SBS2011 DNS for external FQDN
Posted on 2016-10-24
On our LAN we have:
a) PDC @ 192.168.1.1
b) Old TS 192.168.1.5
c) New TS 192.168.1.14
We use remote.ourdomain.com.au to access the old TS which worked well for both internal & external clients.
I wish to decommission the old TS and commission the new TS. Updated firewall to fwd port 3389 from 192.168.1.5 to 192.168.1.14, tested and works for me.
Problem: Now when internal users RDP to remote.ourdomain.com.au they go to the PDC?
I have checked the SBS DNS and under Forward Lookup Zones there is an entry for remote.ourdomain.com.au which has 3 entries:
1) SOA => pdc.ourdomain.local
2) NS => pdc.ourdomain.local
3) A => 192.168.1.1
a) Does the Forward Lookup Zone "remote.ourdomain.com.au" direct internal traffic to the A record?
b) To direct this traffic to the new TS do I need to only change the A record to 192.168.1.14?
c) Why did it work with the old TS @ 192.168.1.5 and now it points to 192.168.1.1?
