We aren't sure if this is a server side configuration issue or a router/firewall issue.

but this is the log error we are seeing.

Oct 26 10:02:25 xserv1 bootpd[9836]: can't open /etc/bootptab
Oct 26 10:02:25 xserv1 bootpd[9836]: server name xserv1.xxx.xxx.xxx

Netboot/DHCP filtering is OFF

The /etc/bootptab file does not exist.

(actual IP's changed to protect the innocent!)

bootptab should contain mac addresses of the hosts your trying to net-boot.
Howerver nice Apple Gui tools are supposed to write to it without problems and fill it in for you.

So the only thing I could think of is they cannot, a suggested solution with 10.5 netboot clients was to

sudo touch /bin/bootptab

to create a blank file, that bootp can read, and reload the NetBoot service.

Thank you DJ. that seems to have put the bootptab file in place, and changes the log.

Any thoughts on the "Failed to convert 'router' Invalid IP"?

seems like a missing default router/default gateway entry from one of the subnets defined in NetBoot.

Sorry check the Subnet settings in DHCP in Server Administrator. I believe it gets it's router entry from there.
