Hi Tom, I need to publish more 4 http sites that working on different ports. I published them using Server and Web publishing rules, but they do not operate well some times up and the others down also destination sets do not work properly. So if i can make mapping like One-to-One NATing i can dedicate external ip to internal ip and eliminate the use of server publishing rules. I know i'll lose some benfits but i gurantee all links on the different ports will operate well. Plz, If you have another more accurate method tell me as soon as possible. Thanks, Amr Omar
