How to create a static NDP entry

[Evolve 0]

At System Monitoring — NDP Table | pfSense Documentation (netgate.com) it is explained that an entry in the NDP table (the IPv6 equivalent of Ipv4 ARP) can be permanent, in particular it is stated that if a NDP entry has a value of "Permanent" in the Expiration field than that means that “A static entry either located on the firewall itself (e.g. interface address, VIP) or a static NDP entry.

While I am able to create a static ARP entry I cannot find a way to create a static NDP entry.

Can anybody tell me how to do it?

Thanks a lot

@evolve-0 you would do it with the ndp command pretty much exactly how you can do it with the arp command.

https://www.freebsd.org/cgi/man.cgi?query=ndp&sektion=8

Or the same place you set in for v4 in the dhcp server settings area, but would be in the dhvpv6 area

@johnpoz Thanks a lot.

I really appreciate it.

About creating the NDP entry from the GUI I don’t see the equivalent NDP flag "Create an ARP Table Static Entry for this Mac & IP Address pair" that’s shown on the page of the IPv4 DHCP mapping, does this mean that creating a static IPv6 mapping automatically creates a static NDP entry for the MAC address associated with the DUID/IPv6 address static mapping?

Thanks again

@evolve-0 my bad - doesn't seem that the dhcpv6 reservation allows for that in the gui.

You would need to use the ndp command directly then..

@johnpoz Ok, that is great anyway.

Really thank you.
