Comcast blocking all incoming ports?

[Silverskull]

Alright, so recently I've noticed that I haven't been able to access anything within my home network from outside... and yes, I have forwarded the ports. For example, port 22 is forwarded to my server, and I used to be able to SSH into it. This isn't just one port though, it's all of them... so could this be Comcast's doing? As far as I can tell, nothing's changed on my router. Has anyone else heard of something like this happening?

You prob changed IPs ;) Or did you change your modem?? Maybe its not just a cable modem but doing nat?

I am on comcast, and I assure they are not blocking any ports.. I was just on my ssh server from work today, along with my openvpn server, etc.

And as you can see from this test open

a dyndns account would get around your ip's changing. it is free.

Uhm, except that can't be it because I'm using that same site (CanYouSeeMe.org) and it can't see anything.

And I have a dyndns account but that doesn't help since this isn't my problem...

No new network hardware; it used to work, now it doesn't, and I can't think of anything that's changed. It's driving me nuts.

software firewall -- another big problem.

Are you sure the applications are listening -- what about your private side IP changing? Now your forwards don't work either.

Or you router just not doing the forwards anymore. Reset them up or check with PC you connect to the wan side talking to pc on the private side.

Internet security suites include a firewall as part of the package. Take a look at your av/internet security/antimalware software and disable the firewall.

Post or send your IP and get someone to do a port scan, I'll do it if you want.

Edit I very much doubt its ALL of them how would you post on here, send email, go on MSN etc etc

My guess, since he says his external did not change and canyouseeme.org detects your IP for you -- so kind of hard to put in the wrong one. Is either his private IP changed, so forwards are forwarding to wrong machine or nothing. Or he installed something that changed his firewall setting or installed its own, etc

He never answered my question on what "modem" his is using either -- maybe it can do nat and it got reset to doing that? Look on your routers wan internet status and make sure your on the same public as canyouseeme is saying.
