Hi Security World,

Title: Enabling DHCP Relay for DMZ Segments
Author: Thomas Shinder
Summary: In an earlier article I discussed how you can configure the DHCP Relay Agent on the ISA firewall to deliver DHCP options to VPN clients. The VPN client situation is somewhat unique, in that the RRAS server obtains IP addresses on behalf of the VPN clients, and then when the VPN clients connect to the ISA firewall’s VPN server component, the RRAS service provides the VPN clients with an IP address. The RRAS service never sends the VPN client DHCP options. That is why you need a DHCP Relay Agent on the ISA firewall. The DHCP Relay Agent forwards the DHCP messages to a DHCP server on the corporate network.
