I want to port 127:0.0.1:80 to the other machine via SSH, how can I do that? I tried adding -R 8000:localhost:80, but it doesn't work. By the way, PHP is also installed on localhost, maybe that's why?

Only root can bind ports numbered under 1024.
The cleanest way is just to use local port 8000:
ssh -R 8000:localhost:8000 otherhost
Alternatively,
sudo ssh -R 8000:localhost:80 me@otherhost
(It's really better not to run this as root for the sake of security - just use another port.)
If you must use root, and you're using ssh private-key authentication, you may need to tell it which identity file to use. For example
sudo ssh -i ~/.ssh/id_dsa -R 8000:localhost:80 me@otherhost

Thanks, but when I try to do that via sudo, I get Permission denied (publickey). Oct 18, 2013 at 22:43

Thanks again, I logged it via sudo successfully, but it doesn't work... I just see 404 not found on 127.0.0.1:80... Oct 18, 2013 at 22:51

That's probably a different issue, perhaps connected to your server expecting to see a different virtual host name. Have a look in the server logs.– poolieOct 19, 2013 at 6:55
Judging from what you've just said in chat, this will let you access the server's port 80, from localhost:8080 (you'd need to run this as root to get it on localhost:80, which I don't advise if you can avoid it).
ssh -L 8080:localhost:80 host
