subnet mask 255.255.0.0

Hello,

I need plenty of ip address so I decided to use the subnet mask
255.255.0.0 (overkill I know !)

My servers all have ip range from 192.168.1.x to 192.168.1.xx all with
mask 255.255.0.0

My bm server has 2 nics..one with public address bound and the other with
public address of 192.168.1.3 mask 255.255.0.0

I presently have Dhcp server (3.13) issuing address on 192.168.1.50 to
192.168.1.250 and 192.168.2.1 to 192.168.2.250...

Address are issuing fine but clients that receive address from
192.168.2.x cannot access the internet. Default gateway is 192.168.1.3

BM server has static default route set, and several secondary ip address
which NAT to mail and web servers.

Do I have to bind 192.168.2.3 (for example) to the same nic as
192.168.1.3 or can I get things to work another way.

Any Ideas or comments.

Thankyou

Warren
