Dual wan + Failover posible problem with gateway monitor (Dpinger)

Guest

Hi, my problem is to try dual wan with failover.

I have 2 Wan conections (different ISP) and one Lan, Is the typical dual wan + failover scenario.

wan 1 –> dhcp (WAN_DHCP) (use gateway x.x.0.30)
wan 2 --> static (GW_OPT1) (use gateway x.x.0.29)

Problem with gateways monitoring images:

both wans activated:

after deactivate Wan 1:

after reboot Dpinger with Wan 1 deactivate:

after activate Wan 1

at the end deactivate Wan 2:

As you can see, when I deactivate Wan 2, still online, only get offline when Wan 1 get offline, and when I activated Wan 1 automatically Wan 2 get online even if it is deactivate. This is my problem.

both gateways have the same Rtt but when I ping separately have different ms, a difference between 10-20ms

I using VirtualBox with PfSense 2.3-RELEASE (amd64) built on Mon Apr 11 18:10:34 CDT 2016 FreeBSD 10.3-RELEASE

My gateway group for failover (Packet loss or high latency):

Lan rule - Firewall:

I also have marked –> System / Advanced / Miscellaneous / LB / Default gateway switching / Enable default gateway switching

If someone happens the same or a similar problem I would appreciate any possible help.
Greeting and good morning.

your failover group has both on TIER1 ==> thats loadbalancing, not failover

also find it odd that the ip "the last" 2 bytes of your wan interfaces happen to be ending the same. this is unusual if there are 2 isps involved.
Are you positive that both wan interfaces are on a different subnet & their gateways are not the same?

Right, only I had config one group of gateways for the loadbalancing, now I have two more groups for failover where wan 1 has tier 1 and wan 2 has tier 2 & vice versa and also I add the rules on the firewall.

Maybe the problem may come from the subnet settings.
I have both Wans in the same subnet x.x.0.1/24

Wan 1 use dhcp with gateway x.x.0.30 and Wan 2 only use static ips in a little range into the same subnet with gateway x.x.0.29.

So two network interfaces with the same subnet.

Fail.

need to change x.x.y.x change y not the last x

I will try to change and reconfig my network and I will try again with pfsense.

Thanks to all! :)
