Authentication and Firewall

[lech]

Hi,
I'm trying to set up domain Authentication between two domain controlers with a Netguard 4.11 firewall. Trust relationships have been set up during build on local lan. I have created appropriate Lmhosts files on both machines and opened ports 135 > 139 but if I try to access accounts from external domain to internal domain in for example User Manager the Domain Controler cannot be contacted. If I set the firewall to allow all ports it communicates OK!!!
Any Ideas?????
Thanks

Enable unicast traffic on UDP ports 137 & 138, and TCP port 139. Mubashir
