(0)Configured all-in-one server (windows 2008) IIS + DNS + AD (the only domain controller)internal IP:192.168.1.200 computer name: w2k8
(1)registered a public domain mydomain.com from ISP
(2)added HOST entry (A) mylan.mydomain.com from ISP domain entries, and point to my home router's only public IP address (say 18.104.22.168)
(3)On the home router (LinkSys Wireless-G), Made port forwarding (port 80 for web) to my all-in-one server 192.168.1.200
(4) I can successfully load my server web page from any public browser with http://mylan.mydomain.com/...
How do I make the my internal server "w2k8.mylan.mydomain.com" to get ping from any remote internet PC? I tried port 53 (suppose to be DNS port) forwarding. I also tried play with ISP domain NS entries, but can't make it. I think it's quite possible. Please help.
