OK I think I've read teh FAQs and checked the forums and I can't find an anser yet.

I have an ISDN router, which dials up and gets itself an IP address whenever i access the net, I want to set up it up to open up the ports to use gnuttela, according to the FAQs i have read I should set gnuttela up force my IP to the firewall IP addres, Then forward to the port to my IP address from the firewall, but as my firewalls address is dynamic i can't. and my internal address is dynamic, i could set it to static I think, but my tcp/ip anit that hot so i don't know!!!? Any help would be appreciated!!!!!

Cheers burt
