ipv6 gateway bug

« on: October 17, 2023, 05:48:33 pm »

If gateway monitoring is active for an ipv6 gateway with an ula address, then the gateway or the service must be restarted after the opnsense restart.

If gateway monitoring is disabled, then the service or gateway starts normally.
The problem occurs only with the dpinger.

OPNsense 23.7.6-amd64
FreeBSD 13.2-RELEASE-p3
OpenSSL 1.1.1w 11 Sep 2023

i want all services to run with wirespeed and therefore run this dedicated hardware configuration:

AMD Ryzen 7 9700x
ASUS Pro B650M-CT-CSM
64GB DDR5 ECC (2x KSM56E46BD8KM-32HA)
Intel XL710-BM1
Intel i350-T4
2x SSD with ZFS mirror
PiKVM for remote maintenance

In had a similar issue that could be related. In the referenced github there's a workaround.
Issue seems to arise on statically assigned IPv6 adresses.

ULA is a bit of an issue if you want to use a monitor address that is a GUA...
