Spark Conection over VPN does not work with Openfire under Linux

I have two Openfire Server instaledd on my network :

server 1 - installed on a windows 2003 machine with openfire default DB

server 2 - installed on a centos 5.3 machine with a mysql DB

I have a Home location and a Remote location conected through a vpn; the computers at remote location act as they would be in the local LAN; the take their IP throught DHCP; can browse the network…etc

At remote location if I try to connect spark at server 1 it works perfectly, but if i try to connect at server 2 i get the message Invalid Username or Password ?

What can be the problem ?

i installed openfire on centos with embeded DB - still cannot conect to chat server ; on centos machine firewall is down; is visible - i can ping in to it; has the necesary ports opened - visible at a nmap scan

PS Both servers are at home location; Strange is that from remote location I can connect to the openfire installed on Windows and I cant on the openfire installed on Linux

if I listen on the port 5222 this is what i get :

[root@localhost ~]# tcpdump port 5222
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
