IPV6 troubles

Sun Feb 26, 2017 7:02 am

/ipv6 address
add address=2a01:d0:ffff:5a59::2 interface=6to4-tunnel1
add address=2a01:d0:da59::1:1 interface=bonding1
add address=2a01:d0:ffff:5a5f::2 interface=6to4-tunnel2
add address=2a01:d0:da5f::1:1 interface=bonding1
add address=2a01:d0:ffff:5a60::2 interface=6to4-tunnel3
add address=2a01:d0:da60::1:1 interface=bonding1
add address=2a01:d0:ffff:5a61::2 interface=6to4-tunnel4
add address=2a01:d0:da61::1:1 interface=bonding1
/ipv6 nd
set [ find default=yes ] advertise-dns=yes interface=bonding1 \
    managed-address-configuration=yes mtu=1480 other-configuration=yes \
    ra-lifetime=10m
/ipv6 route
add !bgp-as-path !bgp-atomic-aggregate !bgp-communities !bgp-local-pref \
    !bgp-med !bgp-origin !bgp-prepend check-gateway=ping distance=1 \
    dst-address=2000::/3 gateway=\
    6to4-tunnel3,6to4-tunnel4,6to4-tunnel1,6to4-tunnel2 !route-tag
/ipv6 settings
set max-neighbor-entries=1024
IPV6 does work on router, i can ping or trace from router to anywhere.
But sadly IPV6 does not pass the router.
I can ping router's IPV6 addresses but can't reach past it.
When i trace from LAN i see first hop is my router and then just nothing.
This config did work for a day and then stopped working for LAN.
Any ideas how to fix it?

Check what exactly happens. Do your LAN clients get addresses from your external DHCPv6 server? Did you check on router (either using Tools->Torch or by loggin rules) if traffic comes to router and passes correctly (i.e. you don't block it using firewall)? Etc...

No, static address used.
On test machine addresses are 2a01:d0:da59::1:2/64 and so on (same as on bondding1 but at end 2 instead of 1)

Traffic comes to router (reaches bonding1) but does not reach any of 6to4 if cones from LAN.
But if traffic goes from router(ping or trace from router) it goes normally reaching 6to4 and outside, also from router i can reach ipv6 inside my LAN.
So problem is somewhere in the outer.

Firewall?

Also check if ipv6 -> settings -> forward is set to "yes"
