My debian etch machine has two network interfaces.

Is it possible to use ddclient to update dns for two different interfaces?

eth0 - dynamic IP connected directly to the internet via a cable modem
eth1 - static IP connected to a router, connected to a second cable modem (pulling a dynamic IP)

I'd like ddclient to update the DNS at ZoneEdit as follows:

wan1.mydomain.com - Dynamic IP on eth0 (use=if, if=eth0)
wan2.mydomain.com - Dynamic IP on router (use=web)
lan1.mydomain.com - Static IP on eth1 (use=if, if=eth1)
