[Solved] No DHCP6 gateway

[pp]

Not sure when this started but my WAN_DHCP6 gateway appears to not get configured correctly:

My WAN is configured with DHCPv6 and I set a Prefix delegation size of 59 in its options.
Interface Overview shows an address (/128), a link-local address (/64), a delegated prefix (/59) and 2 IPv6 DNS servers but no IPv6 gateway.

The "IP address" field in the default created WAN_DHCP6 gateway is set to "dynamic" but the gateway field stays empty.

The log file shows the following:

Code Select Expand


/system_gateways.php: ROUTING: not a valid default gateway address: ''
/system_gateways.php: ROUTING: configuring inet6 default gateway on wan


Not sure if this is an issue with my ISP (Vodafone Cable Germany) who did some non-standard IPv6 in the past.

For now I check my WAN's neighbors via NDP and use the listed CMTS IP (fe80:...) as a manually added IPv6 gateway which works but I am wondering why it is not detected/used by DHCP6.

Any suggestions how to better debug this? Thank you.

Your ISP may not be sending a RA which pinpoints the server. Let's check the system...

# ls /tmp/*_routerv6

That command shows "ls: No match.".
I have a igc0_router file containing the IP4 gateway only.

"Have you tried turning it off and on again?"
Just got it solved by restarting my modem. Sorry for the noise.

All the better :)
