I am currently using SSH tunneling to connect to the internet via a remote computer using the -D ssh argument. I've recently run across a problem with this solution -- the SSH protocol decreases the MTU significantly. I'm not at all worried about security, and am just looking for the most light weight way of creating a similar dynamic application-level port forwarding solution.

How significantly? The MTU has to drop a bit to fit the packets inside the tunnel.. It shouldn't be drastically, what are you seeing? –  Paul Oct 20 '11 at 23:16
