I'm trying to get a client on the internal network to be able to publish his address to the ils server at laplink.com, so that another internet user can access his computer and control it over the internet. It used to work when an ISDN router was installed using NAT, but since ISA server has been installed it hasn't worked, I've allowed all traffic in and out, setup all the rules to allow everything, it still doesn't work. Any ideas?
