Auto dialing PPPoE interface in CARP failover
I have a Pfsense 2.0 RC installed on a VM with 2 WAN interface configured as PPPoE. Is it possible to configure a 2nd Pfsense instance using CARP which act as a fail over, and also to auto dial the PPPoE in the standby instance when the first pfsense fail ? I did find the XMLRPC Sync option that would sync a lot of settings, but will the standby pfsense instance be able to dial PPPoE on WAN interface when the fail over is detected ?
You can only properly do CARP failover with static IP WANs, it wouldn't fail over properly and keep connections alive with a PPPoE WAN.
Also I don't believe the second WAN can be on-demand when used with multi-wan. pfSense constantly pings the gateways of all WANs to ensure they are usable, and there isn't a mechanism currently to handle on being left down until needed. This is in the works, though, because it would be useful for 3G connections where bandwidth is expensive.
