I'm trying to block access to a certain DNS (8.8.8.8). Now, instead of blocking this address using Access Control (Deny), I've turned it around and used Access Control (Allow). There are reasons for this that are a little complicated that don't really matter at this stage. I've set up some simple rules to do what I think should work but I've had no luck

First of all I've set the router DNS to 8.8.8.8 and 208.67.222.222 (OpenDNS).

In Access Control I've selected Allow setting and have 3 rules:


























Rule Name
Host
Target
Schedule
OpenDNS
192.168.1.1-192.168.1.199
208.67.222.222
Permanent
Good Machines Low
192.168.1.1-192.168.1.118
Ports 1-52
Permanent
Good Machines High
192.168.1.1-192.168.1.118
Ports 54-65535
Permanent


I'm on a machine with IP address 192.168.1.111. Now, as far as I can tell, the rules above should only allow traffic through to 208.67.222.222 AND IPs between 192.168.1.1 <> 192.168.1.118 on all ports EXCEPT port 53, which is the DNS port. Thus, 208.67.222.222 as a DNS will work (allowed by the first rule) but 8.8.8.8 Port 53 should NOT work because it won't be allowed by any of the rules. However, it's still using 8.8.8.8 as a DNS.

Can someone from TP-Link confirm this bug?
