I am almost operational (and I will register then), but...
Config for this question:
All systems publicly addressed (I have a 64 address block assignment).
DNS/SMTP/POP3 server behind firewall
Rules
ANY client ANY protocol 'HOME' allowed
'HOME' ANY protocol ANY client allowed
That is wide open, I think.
Works fine. receives and sends mail. DNS out works
But a client outside the firewall cannot access the DNS server behind the firewall.
I tried adding a rule:
ANY Client DNS 'HOME' allowed
and this did not help.
Why is DNS not working? Is it UDP related?
