Since the DGN2000 has no SNMP or any other mechanism for obtaining traffic information, I opted to "hack" something together via telnet. Since I use some scripting I'm afraid that this will only work on Zabbix servers that run on *nix with perl and expect installed.
The router needs to be flashed with the V1.1.8.0 - DGTeam Rev. 1018 (http://dgteam.netsons.org/) which adds telnet capabilities.
The main script is zabbix-dgn2000-cron.pl which should be added to cron every minute, with the first parameter being the hostname in zabbix that has the templates, and the second being the IP of the device that is being monitored.
The zabbix-dgn2000-expect.sh scripts has a hardcoded telnet password that needs to be changed to match the admin web console password.
