Pix 515
PIX OS 6.3
I have some remote access clients that are currently using a pool that is defined on the pix to get ip addresses. My coworker said that we need to use DHCP relays to have it forward the request to our internal DHCP server. He found some documentation that makes him believe this is possible. I tried to set it up and it did not work. I set up the dhcp relay as the cisco config guide said to and dhcpd was not running on our pix but it still used the predefined pool. I then removed the pool from our vpn configuration and the vpn stopped working and produced an error message in the log that said, failed to assign ip address from pool. I am thinking that dhcp relay is used for site to site vpns only, not remote access vpns and actually found a few articles stating that fact. He thinks I just don't know what I am doing

Anybody know if this is possible and if so, how to do it?
