Spooky. I was just pouring over the same problem myself for the last couple of hours. My search for a solution of getting through firewalls leads me to consider OpenVPN as the best solution.
But before I launch it, I would like to ensure that traffic going through it is used only for supporting AG sessions. I'd be willing to provide some benchmarks when using this but am looking for help to ensure that I don't open all of the institutions resources to AG participants that aren't part of it.

(www.openvpn.net<http://www.openvpn.net>) OpenVPN supports TCP instead of UDP, and I have users behind Firewalls that restrict outbound UDP and I have a server that I could use as the endpoint that sits outside the firewall. I know there would be a performance hit using TCP, but on a high performance network it would be interesting to know if anybody has given it a try. -Doug B OCI/NSF Joseph Stone Senior Informatics Manager Family Medicine Community Health, Medical School, Univ. of Minnesota Suite 220 Dinnaken 925 Delaware St. SE Minneapolis, MN 55414 (612) 624-3192 [email protected]<mailto:[email protected]>
