A Complete CARP / Failover setup
-
http://doc.pfsense.org/index.php/Configuring_pfSense_Hardware_Redundancy_(CARP)
2 pfsense machines is fine.

thanks..
but this document doesn't say anything about having two ISPs though
how that works…do I need to have two WAN per each machine? so that means 4 NIC per each
-
CARP is not for two ISPs but as you fairly mentioned for hardware redundancy. For two ISPs you need LoadBalancer or BGP.
-
thanks…
ok, so what would I need to setup the loadBalancer? Do I need 1 NIC for pfsync, 1 for the switch and 2 for ISPs? so total of 4 NICs..correct?
-
does Pfsense supports BGP?
-
OpenBGPd is available as a package.
As for the NICs, you should have one more on each box than you would for a stand-alone system. This would be for a dedicated sync interface between the boxes. -
thanks
How is OpenBGPd? have you ever used it? does it work good?
and for the NIC, are you sure that need another one? 1 for syncing, 1 for switch, 2 for ISPs (two ISPs).. total 4 NICs…
Am I missing something here?

a) I haven't used it, so I can't comment on how well it works.
b) Yes, 2 WANs, LAN, and SYNC would be four interfaces in each. I generally just use a crossover cable for the SYNC. -
do you recommend any two-ports Network adapter? something that works with pfsense

I haven't ordered any recently, so I don't know if you can get these anymore. Generally Intel nics are supported, but there are sometimes problems with the newest chipsets. Anyway, I'm running these personally in several boxes, so I'm sure they work with pfSense.
Intel PWLA8492MT Dual 10/100/1000 PCI/PCI-X
Intel EXPI9402PTBLK Dual 10/100/1000 PCI-e
These may be the low-profile numbers, but IIRC, they came with both brackets.
If you don't need GB, check ebay for used dual-port Pro100 cards. -
Can you run Carp with only one public IP adress???
I have a minor dicussion with our IT expert, and he believes it will take 3 public IP adresses to run carp with 2 pfsense boxes….
What do you guys say about that???
-
Your IT expert is right. He is the expert after all.
(OpenBSD has CARPdev, which allows you to run a cluster with one public IP, but FreeBSD does not have this functionality yet) -
Super! I need to get more beer then…. :D :D
