Problem with high availability and lan traffic between host

[johjoh]

Hello, I've configured 2 OPNsense in HA with multiple VIP Carp.
The NAT work correctly and I can explore internet.
When I reboot the master, the slave work flawlessly.
VIP LAN CARP 192.168.1.1/16
My problem is between client host on the LAN network, for example:
From 192.168.100.1 I can ping 192.168.1.10
From 192.168.100.1 I can't explore the https page on 192.168.1.10
From 192.168.100.1 I can't explore the shared folders on 192.168.1.10
Any suggestion? Can be the managed switch, I need to reboot it?
If I reconnect the original firewall (obsolete, I want to change) https, shared folder, etc work without any problem.

Ok I have discovered something.
VIP LAN CARP 192.168.1.1/16
OPNsense 1 192.168.1.2/16
OPNsense 2 192.168.1.3/16
LAN 192.168.0.0/16

If my notebook have ip 192.168.1.x everything work
If my notebook have others IP for example 192.168.100.x, 192.169.200.x it don't work

Can be a bug in VIP CARP Subnet 192.168.1.1/16?
