Setup for 2-pfsense loadbalance/failover?
-
We have an installation with 2 3-port PFsense hardware boxes, connected with both PPPoE links to the same ISP - the setup looks like this.
WAN1 WAN2
| |
–--------- sync (Opt1) ------------
|pfsense1 |-----------------| pfsense2 |
----------- ------------
| |
LAN1 LAN2
| |
---+---------------------------+------Both pfSense routers are using PPPoE to the ADSL wan via bridge-mode ADSL modems. I can figure out how to do failover from left to right using CARP (tested in VMware) but
is there any tutorial/guide on how to setup CARP failover and inwards & outwards round-robin load balancing? Can it be done with this type of setup or would we need pfSense hardware boxes each with 2 WAN links, a LAN link and a Sync(Opt1) link for CARP? As pfSense only supports 1 PPPoE link per instance, this would mean some changes to the modems as well if each pfSense box had to support 2 WAN links.Any help or pointers to guides for this would be appreciated.
