Port forward locally

So I was trying to test out a web service deep inside a private network which I had to create a number of SSH tunnels to access.

I used LocalForward to get at the port, but as it was a privilage port I could not create the forward without being root

I guess I could have setup ssh tunnels as root.. but it was already working, instead to did a local forward to a non-privilaged port, then did used iptables to do a local port forward

sudo iptables -t nat -A OUTPUT -p tcp -d 127.0.0.0/8 --dport 80 -j REDIRECT --to-port 5580
