Hi,
Anyone know how to change IAID on WAN interface ?
Looks like Opensense use IAID=0 on WAN by default.
Mikrotik gives
lo interface IAID=1
First Interface IAID=2
Second Interface IAID=3
You can set that under Interfaces: WAN -> "DHCPv6 client configuration" -> "Advanced" tab -> "Prefix Delegation" -> "id-assoc pd ID"

Thanks.
When I switch to Advanced,
I can't find where to set:
Prefix delegation size and
Send prefix hint
See this. You can also inspect the normal "Basic" version of /var/etc/dhcp6c_xxx.conf and directly produce the contents of the file on the Config File Override tab.
Thanks:-)
I am still having problems with getting IPv6 address from my ISP Altibox.
Could there be some trotling of Solicit messages ?
