Although I am all for programming and in-depth understanding of technology myself, I realized that the problem with the "geeks only" approach in the real world is that many organizations with a limited technical background need either a standard or a fool-proof setup for reliable day-to-day operation . The current open-source AG architecture is geared toward large, well-equipped, and well manned nodes where AG administrators can and are willing to fill in all these technical gaps. In reality however, the AG community is rapidly shifting toward a much more diverse user group where users of different shapes and sizes would like to participate with very substantial differences in experience, technical capabilities, and available infrastructure. I my opinion, the open-source AG solution (that has great potential and a bright possible future) will survive long-term only, if we are willing and able to accept the paradigm-shift and produce more solutions that are at least close to "turn-key", especially regarding new security challenges. A great example is the OpenVPN / Bridge Server hybrid I mentioned, developed by Joe Stone.

This is found in the VenueClient under Tools->Preferences->Bridging; each bridge is listed with its related port range (the rightmost column in the list, you may need to stretch the preferences window to see it). The default port range for unicast bridges is 50000-52000, but some bridges do use alternate port ranges so you should check.

All that you have to do is forward the bridge ports of the Bridge Server to your internal IP. Generally, I forward 30000 to 65535 to my internal IP. Now if you're behind NAT in a campus environment it may be a bit tricky to get the networking folks to forward those ports to your machine.

I've looked through the ag-tech mailing list and there's talk of problems but I can't find specifics. Thanks, George
