Firewall/NAT

Hi,

Apologies if this is a newbie question, but I've searched and googled and couldn't find an answer...

I'm running m0n0wall 1.33, with a fully routed /28 IP block. I've disabled NAT by checking the "Enable advanced outbound NAT" checkbox. I have *no* NAT mappings defined, however ipnat -lv still shows a single NAT mapping on the WAN interface for DNS queries:

Code:

List of active MAP/Redirect filters:
map ng0 from xxx.xxx.xxx.187/32 to any port = 53 -> 0.0.0.0/32 tcp/udp

List of active sessions:
MAP xxx.xxx.xxx.187  65419 <- -> xxx.xxx.xxx.187  65419 [yyy.yyy.yyy.20 53]
ttl 1164 use 0 sumd 0/0 pr 17 bkt 1378/1378 flags 2
ifp X,X bytes 84/68 pkts 1/1 ipsumd 0

How do I remove this NAT rule? and where does this come from? All other traffic is successfully routed without NAT, so I'd like to remove this last vestige of NAT :-)

Thanks!
Chris.

The port 53 tcp/udp rule looks like it's on VPN interface. Anyhow You should be able to edit all NAT mappings manually directly on the config file, but You should be careful. doing that.
