Hi Folks,

m0n0wall (v1.2 generic-pc) is continuously sending some packets to my
ISP's DNS Server. I'm using PPPoE on WAN. The DNS Servers are served
by my ISP on dialup.
Since m0n0wall is sending packets every second, it makes me about 17MB
traffic per day, resulting in 500MB per month.

Packets are always sent to the DNS Server while WAN is up. No matter
whether LAN interface is connected or not.
DNS Forwarder & DHCP Server is on.

If you need some further information just let me know.

Best Regards,
David
