Hi Ben, Excellent solution. There are a number of options that allow this type of "back-channel" access. Not that I would consider any of them secure, but there are a number of solutions. Thanks! Tom

What you're asking is more about networking than the remote control software. As others have said, if you're going to be initiating a TCP connection to the remote, there has to be a port open. The only way around that is to have the remote *always* initiate a connection to a system you control, and then use that as a back-channel to get in to the remote when you need to. You could, for example, use the open source OpenVPN program to initiate connections to an IP virtual network dedicated for remote control purposes; just don't assign a default gateway. But this will mean there's a lot of network traffic all the time, for the VPN tunnel's purposes. Depending on your situation, it may also create a security problem, as now there's a way through all your firewalls. Does Dameware offer a more lightweight versions of the above workaround? -- Ben ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~ ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
