Hi
I have following setup at home ,I am sharing internet
with neighbour , our ISP provides IPV6
With 2001:16a2:cdd2:xx00::/56 prefix delegation , until now I was only using
IPv4 NAT with following setup
ISP-Router————OPENBSD/PF————VLAN10—openWRT—------------Macbook
|
____VLAN20__openWRT____ ____ some Devices
|
|
Neighbour Access Point
Recently I tried to enable IPv6 in openbsd
i can ping6 google.com from openbsd firewall itself
but i cannot route ipv6 traffic from LAN side devices
i can get ipv6 address assigned to my LAN devices
ps:isp provides only dynamic ip's not static
/etc/hostname.iwn0
inet6 autoconf -soii -temporary
inet 192.168.100.177 255.255.255.0
Ifconfig iwn0
inet 192.168.100.177 netmask 0xffffff00 broadcast 192.168.100.255
inet6 2001:16a2:cdd2:xx00:xxx:faff:fe92:c7c6 prefixlen 64 autoconf pltime 86081
vltime 86081
This is connecting to ISP Router with ipv4 LAN side ip
And NAT with pf firewall
vlan10
