I have diagnosed a problem with the WRT100 router which I had hoped would be fixed with a firmware update but was not with the most current (v1.0.02). I have asked Linksys to troubleshoot the issue and they have passed it to software engineering at my request but it could be weeks or months and nothing may come of it so I'm posting this to linksys forums so others can confirm my findings with their equipment and confirm that it is really a bug! If you have your DHCP server enabled in the router (most do) and receive DNS settings from your ISP on this router they will always sort to the top followed by the router itself. If you specify Static DNS entries they will sort to the bottom. This is just the opposite of what most routers do (including all the other Linksys models I've used). The result is sorted... ISP, ROUTER, STATIC. If you as an administrator specify a static DNS (say for use with an active directory domain controller or to use OpenDNS) the intention is that it be used first. For this to happen it must appear first on the list (DHCP) .. not last. To work properly we need this order to the DNS entires... STATIC, ROUTER, ISP. Static (manual) entries should always proceed any automatic setup items. Do you have a WRT100? What order does yours sort the DNS entries for your DHCP client requests?
