Having absolutely no idea what I am doing, but

I have put the client on a NS2 connected to comcast, defined it on the server (ns5) also connected to comcast.

configured/saved and the tunnel is active. from the server I can connect to any of the 6 nodes on the NS2 client side. I can not connect to the server node from the client side. Is this correct?

it would be nice to have another remote try...
