A Firewall can be installed on a specific port to reduce damage from attackers. Firewalls add an additional CPU cost to the port. Firewall experience is gained by absorbing damage from incoming attacks (one XP per damage point). Firewalls are one way a player can gain experience while offline.

Note: Firewalls offer no protection while your system is overheated.

Firewall Level

Your Firewall level determines which Firewalls you are allowed to purchase from the Main Game Store. There is no level restriction on installing a firewall, however. Buying a firewall from another player is a way to avoid the level restriction of the game store. Firewalls cannot be programmed by a player, but they are among the NPC drops.

Attack-back Firewalls

Whenever an attack-back Firewall is hit for damage, it deals damage back to the port which is attacking it.

Installing a Firewall

Firewalls are installed from within the Port Manager, as shown here (highlighted in green), by right-clicking on the Port under “Firewall”.

Firewalls and Watches

Unlike Applications, a Firewall is flexible with respect to its specified port. Certain Watches allow a player to switch a Firewall between various ports. Like an application, however, a Firewall cannot be uninstalled.
