I'm trying to configure our LAN so that regardless of which DNS server is configured on the client, it is redirected to the DNS server on the LAN, say, at 192.168.1.191.. Of course, the DNS server itself needs to be able to reach out to the WAN itsel...

Hi. I thought I had this down pat, but it turns out I didn't. This is a CISCO 3925.. Single outbound IP, and a bunch of LAN clients using 192.168.x.x very typical setup.NAT is working fine, except I can't allow an incoming port to be mapped. I have ...

Hello. I have a basic access list applied to the WAN interface, that needs to allow incoming DNS queries, incoming PING requests, and permit any traffic that originates from the LAN (so things like "related", "established" etc). I have so far:ip acc...

You probably should try a factory reset and see if that helps things (hold reset down for 30 seconds).. If the firmware is corrupted, re-flashing might help..

Many thanks.. I did that, but I suspect some devices would try to directly reach out anyway.. I wanted to silently redirect them to the LAN's DNS..

The clients may have remote DNS's configured, I wanted to transparently redirect them to the local LAN.I already configured the DHCP server to advertise the LAN DNS server only, but in case the clients are "clever" and they have their own hard-coded ...
