I need your help to configure native IPv6 router on FreeBSD.

  1. Interfaces configured well, on both I can see two addresses (real and link local).
  2. I can ping ipv6.google.com and when do lynx www.kame.net, I can see phrase: dancing kame.
  3. I installed radvd and get IPv6 address from server.
  4. I'm using SSH connecting from my local computer to server using IPv6 address.
  5. I can ping from local net both my router interfaces.
  6. Using tcpdump on both interfaces, I can see that echo requests from my local computer are going to ipv6.google.com, but without response.

So, I think that my server doesn't work as router. As prove of my words, when I do ping on my external interface:

 ping6 -I em0 FF02::2

(Pinging link local addresses of neighbor routers.) I can't see my router link local address in this list. So, my router doesn't advertise herself as router and nobody know about my subnet.

Here is rc.conf cut:

ipv6_activate_all_interfaces="YES"
ip6addrctl_enable="YES"
ip6addrctl_policy="ipv6_prefer"
ifconfig_em0_ipv6="inet6 2a03:XXXX:XXXX:XXYY::1 prefixlen 64"
ifconfig_re0_ipv6="inet6 2a03:XXXX:XXXX:XXXX::fffe prefixlen 64"
ipv6_defaultrouter="2a03:XXXX:XXXX:XXYY::fffe"
ipv6_gateway_enable="YES"

Here is sysctl flags:

net.inet6.ip6.forwarding: 1
net.inet6.ip6.redirect: 1
net.inet6.ip6.hlim: 64
net.inet6.ip6.maxfragpackets: 16384

Please tell me, what have I missed?

This is FreeBSD? How did you get an interface named "eth2"? You seem to have "em0" and "re0" but no "eth2". –  Michael Hampton Feb 8 at 1:34
    
You're right, sorry. I just copied it from my notes. And they was written for Linux. –  user2443795 Feb 8 at 7:25

Have a look at handbook ch30.11 I think rtsold and rtadvd are needed for ipv6 routing. –  sambler Feb 8 at 10:07
