[WORKAROUND] RADVD Broken in 17.1.r1

[will]

Hi,

Since upgrading last night to 17.1.r1 it seems that I no longer have working IPv6 on my LAN.

WAN Side is fine (PPPoE / DHCPv6) and if I ping from the OPNsense box itself from both LAN and WAN interfaces traffic flows just fine, similarly if i configure a host in my LAN with a static IPv6 address it also works so the underlying connectivity is not a problem.

Running tcpdump on the OPNsense box I can see router solicitations arriving from my clients both on my wired and wireless LANs but I do not see the OPNsense box sending any router advertisements.   DHCPv6 is also running but as my clients are mostly OS X / iOS at home it's hard to test if that is really working too.

Anybody else seeing the same behaviour?

Shawn reported a similar thing. Try the older radvd package:

# pkg add -f https://pkg.opnsense.org/FreeBSD:11:amd64/17.1/MINT/17.1.b/OpenSSL/All/radvd-1.15.txz


Cheers,

Hi Franco,

Just to confirm that applying the older version and rebooting has fixed both the RADVD and DHCPD6 issues I was seeing- my hosts now how IPv6 again and I can see RAs coming from the OPNsense box.

Hi Will,

Ok, we will revert to radvd 1.15 for the final 17.1 images.

I will mention this in the release notes that people running 17.1-RC will have to revert it manually because the package manager doesn't downgrade automatically.


Cheers,
Franco

I'm seeing this as well...

The downgrade fixed it.
