sshuttle
Transparent proxy server that works as a poor man's VPN. Forwards over ssh. Doesn't require admin. Works with Linux and MacOS. Supports DNS tunneling.
Not in Iran, and the following would be trivial to detect, but this xtables module may be of use. It runs entirely in-kernel, so if it works, it shouldn't cause much of a performance hit. Only try this if your only goal is bypassing censorship; it won't do a very good job at hiding the fact that you're using a VPN to a human observer.
Try to use udp2raw to hide the protocol https://github.com/wangyu-/udp2raw
There are several ways suggested there. And as an alternative to SSH tunneling, you can also use sshuttle which is faster and easy to set up.
