Problems with fresh installation - no route to internet

[tramhappert]

Hi,

Version installed: 24.1_1

I tired a fresh installation with the following settings, done with the wizard:
  - WAN (STATIC IP - /28 subnet ipv4)
  - LAN (STATIC IP - no dhcp)

The opnsense itself can check the installation and can check for updates.
From LAN i can PING the WAN adress of the opnsense, but i can not ping the gateway of my public /28 WAN subnet. That one should work, because it is direcly connected.

Thats just with the fresh installatin. I could fix that with setting a manual already installed IPv4 upstram gateway. That wasn't done with the wizard. The wizard let it on "Auto-detect". Then i can PING the Gateway of my WAN subnet.

But then there is the problem with no route to the internet. Sometimes it is working, when i set it to a dedicated IPv4 Upstream Gateway but not always. But it just works sometimes, with some reboots and when i wait some time.

On the routing table there is no "0.0.0.0/0" route too.

Is that just a problem with the new version? Why is there also no default route on the routing table set?

Regards
