Region : UnitedStates

Model : TL-ER6120

Hardware Version : V1

Firmware Version : 1.0.2 build

ISP : Time Warner


I think I have found a problem with the ER-6120 router using an access list. I want to block all DNS but my local provider’s DNS server. I added an access list to permit DNS from local provider
ANY 209.18.47.61/32 Allow DNS LAN Always

I then added a deny all DNS.
ANY ANY Block DNS LAN Always
DNS is blocked at this point. I tried adding priority 1 to the allow statement which did not fix it. Would someone confirm what I found? Does anybody see an error with what I am trying to do? The router is fast otherwise.

I just figured out the issue. If I allow 192.168.0.1 the router instead of the outside DNS address then it will work. The router is the DNS relay. The router is blocking the LAN side before the router translates the DNS to the outside WAN address.
