Now he wants to use another one of his publicly registered static ip's for his mail server, which we are trying to plug into one of the unused jacks on the built it hub on the R7100. The problem is that we can not get the R7100 to respond to more then one public address.

Did you guys try 1. enabling 'nat translations' on the router. 2. setting up 'nat server list' and if one already exists, (which is generally the case) add your mail server's ip to the list. I believe your problem can be solved by doing just that. good luck! Rahul Jason Corekin wrote: > I have a friend who is trying to setup a Netopia R7100 sdsl router.
