Step 1. Find a port that can reach the internet
Step 2. SSH tunneling.
Step 3. ????????
Step 4. Profit

VPN would probably be best. Or you could use SSh tunneling but that would not be the "simplest" method...

Lol there aint nothing more simple than an SSH tunnel.

But do you not agree using a VPN would be "easier"?

No I dont ?
Setting up a VPN is more work than an SSH tunnel , that is basically one command,  pretty much unbeatable.
Not to mention that VPN traffic is more likely to be blocked.

True about the VPN traffic, however if you use a PPTP VPN, it is very simple and is as easy as entering a username and password. And obviously the address for the first use.

Everyone to their own :)

You are aware that PPTP is not really considered secure in most implementations?
Another really neat trick is tunneling all traffic over DNS (UDP53) that can get you out almost everywhere.
There is however a theoretical speed limit to it.
When you can do nslookup <SOMETHING> and it actually returns an address you are good.

No I was not aware of that. But security is not a major factor here, is it?

Also as for that example you just gave, no fucking idea what it is. I am a newcomer to networking, still studying it.

I'm going have to go with SSH tunneling here as well. No setting up necessary as with a VPN. Just punch it right through port 22.... or whatever obscure port you want really.

Yes and if they do nothing but filter on certain outbound ports I would also suggest to set the daemon on port 80, that way it can be easier to get out, same goes for 443 (which might be better idea).

And i thought DNS uses uDP instead of TCP. Any constraints or consequences to my browsing using this method? Just asking
