SLAAC & Dynamic prefix
-
Hi,
My ISP gives me a dynamic prefix and it is well managed by the DHCPv6 server (the prefix is correctly detected).I also use SLAAC (RA assisted mode) to provide IPs for other devices.My question is:
When my prefix change, I always have to enter it manually (copy/paste from DHCPv6 server) in the RA Subnet(s) to get routable IPs. Is there a workaround to avoid this and to do it automatically ?At the beginning, I wanted to use only SLAAC but due to the dynamic prefix, I have been forced to use the DHCPv6 server.
Thank you.

You can use Unique Local Addresses for your local network. However, first check to see if System / Advanced / Networking / Do not allow PD/Address release has been selected. If it isn't, your prefix will change.

It's working fine with ULA but I had to setup NPTv6 with the delegated prefix of my interface (automatically detected and preset).
I also disabled the DHCPv6 and set the RA in unmanaged mode to have the initial setup I wanted.
I reset my WAN manually for checking and everything is working perfectly.
Thank you. -

@YannTKO are you asking about
RA Subnet(s)
Subnets are specified in CIDR format. Select the CIDR mask that pertains to each entry. If no subnets are specified here, the RA Daemon will advertise to the subnet to which the router's interface is assignedIf so note the bolded part and leave it blank.
