[Symptoms]

I've been investigating an issue on OPNsense 26.7 where the WAN interface obtains a DHCP lease successfully and the associated gateway appears online, but the firewall does not install an IPv4 default route after boot.

Symptoms

• WAN interface is configured via DHCP.
• DHCP lease is acquired successfully.
• Gateway status shows the WAN gateway as online.
• No IPv4 default route exists in the routing table after startup.
• As a result, outbound Internet connectivity does not work.
• Gateway monitoring continues to report the gateway as online despite the missing default route.

Diagnosis

Immediately after boot:

• WAN interface has a valid DHCP address.
• Gateway object exists and is reported as online.
• Routing table does not contain a default IPv4 route (0.0.0.0/0).

Running the following command manually restores normal operation:
configctl interface routes configure

After executing the command:

• The default IPv4 route is installed.
• Internet connectivity is restored immediately.
• No further intervention is required until the next reboot.

#After reboot
netstat -rn4 | grep default
# no output

# Fix
configctl interface routes configure
 
# Afterwards
netstat -rn4 | grep default
default 83.217.167.129 UGS igb0


Has anyone seen a similar problem or have any further information, please?

Is the network interface for re0 working?

The device seems to be mostly working okay, but crashes intermittently with similar errors. Enabling IDS triggers the same errors.

If not, I am curious what version is your driver?

I've checked the logs and found:
re0: version:1.96.04
re1: version:1.96.04

Run and post the output of:

Output from strings /boot/kernel/if_re.ko is https://pastebin.com/iEyGTWk3

The cards are being identified by FreeBDS as:

device     = 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller'

OPNsense 21.1.1-amd64. Realtek NICs.

I'm consistently seeing the errors below at boot right after the login prompt appears:

eastpect[6925]   nm1::re0^: permanently promiscuous mode enabled

Can anyone give my any pointers for a fix please?
