This is an overview of the network we're working on:
Network
IP Addresses
NAT on FW
Private
pvt. 172.16.X.x /21
hidden behind 1 public IP
DMZ
pvt. 172.16.Y.x / 21
static to a public IP
The whole network is in the same NT domain.The mail server is in the DMZ, running Exchange 5.5..SP3 onWinNT4.0. We just moved the mail server from the private network to the DMZ.
The problem is, we don't find database sync'ing happening between the mail server(NT BDC) and the PDC which is in the private network. Otherwise, the mail server is functioning normally wrt sending and receiving mails. This sync'ing is essential, else, a user changing his password will have authentication problems the next time he tries logging onto the mail server as Exchange uses NT for authentication.
As far as FW policy goes, between the pvt n/w and the DMZ, the following
services have been enabled:
http, https, smtp, pop3.
Does this problem have anything to do with the FW or is this an NT-related problem? Whichever, could you help me out here?
Thanks and regards.
Vinod.
