I read a bit through the KEA mailing list and this looks related:

https://lists.isc.org/pipermail/kea-users/2026-March/006027.html

Yes, I do see this log:
DHCP4 failed to open service sockets — the maximum number of attempts (0) was exhausted without success.

After upgrading to OPNsense 26.1.6

Are you from the future ?

;)


/Could not resist... ^_^

😂

There should be no need for Kea to run on a WireGuard interface. Did you try deselecting  it in the settings ?

The re0 interface is configured as LAN

Hi,

After upgrading to OPNsense 26.1.6, I'm experiencing issues where Kea DHCPv4 does not start properly and clients fail to obtain IP addresses.

**Environment:**

* OPNsense 26.1.6
* LAN interface: re0 (192.168.50.1/24)
* AP: TP-Link (bridge mode, no DHCP)
* DHCP server: Kea DHCPv4

This setup was previously running ISC DHCPd without any issues.

---

**Observed behavior:**

From the logs, it looks like Kea attempts to start while the LAN interface is not yet up:

```
DHCPSRV_OPEN_SOCKET_FAIL failed to open socket: the interface re0 is not running
DHCP4_OPEN_SOCKETS_FAILED maximum number of open service sockets attempts: 0, has been exhausted without success
```

Shortly after that, the interface comes up:

```
re0: link state changed to UP
```

Thanks.

After upgrading to OPNsense 26, the DHCPv6 client repeatedly sends Solicit requests on PPPoE even after successfully obtaining an IPv6 prefix delegation (PD).

The logs show advertise contains NoAddrsAvail status, and this behavior was not present in earlier versions.

Hello everyone,
How to view pd lease information in opnsense?
There is no relevant information in the log.
Thanks

The wan port originally had a link-local address that was different from the lan port. The problem was that it added a link-local address that was the same as the lan port.

After webui interfaces-overviews wan 'Reload', wan's ipv6 has an additional address that is the same as the lan Link-local address.
The same situation is also seen when using the ifconfig command to check the PPPoE interface. Restarting the system can back to normal.

Mybe the AP will not respond to http/https (?) requests from foreign subnets. Some devices (or the desired service of those) have an option to explicity permit those requests.

I compared openwrt and found that this problem can be solved by setting snat
firewall - nat - outbound:
Select - Hybrid outbound NAT rule generation
Add rule - interface: lan, tcp/ip: ipv4, source address: wg net, destination address: lan net, translation/target: lan address

#!/bin/sh

sh /etc/rc.local

In addition, the interface -> wan -> DHCPv6 client configuration -> Prefix delegation size must be accurate, such as 60 instead of 64, otherwise the prefix in the RA received by the client is 60 bits instead of 64 bits, so the client cannot use slaac mode to generate ipv6
