Allowing SSH Through tinyproxy

Recently, I sat-up an OpenVPN Linux server, so that I can get into my internal network from anywhere. In addition to the OpenVPN, I ran tinyproxy--a light-weight HTTP proxy daemon--on this server to provide the routing between the internal and external network. However, when I attempted to access another one of my internal Linux server through SSH, I got the following error message:

Proxy could not open connnection to [SERVER]:  Access violation
ssh_exchange_identification: Connection closed by remote host

After tinkering around with tinyproxy for a bit, I found out that tinyproxy, by default, disallowed most ports from using the CONNECT method. The only two ports it allows in the tinyproxy.conf file is the following:

  ConnectPort 443
ConnectPort 563

So you can add port 22 to that list for SSH. And you can add additional forwarding ports. However, if adding individual ports is a mess and you aren't concerned with security, you can comment out all of the "ConnectPort" settings. When you do, all ports are allowed by default.

Thanks, I was trying to switch from using squid as an http proxy and this was tripping me up.
