I have a site-to-site VPN with two networked printers connected, one being a laser printer with built-in network card, and the other a Genicom LA36W dot matrix printer with LPT print server connected. I have an Axis 5400+ print server connected to it, and also have had a cheap Edimax device connected but both have the same problem.
When trying to print from a machine at the other site the connection is lost until the print server (or printer) is powered off and on. As soon as the device switches on the printing commences and print requests succeed for at most another 5 minutes, then the connection is lost again. The computer at the other site is unable to access the web interface of the print server until the device is powered off/on. Computers within the same site can print to the print server no problem, so it is obviously an issue with the print server holding the VPN connection.
The IPSEC VPN is over two Draytek 2800's. The print server always maintains the same IP because it has been reserved in the DHCP server. What could I try to stop it losing the connection? I have given this 500 points as it is quite urgent.
