[AG-TECH] Using Access Grid with Ethernet Bridged OpenVPN

Hi Doug,

A while back I tried OpenVPN (mac client @ home behind NAT/Router--- 
 >linux server on open network) and although other stuff worked, I  
could not get AG going (I was not using bridged mode though.....I was  
using the other mode.....don't remember right now).

I have since tried to run it with an L2TP type VPN (Mac notebook  
running osx behind NAT/Router --> Mac OSX Server on open network) and  
AG3 works quite well. I've been able to get somewhere near 14-16  
videos smoking my 6Mb dsl link. I've also tried this from behind a  
firewall at work (mac notebook behind a really strict firewall  
blocking ports 1024+ UDP/TCP ---> same mac OSX server on open  
network) and AG3 works fine.

So to answer your question OpenVPN did not work for me and I admit it  
was not the same situation you're describing. L2TP worked fine behind  
NAT and also behind a pretty strict firewall.
