Astonia 3 Networking Details

[Detomah]

Auto Updater
The auto-updater is the first part of the game to access the net. If the primary connection is chosen, it will try to connect via TCP to 195.90.31.33:6214. If this connection fails it will automatically revert to the backup connection.
The backup connection will try to reach the update server via TCP at 195.50.166.6:6214. Older clients (which haven't been updated for a long time) will use 195.50.130.8:6214 if backup is chosen.

Game Client
The next network access is done by the actual game client. If the primary connection is chosen, it will try to connect via TCP to one of the hosts in the subnet 195.90.31.32/28 (ie. 195.90.31.32 to 195.90.31.47) to one of the ports in the range 5556 to 5570.
The backup connection will try the subnet 195.50.166.0/29 (ie. 195.50.166.0 to 195.50.166.7) instead.

Website
The website is at 195.90.31.33 and at 195.50.130.8 (port 80 for http and port 443 for https). The name server entries of www.astonia.com and www.intent-software.com will point to the one deemed more stable.

Firewall Config
A recommended firewall configuration would consist of:

allow outgoing tcp to 195.90.31.32/28 to ports 5556 to 5570 and port 6214
allow outgoing tcp to 195.50.166.0/29 to ports 5556 to 5570 and port 6214
allow outgoing tcp to 195.50.130.8/32 to ports 5556 to 5570 and port 6214

This configuration assumes that return packets and web access are already allowed (which is almost always the case).
