Hello, I've got a router running woody and a 2.4.17 kernel that has to respond to DHCP requests it gets relayed from another router on the same subnet. I've configured everything (as far as I can tell) according to the readmes, and the server is running. It's just not responding to relayed queries, without even logging any errors. Does anyone have any suggestions? I've tried everything I can think of, which probably means there's some small detail that's totally obvious that I've overlooked and will keep overlooking until someone points me at it. I've attached the config file and part of a tcpdump output below; IP adresses were edited for security reasons. The situation: 'server' is the actual dhcp server with three network cards. eth0 connects to 192.168.10.0 with netmask 255.255.255.252, and traffic to 192.168.11.0 and 192.168.12.0 is routed via 192.168.10.1 eth1 connects to 10.10.20.1 and through that to the outside world. eth2 connects to the backup server which has to take over if this one fails. 'relay' is at 192.168.11.1 and sends relay queries to 'server' at 192.168.10.2. These come in over eth0.
