Lightbulb Firewall issue

Dear All,

Can any body tell me. If there are two host and they are not able communicate directly to each other due to a firewall in between. Can they able to communicate with each other by having a server as an intermediate.

Though I know that until and unless we open a port for communication at firewall they will not be able to intract each other. But someone told me that we can overcome this thing by having a sever as an intermediate. Is it possible?? If yes then HOW?? What special functionalities that server will be having??

Waiting for some +ve responses.

It is done by installing proxy servers on the firewall..

The job of a proxy is to sit in between and do some type of control.
The type of proxy depends on the type of connection/service..

You can search Google for suitable proxies..

try tunneling ur requests through an open port in your firewall to the outside server which in turn could forward ur request to the destinatation computer by sending it through the port it is intended.
