't have a webpage you can access. Not a major issue.

It might be somewhere in the event logs, particularly if it's been rebooted recently.

Someone Somewhere :

I just rebooted it and checked and all i'm getting is something that says "Error (4) Missing BP Configuration Setting TLV Type: (mac address here.)"

Thanks for all the replied by the way.

Hmm.

Can you run a traceroute to somewhere? If it has a line with 10.x.x.x in it, you're on a CG-NAT connection.

iineviidable · Mar 25, 2014

Someone Somewhere :

It started and went through 10 and on 11 and 12 it failed. I did it to Google's IP.

Quick edit: Did it to a different ip and it says traceroute to (74.125.224.72) from (66.168.xxx.xx). And it completed. Same IP as google see's if that is the one you are talking about

What was the second line?

Who's your ISP?

iineviidable · Mar 25, 2014

Someone Somewhere :

Second line was "01 10.228.0.1 10 ms 10 ms 10 ms." Plus some more that were similar after that.
My ISP is Charter. I've tried getting help from them but since we didn't get it from them they won't help.

Someone Somewhere · Mar 25, 2014

Yup, unfortunately you're probably on a Carrier-Grade NAT connection. This means that they can share one (increasingly scarce) IPv4 address across ~10 customers.

Unfortunately, there's not a lot you can do aside from trying to request a public IP.

iineviidable · Mar 25, 2014

Someone Somewhere :

And unfortunately Charter has pretty awful customer service, so this will be interesting.
Thanks for your help, you've been fantastic.
