Hi all !
I did an upgrade this afternoon for a previous version from opnsense 22.7.11_1 -> 23.1_7.
This upgrade was done in two steps :
opnsense upgraded: 22.7.11_1 -> 23.1_6
opnsense upgraded: 23.1_6 -> 23.1.7_3
I'm not sure that that point, but it seems that we lost the WAN netmask from /24 to /32 after upgrade :-(
OPNSense was claiming a gateway 100% lost packet, the cellular router was OK, o dropped packets from itself.
I check at the Gateways settings, tried a modification for the Monitor IP and OPNSense told the network range ( /24) wasn't relying the WAN interface
I did a check for the WAN settings, and the IP V4 address was /32 instead of /24. Once changed to /24, situation came back to nominal.
Did a such behaviour was seen in the past ?
Is it a known bug ?
Everything was OK before the upgrade.
Thanks a lot for your opinion.
PS : No VLANs, no Virtual Interface, just a very easy setup with a 4 x GB I211 Gigabit Network / Core i3-4010U CPU @ 1.70GHz
Is this a static IPv4 setup? It probably tried to auto-fix before and now that's only possible for DHCP when the ISP gives a far gateway.
So now you have the right setup for your situation ;)
Cheers,
