<DIV dir=ltr><FONT face=Arial size=2>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.</FONT></DIV>

<BLOCKQUOTE cite="" type="cite"><PRE>George, I've used AG from home several times and I'm behind a Linksys
router. 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.

<BLOCKQUOTE type="cite"><PRE>Hello,
Could someone with experience in this area tell me the issues/problems with receiving traffic from a bridge server if I'm behind a NAT. I've looked through the ag-tech mailing list and there's talk of problems but I can't find specifics.
Thanks,
George
