My senario...we're building a brand new network, and I have a new T1 for Internet with HellSouth. They manage the router and forward everything. Behind that is my firewall (SonicWall 230). The firewall does NAT for my network, and I can open up ports for my new Exchange Server 2000. Internal name resolution is done with Windows 2000, Active Directory integrated DNS. My internal DNS is pointing to internet root servers and works. I can surf the web, and even send out mail. My internal domain name is like company.local. My public domain name, say company.com will soon point to bellsouth name servers. Do I get bellsouth to put an MX and A record on their name servers pointing to my WAN address? or do I put those records in my private DNS? Can I tell hellsouth to just forward all traffic bound for company.com to my WAN address, or should I do something different?
