New VLan problem

[David Anderson78]

Attached is how our current network is setup ready for the new VOIP phones. DHCP works fine for handing out 172 and 192 addresses based on the vlan being routed through.

The only problem is with our email server. If we use 172.16.1.10 on the Domain controller as the default gateway the email server sends out emails fine, but DHCP will not hand out 192 ips to the pc's on VLan 200
If we use 172.16.1.20 on the Domain controller as the default gateway the email server does not send out emails, but DHCP will then hand out 192 ips to the pc's on VLan 200.

This is madness. All help greatly received

Fixed it.

Added DHCP DG as 172.16.1.10
and added "route -p add 192.168.0.0 mask 255.255.0.0 172.16.1.20" via cmd on the DHCP server.

Thanks to all the helped
