As I was setting up a tunnel on my gnatbox (which uses DHCP to pick up its external NIC configuration) to pass port 80 through to one of the machines on the protected network (which are all private static IP addresses) the following question arose.
Since one must specify the external IP address as part of the tunnel's configuration, what will happen when DHCP next kicks in a changes the external IP address? Will the tunnel stop working? Or is there some symbolic way of telling the tunnel to go from "EXTERNAL" (which I tried and it did not like)? Regards Stephen
