Dual WAN Setup - LAN interfaces lost their IPv6 adresses.
-
Yes I use a DHCP Relay. DHCP Server runs on Windows Server 2025.
-
Same interface ?
Or another interface that went (also) down ? -
@Gertjan Yes, it is on the same Interface, but only v4.
For IPv6 I deactivated DHCPv6 (on the Pfsense) and at the moment I run only Slaac / Router Advertisement. -
Hmm, so you are passing a prefix delegation from your ISP to an internal dhcpv6 server?
Please show how your pppoe interface is configured. Is it set to prefix only? Is it set for 'do not wait for RA'?
-
No, the DHCP Relay is only for my internal LAN-Interface, and only IPv4, I think this was an missunderstanding.
and one of the LAN Interfaces (called EXT)
-
If you uncheck 'do not wait for RA' does it eventually receive an RA and complete the connection?
Edit: So when this happens it loses the PD but not the address on the WAN directly?
-
@stephenw10 I will give it a try, and give a feedback after.
