This is a multi-part message in MIME format. --------------qex0KsiaZ8uqiPgewYcgtLE3 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Hello, I am trying to get my laptop to receive an IPv6 address using SLAAC on my local network. I suspect that the router provided by my ISP is doing something slightly wrong or I may just have configured it wrong. I am running FreeBSD 14.0-RELEASE-p3. The network interface looks like this when queried with ifconfig. wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=0 ether 18:1d:ea:b1:f9:8b inet 192.168.0.129 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::1a1d:eaff:feb1:f98b%wlan0 prefixlen 64 scopeid 0x2 groups: wlan ssid ARRIS-8030 channel 6 (2437 MHz 11g) bssid e4:f7:5b:25:ff:da regdomain FCC country US authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 10 scanvalid 60 protmode CTS wme roaming MANUAL parent interface: iwm0 media: IEEE 802.11 Wireless Ethernet OFDM/54Mbps mode 11g status: associated nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> I have attached my rc.conf and pf.conf files to this mail. I have also attached a tcpdump showing router solicitations going out and router advertisements being received. My pf.conf should be open enough for this to work but for completeness I have also tried with pf disabled with the same result. When running Ubuntu on the same laptop or even in a Virtualbox VM with bridged networking, Ubuntu manages to configure IPv6 without problems. Likewise with a Windows VM. I appreciate if anyone here can spot what goes wrong and suggest if I need to configure something differently or whether a code fix will be needed to support this network. I can try patches if necessary. Thanks.
