routing ipv6 only in local wlan network (subnet)
1
I have a Gentoo Linux machine with got a V6 address via DHCP form my router. There is V4/V6 net. For DHCP I use dhcpcd with following conf:
duid
persistent
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option interface_mtu
require dhcp_server_identifier
slaac private
noipv6rs
interface eth0
ipv6rs
ia_na
interface wlan0
noipv6rs
noipv4
ipv6only
I try to create a router for internal wireless v6-only network.
I try to do the following:
Assign static address for wlan0 from v6 network:
# ip addr show wlan0
5: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1480 qdisc mq state UP group default qlen 1000
link/ether 50:3e:aa:54:c2:c5 brd ff:ff:ff:ff:ff:ff
inet6 2001:470:xxxx:1000::1/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::b614:22ce:a510:66e3/64 scope link
valid_lft forever preferred_lft forever
Add dnsmasq witch config:
interface=wlan0
listen-address=2001:470:xxxx:1000::1
no-resolv
server=2001:470:xxxx::1
local=/subnet1/
domain=subnet1
dhcp-fqdn
enable-ra
dhcp-range=::100,::1ff, constructor:wlan0, ra-names, 64, 12h
log-queries
log-dhcp
Clients have got V6 addresses but no internet access. I can ping wlan0 clients from Gentoo machine but I can't ping global addresses from wlan0 and clients.
# ping6 google.com -I wlan0
connect: Network is unreachable
Should I add some static route for wlan0?
Current route table:
2001:470:yyyy:zzzz::/64 dev eth0 proto ra metric 204 mtu 1480 pref medium
anycast 2001:470:xxxx:: dev eth0 proto kernel metric 0 pref medium
