APF + interface eth0 is routed to a network

[vinc_dc43]

I am trying to get APF setup on a server and I keep hitting the following error:

"could not verify that interface eth0 is routed to a network, aborting."

I changed the conf file to check on eth1, as this is the external interface.

Anyone have any ideas?

did you restart apf after changing the conf file?

service apf restart

otherwise it is still running with the old config values
