Trouble with pfsync setup (netmask/32)

[Maxime Rey]

Hi,
I'm testing OPNSense to replace my actual firewalls (not the one connected to the internet but between my public network and internals networks).

I have some trouble with pfsync setup.

Master interfaces configuration :

WAN : 84.XX.YY.ZZ/26

LAN : 172.16.10.110/24 (GUI access)

INTERCONNECTION : 10.0.0.1/16

I configured Carp and PFsync on my master and created one interface on both firewall for the interconnection.
And after the reboot (mandatory to enable the config), I lost my GUI access and the INTERCONNECTION interface disappeared. Moreover the LAN netmask change from /24 to /32.

I tried to reconfigure the LAN interface using the OPNsense CLI but the netmask is always ignore  .

Start



Config



End



PS : No IP problem with my slave firewall

Any idea ?  ???
