Cannot see server under SLP

At the central site, I setup a DA on a server, a MA on a router connecting the private & the public network, the MA command is “scmd /am /nat;public IP;public IP mask;NAT realm;private network number”. At the remote site, I setup a CMD server with an entry pointing to the central site’s DA in slp.cfg & the preferred MA set to the central site’s MA. Using the “display servers” command, I can see the remote servers at the central site’s MA server but I can’t see the central site’s server at the remote site’s CMD server. I can see the central site’s server name appended to services:bindery.novell using the command “display slp services”. What;s missing from my setup ? Thanks.
