All,
I am wondering if someone out
there would be so kind as to help me figure out why I cannot get DHCRELAY to
relay DHCP requests from one LAN segment to another LAN segment where a Windows
2000 DHCP server resides. I have verified that the requests are hitting the
DHCRELAY on 67/UDP and then the DHCRELAY is trying to send back out on ETH2
(LAN2 Segment) to the DHCP Server on LAN1, but there is nothing after that. I
have used Snort in sniffer mode and I can see UDP traffic on 68/UDP and 67/UDP
on LAN2, but I never see any on LAN1. So my guess is that for some reason it is
not routing through the firewall correctly. Any help would be greatly
appreciated.
