Firewall question

[Habermann, David (DA)]

I do what you are describing routinely.  My method (all W98 machines) is:

1) Start up vncviewer on my home pc.
2) Send a specially formatted e-mail to my office mailbox (e-mail is the only inbound traffic our firewall will accept).
3) A software agent monitors my inbox for these special messages.  When received, a command is sent to WinVNC to trigger a "server initiated connection" to my homepc (outbound through the firewall now).

These connections occur on port 5500, so you will have to set up that port on your firewall as well (or you can look for some hacks previously posted to this list that allow this port number to be adjusted.

Hope this helps.

Thanks for the reply! Port 5900 is currently open, as I *can* connect from *inside* the firewall to a host outside. The problem occurs in that I need the connection in the other direction, .. i.e. I need to make the machine *inside* the firewall the host, and I cannot see a way to connect from that machine as a host to a remote. (It is running an off-net IP address.) IOW, I need the 'host/server' (behind the firewall) to call the 'remote' because the host is NAT and can only support an outbound connection.
