    IPFW ipfw filter for tcp IPv6 on Freebsd 11

    Hi I am using ipfw for firewalling on a FreeBSD 11 box. Unfortunately I cannot wrap my head around the fact that/why the following rule does not match when I initiate a TCP connection to 2a00:1450:4001:814::2003 (that is Google...): ipfw add 340 set 5 count dst-ip6 2a00:1450:4001:814::2003...

    How can I assign an IPv6 address to a jail on a cloned interface?

    Hello, I have some jails on my FreeBSD host. They have IPv4 addresses on a cloned interface lo2 I created. None of the jails has an ip address on the external interface of the host. They only use the cloned interface lo2 and I configured my pf firewall so that the host acts as a router and does...

    Jail IPv6 only works after base initiates connection

    Hi all, When I start the jail, I get this message on my console. nd6_dad_timer: cancel DAD on epair1b because of ND6_IFF_IFDISABLED. Then the jail cannot use IPv6 until the base initiates connection to it (ie, the base pings the jail first). Otherwise, networking over IPv6 does not work Any...

    Configuring an IPv6 gateway - a few questions

    Hi forum. Until recently I ran pfSense on my gateway system for my home vDSL connection, but I decided to revert to plain FreeBSD and relearn how to configure everything manually. I've got it up and running with the typical setup of a private subnet (two in my case) NATed behind a single...

    Jail does not respond over IPv6 until it initiates traffic

    I am experiencing this odd issue when I restart one of my jails, which operates as the IPv6 router, does not respond to IPv6 packets, even though tcpdump reveals that it receives them. It isn't until it initiates a traffic with other hosts that it starts to respond. IPv4 works just fine. I have...

    Robust sh script to obtain all IPv6 address on an interface?

    While ipfw supplies me6, I need the list of IPv6 addresses for a specific interface to be used in an ipfw ruleset. "Screen scraping" ifconfig is one option, but having a firewall at the whim of the human-readable output of even ifconfig is concerning. Is there a better way with the "stock"...
