Blocked addresses to internet?

[jmair]

I have my address range as 10.1.x.x for my DHCP. Machines assigned and ip of 10.1.1.x can access the internet but anything with 10.1.2.x can not.

I've changed the subnet to 255.255.0.0 on the DNS, DHCP server (NICs Static IP Configuration) and the Firewall/Gateway.

What am I missing? Any suggestions?

have you added the subnet to reverse lookup zones in dns?

Does the router/firewall have an updated route back for the internal addresses? It probably already has a default gateway for it's external port and the static route back to the internal network is still 255.255.255.0

Yes. I believe it's fine there. The dns/dhcp server is behind the firewall with all of our client machines, and all client machines work fine internally.

Perfect. That's what it was. Always a good place to ask questions,... Thanks!
