linksys ip

I am unexplored to Untangle and am struggling getting the AD Connector setup and unceasing.
My network consists of:
Internet > Linksys BEFSX41 Router > UT > LAN (SBS 2003 R2).
Linksys router IP: 192.168.0.1
UT IP: 192.168.0.102
LAN IP: 192.168.16.2
I tried to setup the AD Connector from the SBS building, but it continually fails no move what settings I whack at. as usual Our FQDN is kok.lan (not local), but no move what I whack at, it fails.
I then went to the UT clout and tried to ping SBS.

I tried creating rules in ISA to permit the above (although nothing was getting blocked from UT), to fails. as usual It failed. as usual
My qualm is that the UT clout does not exigency the lodge a get aside settings to luxuriate in with SBS (different networks).
I could unqualifiedly run out of some advice on how to become ear-splitting on a alight UT to luxuriate in with my SBS clout so that I can successfully setup AD Connector.
