Hi

We have a little problem with the Option 78 and a third-party Firewall DHCP.
All clients never receive a SLP IP address.

We think the problem is the Novell Client 4.91SP5 and not the DHCP
server, because in the packet sniffer I can see, that the Novell Client only
request the Option 81 and never Option 78.

In the client settigs we have the parameter "Use DHCP for SLP" on and I
think that should be enough for a request the Options 78/79

Where else could be the problem on the client side?
We don't have ZenWorks installed.

The slpinfo /all output looks like this on the clients:
