Patch fixing the segfault and discarding packeds on interfaces without IP
I've retested it and found out how you run into this problem:
The tap0 interface you were using did not have any IP address configured.
I'll fix it and forward the patch upstream, but this is a misconfiguration:
Both, the interface to the server and the interface to the client need IPs.
For example:
eth0: 192.168.0.1/24 -- interface to the dhcp-server (192.168.0.254)
tap0: 192.168.1.1/24 -- interface to the dhcp-client(s)
The /etc/sysconfig/dhcrelay configuration for this scenario is:
DHCRELAY_INTERFACES="tap0 eth0"
DHCRELAY_SERVERS="192.168.0.254"
on the command line it is:
/usr/sbin/dhcrelay -i tap0 -i eth0 192.168.0.254
