My IP is static, so the monowall should always be getting a good
lookup... and the lookup actually "works" for monowall.

try to ping google.com, it resolves the IP perfectly.
PING google.com (126.96.36.199) from 188.8.131.52: 56 data bytes
64 bytes from 184.108.40.206: icmp_seq=0 ttl=245 time=348.544 ms
***Now on my client linux pc***
from konsole > nslookup
server set to monowall IP
google.com - request times out
cale (one of my pc names manually added to list to override)
(all correct - resolving local names but not outside names)
so i change dns server to my ISP's

Default server: 18.104.22.168

But would this cause _all_ pc's on the network to stop DNS requests working?
