[TriLUG] dhcrelay troubles

[chris at bullocksbarn.com]

So are you saying that for all of the subnets you must have an alias on
the dhcp server.  I have been struggling with relaying dhcp for a while
now without a fix.  I have 5 subnets seperated by a router running
dhcrelay.  By what you are saying, I have to put an alias on my dhcp
server to serve up dhcp, is this correct?
