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.
