RE: Securing a Win2k DNS server outside firewall...

["type_o" <type_o () canada com>]

Hi Mike,

To be honest, I don't like the tcp/ip filtering in win2k. It gave me problems with
udp traffic, and it cant block icmp traffic properly.

I prefer using ipsecpol to create a good policy. it looks like a mini-personal-firewall.
simply use something like:

ipsecpol -w REG -p "DNSPOL" -o
ipsecpol -x -w REG -p "DNSPOL" -r "BlockAll" -n BLOCK -f 0=*::*
ipsecpol -x -w REG -p "DNSPOL" -r "AllowICMP" -n PASS -f 0=*:*:ICMP
ipsecpol -x -w REG -p "DNSPOL" -r "AllowDNS" -n PASS -f *+0:53:UDP

you can find ipsecpol.exe + help in the resource kit of win2k
