dhcrelay

Hi there

I'm wondering if anyone has made the dhcprelay program 'dhcrelay' run on a
redhat 6.0 system. It's running stock kernel and config.

I'm experiencing the following problem:

There are 2 networks, A & B.
eth0 is connected to network A. eth1 is connected to network B.

There is a dhcp server running on an NT box on Network A (nt isn't the
problem :)

There is a linux router passing traffic without a problem from network A to
B
There is a machine on network B trying to get IP information from the dhcp
server on network A.

The linux router can see both machines (ping test). dhcrelay was started
using the following syntax:

# dhcrelay <ip address of dhcp server on network A>

the following output is produced:
Listening on Socket/eth0/unattached
Sending on   Socket/eth0/unattached
Listening on Socket/eth1/unattached
Sending on   Socket/eth1/unattached


netstat -an --udp shows this line (amongst other things):
Proto Recv-Q Send-Q Local Address           Foreign Address         State

udp        0      0 0.0.0.0:67              0.0.0.0:*                  


Soo.. the daemon is listening on the correct port. With tcpdump you can see
when the machine on network B sends a dhcp request out it arrives on eth1,
but nothing ever leaves out eth0

Any ideas anyone?

Thanks
