Dear all,
My remote Linux box is behind the proxy server. So,I can't see it from the outside world. My remote PC has registered IP. How can i access my remote PC from the external network?
Any ideas!!!

Could you expand on your explanation.

What service do you want to access?

Why is the proxy blocking?

Do you have a firewall/DMZ setup?

Yes, i want to access via SSH. My remote PC's network is using Proxy Server for internet. We can use SSH on that network. Thanks!!!

Two options you may like to consider:

1) Configure your PC with the registered IP to act as a VPN gateway.

2) Implement a DMZ and configure it to permit SSH access.

Option 1 is the preferred and a more secure way.

Adding to what Harry has already replied, you can forward the request using iptables. Since the proxy server is on a public network, add a higher port for ssh and write a iptables rule to forward it to the linux box behind the proxy server. When request comes to that port it is forwarded to your machine that is behind the proxy server.
