Internet User To Access Openfire Server

Hi,

Need your help.

Is configuration below works?, and how will I configure the client side (Spark)

XMPP Server Name : SERVER1

IP Address : 192.168.1.33

External IP add provided by DSL : 112.x.x.x

I just configure port forwarding on my router, any access to 112.x.x.x:5222 will be forwarded to 192.168.1.33:5222

Internet user (Other location)

On client side, how will Spark be configured to access SERVER1?

Thanks a lot.

A
