Hi Alan, I'd like to make the abfab-tls configuration file (https://github.com/FreeRADIUS/freeradius-server/blob/v3.0.x/raddb/sites-avai...) to accept both, IPv4 *and* IPv6. For what I've read, I cannot have two ipaddr (in any of its variants) taking place within the same "listen" section but instead I have to duplicate the "listen" section. Is that right, or is there any other more convenient way of doing it that I'm missing? For the "clients" section, I guess that adding something like: client default_ip6 { ipaddr = ::0 proto = tls } would suffice, right?
