I have SOCKS5 proxy configured and want to work with the git repository, originally cloned from ssh:... So when it tries to connect the error "Network is unreachable" appears.

There are a few possible solutions:

1. Use GIT URL rewriting and use https:// with proxy option. Probably should work well for github repositories.
2. Use port forwarding and something like iptables/ipfw to rewrite address xx.xx.xx.xx:22 to 127.0.0.1:10yyy

I'm trying to do #2. I have limited knowledge in this area, but know that I should use something like iptables. But then I discovered that on a Mac I should use ipfw. And then in the ipfw man page it told me "This utility is DEPRECATED. Please use pfctl(8) instead".

So what I want to do is to rewrite xx.xx.xx.xx:22 to 127.0.0.1:10yyy and remove this rewriting. As I read, the pf.conf line should be

rdr proto tcp from 127.0.0.1 to xx.xx.xx.xx port 22 -> 127.0.0.1 port 10yyy

But how to add (and remove) this rule from command line?
