Salaam, How can I connect an additional ADSL line to current LAN, where I want to use one DHCP Server(Windows Server 2003), and specified one ADSL line for some users and the other line for others, where all users connected to a single switch.

I ask that because i am not familiar with other brands.

If yes, then you create a vlan for each segment. You put a IP helper address for each vlan configuration pointing to your DHCP server. You configure both segment in your DHCP server. The IP helper address will advise the DHCP server on which segment it wants the IP address it is asking for.

thank GL, I have a Cisco switch 2950.

I will configure my Windows 2003 Server as DC, DNS, DHCP server, LAN-to-LAN router, and configure the main NIC to be ICS.

Does 2950 switch have function DHCP relay ?
if not,Is there ability to make the same DHCP Server as DHCP Relay Agent by configure the other NIC to accept the DHCP requests then forwarding it to DHCP Server (main NIC interface), and will give the correct IPs to PCs in the Correct Subnet.

Best Regards,
MAH
