Using a DHCP server for two subnets

Has anyone successfully used one DHCP to serve hosts on two subnets?

 

If anyone can share their dhcpd.conf syntax, I would appreciate.  I
think I have it correct because the DHCP server will issue:

 

dhcpd: DHCPDISCOVER......................................

dhcpd: DHCPOFFER..........................................

dhcpd: DHCPREQUEST......................................
dhcpd: DHCPACK...............................................

 

But then I immediately receive:

 

in.tftpd[4254]: RRQ from 10.225.248.1 filename pxelinux.0

in.tftpd[4254]: tftpd: read: Connection refused

 

I am not sure if it is a dhcpd.conf configuration problem or not.  My
switch has "port fast" enabled.  I can Kickstart servers with no problem
but when I introduce a second subnet into my dhcpd, tftp fails.

 

How anyone ever seen this?

 

I had tried this a few months ago but was never able to get around it
but I have a need to revisit this now and get it working.

 

Thanks.
