How would one configure a DHCP Pool on a 3750 for a network that is not directly connected to the switch?

Configure the DHCP pool on the 3750 as you would normally. The connected devices between the 3750 and the clients need to have an IP helper set. Can you post a network topology?

When I configure the 3750 with dhcp pools with address space within hte subnet of what is defined in the vlan interface the DHCP works. When i configure a pool for 10.3.3.0 which does not have a vlan interface on the 3750 the 3750 does not hand out ip addresses to the Remote VPN user DHCP client. Topology attahced
