ENDIAN Firewall - dns server -bind 9 behind EFV 2.41 comunity edition won`t resolve names

Hi,
I have a problem with configuring efw to publish dns server.
I have setup orange zone with private addressin 192.168.100.0/24
i have bind dns server on ip 192.168.100.12
i have efw interface on ip 192.168.100.3
100.3 is dg for bind
bind can ping google.com
i have a port forwarding/ nat rule that says:
all tcp/udp that comes from red on port 53 translate to 192.168.100.12
on efw log i see that connections are alowed , but dns server doesnt work.
I put clinet machine on 192.168.100.22 and say that dns server is on 192.168.100.12 and it resolves names normally.
I put ISA server on same ip adresses as EFV is and shut down EFV , my dns server works , dns resolving works from internet.
So this means that i have missed something in configuration of EFV , but can`t figure out what?
Can anyone help please?
Maybe som guide how to publish dns server with EFV?
