As others have pointed out most routers/switches with NAT/DHCP enabled won't respond to the external address on the internal intefaces for various reasons. You can try looking through the router's management interface (or the manual) for a way to turn that off but AFAIK very few provide that option. I have a similar setup with a low end Netgear and there's no way to turn it off. Fortunately I rarely use windows and I don't have many internal boxes so I can use the easy solution: I just put the necessary translations in /etc/hosts on each machine. The harder way to do it is to set up a caching DNS server with the appropriate translations. The DNS route will work with your laptop if its set to use DHCP on both networks. The first response you got at experts-exchange is basically the same as what I just said. The fact that you already have a DNS server shouldn't matter. If your main server is already set up for caching you should be able to add the necessary translation but I don't know anything about the MS DNS software so maybe not. If you have a spare machine (or your DHCP server) put a caching server on that and tell it to reference your main DNS server. Once you do that set the DHCP server to tell internal machines about the caching server. Then your laptop (and all the other boxes) should get the caching server when they request/renew their leases. If you were running FreeBSD I could show you exactly how to do this... :) --- Brandon Fosdick http://www.terranspace.org -- http://www.piclist.com#nomail Going offline?
