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.
Firewall Config
RH 7.3
IPTables v1.2.5
ETH0 (Internet)
ETH1 (LAN1)
ETH2 (LAN2)
