I want to be able to print to a remote HP JetDirect printer across the Internet.

I am having difficulty though with either the Proxy Server and/or Firewall we have at our end. Of course I have added a rule to allow Port 9100 through the Firewall, but it has been suggested needing a SSH client/server tool to provide some kind of transport protocol for the output??? Without this the data has no way of finding it's way to the printer?

Will AT provide this kind of assistance?

Thanks in advance.

Absolutely!!!!

Plus it shouldn't require any modification of the firewall to let the traffic through. It's all securely tunneled through the SSH connection.

The feature is called 'Port Forwarding' and is located at Options->Properties->Connection->SSH2->Forwarding.

As long as the server that you SSH2 to lies on the remote network (the one with the printer), you can define a port on your local machine that gets forwarded to a port on a machine on the remote network.

For example, machine A and B are behind the firewall. Machine A is your SSH server and B is your print server listening on port 9100....

Creating a forwarding definition in AbsoluteTelnet that redirects port 9100 on your client machine to port 9100 on machine B. Three rules to remember to make it easy:

1. When you specify the name or IP address of 'B', it needs to be the name or IP address that 'A' would be able to use to contact it.

2. After you establish the connection, check Options->SSH Info to make sure the forwarding port is working

3. You now have an open port on your local machine that makes your machine look like a print server. Any other machine on your local network can connect to your machine at port 9100. The SSH protocol simply forwards all connections/data to machine 'B' on the other network.

If you need any more help configuring this, let me know.
