These type of tools tend to fall apart when you try to monitor a WAN, since traversing NAT firewalls break the SNMP.

However, the net-snmp package has the ability to use different ports, allowing one to use port forwarding on a firewall to map all the devices behind it.

A good project to look at for monitoring a WAN is Zabbix: <a href="http://www.zabbix.com/" title="zabbix.com">http://www.zabbix.com/</a zabbix.com>

Easy to set up, alsmost in the Just Works category.
