gateway-problem since 22.1

[bbkitz]

The following input errors were detected:

    Cannot add IPv4 Gateway Address because no IPv4 address could be found on the interface.
----------------------------------------------------------------------------------------------------------
worked ok until 21.7.8, on two opnsenses, two others with no problem
now strange messages:
1. "gateway offline" in dashboard and System / Gateways / Single, dpinger with red marker on dashboard
2. routing, vpn etc. all works ok !!!
3. monitoring on/off or anything else changing in Gateways/Single not possible - see error-message in lines 1,2
4. deleting gateway is possible, but no new gateway to install - see error-message in lines 1,2

since my post on 18.2.2022 many forum-users read the post but there was no reaction in the forum, so I tried some more variants

My hardware: APU4d4, SSD 16GB, opnsense-nano 64bit
ISP: 5 IP's x.y.48.194,195,196,197,198, WAN-Interface: x.y.48.194/29, Gateway: x.y.48.193

Installed opnsense 21.7.1
configuration restored from system/configuration/backup -> opnsense worked like ever, gateway online, routing ok.
Updated to 21.7.8 (per GUI) -> opnsense worked like ever, gateway online, routing ok, gatewaysettings changeable
Updated t0 22.1 (per GUI) -> opnsense routing worked, gateway offline, gatewaysettings not changeable with error-message:
"Cannot add IPv4 Gateway Address because no IPv4 address could be found on the interface."

Since dpinger is not working I cannot attach a log, because there is no one.

Looks like a (new) problem with the IP-range, even when far-gateway is set?

opnsense is working at the moment, but whenever I want to change anything with the gateway it is not possible - that means no future?
Has no other user such a problem? Can anyone help me?

You probably have overlapping DNS routes, gateway monitors and upstream DNS servers from your ISP.

ALL create host routes and if you have multi-wan and these are out of order it will break monitoring.

thank you very much franco, that was a good tip!

in  Interfaces/Virtual IPs/Status/pfSync nodes  I found the gateway x.y.48.193 three times with three different IDs

Now: how to get rid of the unnecessary two?
