    IPv6: Preventing EUI-64 link-local addresses being used over manually configured ones on router

    Hi. I run an IPv6-enabled FreeBSD router on my home network, which has been working fine for years. I have a global-scope /48 prefix delegated by my ISP, from which FreeBSD advertises a /64 chunk to my LAN. IPv6-enabled hosts on the LAN see the router advertisements and configure themselves...

    Solved Static IPv6 for local network

    Hi, I have a box acting as a gateway for my lan at home. It connects through PPPoE (tun0) to the provider and gets the configuration for the outside world (I'm using net/dhcpcd). The clients (on the lan) are served by rtadvd and net/dhcpd. I have a 192.168.1.0/24 network for LAN and also want...

    I'm running an AP that bridges traffic to my ISP. For various reasons, I'm running both IPv4 and IPv6 and I need to NAT traffic from the LAN to the ISP.

    FreeBSD is not answering neighbour solicitation

    Hi This problem originated from my pfSense installation, but I just confirmed that I'm having the same problem with a clean installation of FreeBSD 12.2, so I thought I would ask here. The problem is that FreeBSD does not answer NS send from my ISP's router, which results in no communication...

    Sendmail access.db and IPv6 prefixes

    Hi all, I need to specify an IPv6 prefix in /etc/mail/access using CIDR notation and it doesn't seem to work (nor can I find it documented). My range is similar to: "2001:DB8:1111:2200::/56". My network doesn't fall on a 16 bit boundary so I can't just specify "2001:DB8:1111:22" as this is...
