Hi;
I have a DNS (named) server running on a FreeBSD 4.4 box firewall.
ipfw allows queries to ports 53 and 1024 from any IP inside the private
network (internal interface) and only certain ISP IPs on the external
interface.
I need to open those ports to any IP on the external interface.
Is there any security concerns I should have if I do this ? The only
services I have running are ssh (restricted to specific IPs) and squid
(local only).
Thanks, -
