Title: IP alias & virtual masks limited to IPv4-only? Want to add v6 ULA address.
Post by: unquietwiki on June 22, 2022, 09:45:36 am

Hey everyone. So I support a site that has nascent IPv6 support from its ISP via DHCPv6. Internally, we use a ULA to support internal traffic over our VPN, virtual machines, & local site systems. However, there is not presently an obvious way for me to have both a "tracked" IPv6 LAN address, as well as a static address for the ULA. Some other folks have suggested virtual IP, or IP alias; but as of 22.1, the only netmasks for those addresses are 32 or less, which means IPv4-only.  ??? Please advise. Thank you.

The mask will change automatically to v6 ranges after entering an v6 address. At least when saving it changes to /128

Thanks for the quick reply; I'll try it later. Seems counter-intuitive, from a UI perspective.

The UI idea seems to be that people type in or paste the address first. The mask options change accordingly. I think that's pretty neat.
