If you have used the Online User Manual link on the main menu of your Internet Gate, or any other online user manual links in its web GUI then you automatically see this documentation adapted to your unit: features not supported by your unit are marked with warning messages.

If you have browsed to this documentation from the Internet (not using a link on your Internet Gate's web GUI) then you see a generic description of the Internet Gate here, with all features available in any Internet Gate model described.

Older models

Internet Gate currently has 5 Ethernet ports at its back panel. A previous model of it had just 4 Ethernet ports (it had no ET0 port). All descriptions of this manual is applicable to that model too, except pages describing using port ET0 as WAN port. (That model used port ET4 as optional Ethernet WAN port.)

Older models of Internet Gate, called IX68, IX67 and IX66 have many basic features common with the current model of Internet Gate, thus some of the generic basic descriptions might be valid for those models too. They do however lack most of the more advanced features of the Internet Gate.
For those models please refer to the online manual at
