Dual wan cluster setup.

[flamy]

Hello all, I'm trying to configure pfsense to act as a redundant firewall on a redundant link, so I have two servers if one goes out of commission the other takes over, and also I've got two separated links to the Internet, so if one link fails both servers switch to the other one. Everything is seen better on the graph attached(diagram.png), right now ignore DMZ I haven't configured it yet.

First I configure cluster failover, according to this - ftp://reflection.ncsa.uiuc.edu/pub/pfSense/tutorials/carp/carp-cluster-new.htm  except I add additional NAT rule for secondary WAN link(net_mapping.png), create static routes for DNS servers. Everything works at that point. Then I  configure load balancing service from Services -> Load balancing. Then I need to change outgoing Lan gateway from the default to load balancer, as soon as do that, virtual ip on the local network, that is used for cluster failover stops working, neither does web interface work on that address. I tried not changing Lan gateway, but without it failover doesn't work.  May be someone ran into situation like this before.

Any help appreciated.
