Force Open/close/block Ports?

[cheesypfz]

I was wondering if anyone knew a good way to force open, close, or block ports without having a router login. I know when I'm out and about, and I connect to a public wifi, I need a login. I try to ssh around, but of course all ports are closed for me to get though. It would also be nice to be able to close ports on routers without having to log in. Has anybody found anything like this?

Can you clarify all that please?

Which routers?

In what sense open/closes ports? Allow incoming connections sense or some thing else?

What are you trying to 'SSH around'?

So sorry. Let me clarify.

Which routers?

What brings up the question is an Apple Airport Extreme, but on all routers would be nice.

In what sense open/closes ports? Allow incoming connections sense or some thing else?

Yes, allow incoming and outgoing connections, or don't allow incoming/outgoing connections.

What are you trying to 'SSH around'?

Generally login's for public wifi and things like that. SSHing my traffic though a server back at my house to get around them.

Thanks for the quick response.

For opening and closing ports you can use UPnP, except it's horrifically insecure and should definitely not be used. It does what you wanted though (unauthenticated port forwarding, which is exactly why you don't want it on).

See DNS tunnelling for using wifi for free.

Excellent! Thank you very much.
