I want to have isight / iChat between two sites, multiple
connections simultaneously, can't port forward
as that 1-1, firewall supports SIPS, but does iChat?
I will get a site-site VPN up at some point, but for
now.. is there a way??????
afaik, as long as the NAT does consistent port translation, you can do
iChat AV sessions even if both peers are behind NAT. There is a handy
utility called natcheck which can help you determine if your NAT
devices are p2p friendly in this respect.
Note that the GUI version linked on that site won't work in panther.
Running the command line version looks something like this:
