21.7 Legacy Series / IPv6 working great, RADVD log still saying Network is down
« on: September 29, 2021, 03:13:49 pm »
I finally got around to implementing IPv6 on my network. It works great on all subnets and I score good on the connectiontest on internet.nl and test-ipv6.com. It works on Debian, Android, iOS, MacOS and Windows. However the RADVD log registers an error around every five minutes:
2021-09-29T15:03:30 radvd[80798] sendmsg: Network is down
2021-09-29T14:56:25 radvd[80798] sendmsg: Network is down
2021-09-29T14:51:31 radvd[80798] sendmsg: Network is down
2021-09-29T14:47:39 radvd[80798] sendmsg: Network is down
2021-09-29T14:39:50 radvd[80798] sendmsg: Network is down
I'm currently running:
OPNsense 21.7.3_1-amd64
FreeBSD 12.1-RELEASE-p20-HBSD
LibreSSL 3.3.4
My ISP provides me with a /48 via DHCPv6 through the IPv4 PPPoE tunnel. On my WAN interface I selected DHCPv6 as IPv6 Configuration Type and checked the following options
Request only an IPv6 prefix *checked*
Prefix Delegation size 48
Send IPv6 prefix hint *unchecked*
Use IPv4 Connectivity *checked*
Use VLAN priority *Disabled*
On the LAN interface (and others) I selected Track Interface as IPv6 Configuration Type and selected the following options:
IPv6 interface: WAN
IPv6 Prefix ID: (whatever the VLAN of that particular interface is to make it more recognizable)
Manual configuration *unchecked*
Anyone has any idea what could be wrong? Everything seems to be in working order, so troubleshooting is a bit tough. Any help would be appreciated. Thanks!
