Port 3268/tcp used for the msft-gc service

is it safe to open up this port in my network
i have 2 vlans
server vlans (where active directory resides)
worksation VLan (users)
im having issues using active directory users and computers tool from my worksation
due to not being able to contact the global catalog server efficiently
all traffic (VLANs) flow through out firewall
if i opened up this port on the firewall so that it was opened between the 2 vlans would solve my issue

do i need to open this both incomming and outgoing?

Yes it is safe it is on your internal network and 3268 is how you communicate with a GC, common port that is open and needed if DCs were in different segments/locations(common)   http://technet.microsoft.com/en-us/library/bb727063.aspx

You should enable the same on vlan.
