I just finished setup of Openfire 3.8.1 on Ubuntu Server 12.10 using Spark 2.6.3. I configured the server name as the internal ip. I configured WAN access using one of our static ip’s on our Astaro ASG 220 (have DNAT and Full Nat). All is working well on LAN using internal ip and external ip. External ip does not work on WAN. I am logging in with account ‘username’, port 5222 and server = external ip. My first guess is that the firewall is blocking, but the configuration looks right.
