Afternoon all [[:)]]
Good afternoon forum board!
I need some help, (again) sorry!
We have Site A (Parent) Site B (Child)
Both sites have Domain Controllers located in each, both doing DHCP and DNS
We have set up our RED device at Site B (Child) all appears to be working ok, we can VPN on to the Domain Controller at Site B without any issues, we can also ping Site A from Site B and vice versa
However, we have an AD replication issue, our AD's aren't speaking to each other properly, we haven't been able to work out why this might be, but we are of the opinion that the issue might lie with the Config of the Sophos UTM 425 appliance and the way that the RED device has been configured
Site A uses 192.168.120.0/24
Site B uses 192.168.121.0/24
The parent site replicates successfully to the child site, but any changes we make in AD in the child site doesn't replicate successfully back to the Parent site
As I said, we can ping back and forth, but AD isn't replicating and when we run dcdiag and various other utilities, it tells us that exceptions should be made to the firewall, equally I ran a DNS query on the servers and this also reported multiple errors
I wondering if any of you out there can help me with this, or at the very least rule out the UTM and RED device as being the issue, I don't have exhaustive knowledge of these devices and I simply don't know what I should be looking at to start the troubleshooting
Many thanks! [[:)]]
