Routing table corruption after reboot. *PROBLEM FOUND/SOLVED*

[mrzaz]

Hello,

I have an issue that has been going on now for some time that is very anoying and still after 22.7.6 upgrade persists.

BACKGROUND:
I have 4 IPsec tunnels (one standard and 3 VTI) and a OpenVPN Server configured

PROBLEM:
What happens is that every time I reboot the opnsense, two of the static routes configured gets corrupted and selects a different gateway. Happens every time I reboot. If I remove and set them up again the routing table becomes correct and routing starts working OK.

After REBOOT
Destination             Gateway              Flags    Use     MTU     Netif         Netif(name)
192.168.10.0/24     192.168.121.2   UGS     NaN     1500   ovpns1     OVPN_SERVER
192.168.20.0/24     192.168.121.2   UGS     NaN     1500   ovpns1     OVPN_SERVER

After reconfigure 192.168.10.0 and 192.168.20.0
Destination             Gateway              Flags    Use     MTU     Netif         Netif(name)
192.168.10.0/24     link#8                 US        NaN     1400   ipsec1     HENRIK_VTI
192.168.20.0/24     link#9                 US        NaN     1400   ipsec3     HENRIK_MAMMAPAPPA_DIREKT

Have tried all sorts of things but problem still persists and ONLY one these two routes...
Feel it is a bug lurking...

Has anyone else seen this problem and could someone at opnsense have a look.
I have attached some screenshots and logfiles.

Contact me with pm for more screenshots, logs and I could include the config.xml as well.

UPDATE:
I have now found the culprit.

I had a by misstake defined a bunch of networks in OpenVPN Server config "IPv4 Remote Network" which caused it to highjack these nets towards the ovpns1 interface instead of the one I had defined in the routing table. Problem is now solved...
