I'm in the process of setting up a remote office and I need to be able to login to our eDir tree form the remote office. The link is via a point-to-point SSL tunnel over public internet. The problem is no matter what i do, I always get the "tree not found". I have SLP configure as follows:

SRV1 (DA server. IP 192.168.170.1) on local LAN:
net.slp.DAAddresses =
net.slp.isda = true
net.slp.isBroadcastOnly = false
net.slp.useScopes = SCSLLC

SRV2 also on local LAN:
net.slp.isda = false
net.slp.DAAddresses = 192.168.170.1
net.slp.isBroadcastOnly = false
net.slp.useScopes = SCSLLC

SRV3 in a DMZ zone:
net.slp.isda = false
net.slp.DAAddresses = 192.168.170.1
net.slp.useScopes = SCSLLC
net.slp.isBroadcastOnly = false

I have the remote computers configured with correct scope and pointing to the DA server.

What could be the problem?
