Mark,

So, if I use port forwarding on my router, and add a printer to my remote workstation with the following printer address ( http://Router_Name:631/ipp/PrinterShareName ) in order to print remotely, am I putting my network at risk?

You may want to check out Hamachi at https://secure.logmein.com/products/hamachi/

It's incredibly easy to set up, and creates a secure hosted VPN. Since it's hosted you don't have deal with opening any ports, because each end reaches out to the host to establish the connection, and the host patches them together. It's free for up to 5 connections (including the server). You can pay for more connections, if needed.

This would allow you to print to a shared or networked printer, not to mention allow Sesame to communicate without you having to do any port forwarding.

Some. Probably not a whole lot. The main risk would be that someone else uses (abuses) your printer. But, any open port through a firewall weakens the firewall.

Sesame Client over Internet is getting disconnected if it remains idle for about 5 minutes. I know there has to be some timeout setting either for TCP-IP or UDP ports or Router firewall or software firewall on server. I am not able to find as to where do I change the setting of the timeout period. I will appreciate if someone guides me to setup longer timeout period.

Sesame client over the Internet is very fast as compared to Remote desktop or PCAnywhere. I like it a lot.

What OS, firewalls, etc... are at each end? We are using TCP only, so you needn't worry about UDP.

We don't have to pump an image of a user interface through the network.

Thanks Mark.
Server End - Windows7, Linksys Router, AVG Firewall
Client End - Windows XP, Linksys Router and ZoneAlarm firewall

Sometimes Client side is used as Server and Server Side as Client depending on where I am.

Before you try anything else, as a temporary experiment, turn off all of your firewalls and try to stay connected with no activity. If you can, then turn on the firewalls one by one and try to stay connected with no activity as you turn on each. That way you can narrow down whether it is a particular firewall's settings.

Thanks Mark. I will do that and report to you the results. Router firewall will remain I guess. Is there any way to temporarily take that down? I believe that is hardware firewall.

You can usually turn off a router's firewall in the router's configuration screen. For now, concentrate on the software firewalls. It is likely the router that is giving you grief, but we have to be a lot more careful not let in the bad guys and it is actually doing that, while the supplemental software firewalls are probably only stopping people who are already on your network from getting on a specific computer, if that much.

BTW: it is likely that the problem is on the notify port, not the main port. Are you sure both ports are open through all the firewalls?

Turning off firewalls (namely AVG and Zonealarm) on both the sides at the same time has no effect. Client stopped working after 10 minutes.

I suspect that the notify port is not open all the way through. Sesame server runs a "ping" through the notify port. If there is no activity on the main port and the ping cannot get through on the notify port (after quite a few tries), the server will disconnect the main port, under the assumption that that client is no longer actually there.

How do I check notify port? On both side routers port 20000 and 20001 are opened.

Other than by going through every device between the client and the server and making sure all is set... check the sesame logs on the client and the server for a sesame disconnect error at the same time that the client disconnects. Look particularly for S_COM errors (communications). 510091 is especially popular if sesame's connection is timing out.
