DHCP server not handing out IP addresses

[Ryan McCain]

I recently attempted to migrate DHCPD from SLES10 x86 to SLES10 s390x.  I have  a primary and secondary server.

Everything worked fine when DHCPD was running was on the x86 servers.  I've used tcpdump to verify that no DHCP requests are even hitting the SLES10 s390x servers.  I've turned off all software firewalls.  All DHCP helpers on the routers have been updated.  Also, when I take the config file from a SLES10 s390x server and move it to a SLES10 x86 server, it works fine on the SLES10 x86 server.

The version of DHCP on both platforms is dhcp-3.0.3-23.33.

Any ideas?  Is there something in the mainframe world that needs to be configured to allow in UDP traffic on port 67?

Thanks, 
Ryan
