Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am in a network with clients, a proxy, and a router/gateway. The proxy is set by default in every client, and only allows the TCP ports 80 and 443 and the UDP port 53.

I need to be able to reach another services (like SSH) through the gateway. I've tried a VPN(openVPN running on port 443) but the connection failed(i don't really know the reason).

What can be done? May i somehow connect directly to the gateway(as it is in the same network)?

Most likely your friendly network administrators have set up some sort of firewall between the gateway and the internet connection that is preventing access from internal hosts other than the proxy.

Sounds like you are trying to bypass the security set up by someone else to stop abuse of the network. You should go to the admins with your (valid) requirements for doing this, and ask them for assistance.
