[Serusers] SER Running fine - Users Registered but can't see each other!!

Hi There everyone, I have a wierd one for you! I have SER 8-12.0 running on redhat 9 i386. MySQL and Ser MySQL are installed and working. Authentication works fine The problem is that none of my users can call each other (via X-lite) or see each other on Messenger! I have two Win 2000 client machines each running xlite and MS Messenger both registered okay. UL list shows the following (Numeric aor's are the XLite and Named aor are from Messenger) In this example both machines are behind the same NAT firewall but it's the same if I take on of the clients onto a seperate direct internet connection. Ser.cfg is below also Anyone seen this before? Thanks for your help! Darren [root@gandalf root]# serctl ul show Dumping all contacts may take long: are you sure you want to proceed?
