I have a problem about DNS request timeout.
Use M0N0 with NAT to translate many private ip to one public ip.
My private lan has about 200 computers at the same time.
About 10% computers have DNS problem.
Using nslookup command in DOS mode reponse DNS request timeout.
DNS server is in public domain.
Using nslookup command in DOS mode many times will connect to DNS
server correctly ,
then browser work fine.
I set tcpidletimeout to 600 sec. This help me reduce NAT
state size with TCP packet.
DNS is UDP packet.Or have other reason.
How to solve this problem? Thanks a lot.
