[RESOLVE] Strange behavior 2 opnsense same subnet

[Georges]

Hello,
I got 2 Opnsense Admin interace in the same subnet.
.1 and .2
a 3rd firewall in .3.
Each 2 first opnsense send telegraf information to another VM passing throught the .3.
So .1 to VM by .3
And .2 to VM by .3
(With gateway and route configure on both opnsense firewall)
I got this behavior
On the .1 i see the blocked request from the .2 at destination to the VM
And same on the .2, i see the .1 request to the VM blocked...
How.. is this even possible? 0.0...
I and it's really block, on the .3 with tcpdump i can see the request.
I am confuse. Did anyone already get this strange behavior?

Ok found it.
the .1 and .2 have 2 gateway declare .1 and .3 for the .2 and the .2 and .3 for the .1.
With the same priority: 255 xD.
This was my falire, i reduce byt 1 the most important between both and make sure my master gateway get a priority with a lower number thant everybody and that's it.
sorry.
