[RoS 5.22] Unable to set 6to4 tunnel via anycast

Hello,

I've been trying to set up 6to4 tunnelling on my RB450G and I've run into problems.

Here's my setup:

/ip address
add address=10.15.39.39/28 disabled=no interface=ether1-gateway network=10.15.39.32

/interface 6to4
add disabled=no local-address=178.135.15.49 mtu=1280 name=sit0 remote-address=192.88.99.1

/ipv6 address
add address=2002:b287:f31::1/3 advertise=no disabled=no eui-64=no interface=sit0
add address=2002:b287:f31:1::1/64 advertise=no disabled=no eui-64=no interface=ether1-gateway
add address=2002:b287:f31:2::1/64 advertise=yes disabled=no eui-64=no interface=ether2-master-local

/ipv6 route
add disabled=no distance=1 dst-address=2000::/3 gateway=::192.88.99.1%sit0 scope=30 target-scope=10

I should mention that although I have local address on my ether1-gateway (10.15.39.39), it has a public IP (178.135.15.49) which is 1:1 mapped on my local one.

With this setup, I am unable to reach any IPv6 address:

/ping 2a00:1450:400d:803::1010
HOST                                     SIZE TTL TIME  STATUS                   
2002:b2f8:f95f::1                         104  64 1ms   address unreachable

I've tried several guides and it looks like I have the exact setup for 6to4 tunnel. I tried updating RoS to 5.22, restarting RB and re-creating all the settings.

Anyone has any idea?

Thanks,
