Hello,
I have installed TMG with 3 NICs such as ISP1, ISP2 and Internal
I configured the ISP1 and ISP2 interfaces with IP addresses and default gateways and
configured internal NIC with IP address, but Default Gateway.
I installed DNS service on TMG and configured the forwarders pointing to ISP DNS servers.
Finally Internal NIC DNS configuration
Primary : 127.0.0.1
Alternative: Internal AD DNS servers
Configured persistent routes
=============================================================Persistent Routes:
Network Address Netmask Gateway Address Metric
10.0.0.0 255.0.0.0 10.1.2.1 1 ( Internal LAN)
1.1.1.1 255.255.255.255 192.168.5.1 2 ( ISP1 DNS Server)
2.2.2.2 255.255.255.255 192.168.4.2 3 ( ISP2 DNS Server)
0.0.0.0 0.0.0.0 192.168.4.2 Default
0.0.0.0 0.0.0.0 192.168.5.1 Default
Now I am trying to join the TMG server to domain but failed. Error saying that cannot resolve domain name
I would highly appreciate any help.
Thanks
