ipv6 tunnel anq Google services

[natriy81]

Hi,
I have a problem to get Google services (gmail, youtube, i.e.)  over ipv6 tunnel:

Code Select Expand


ping ipv6  ipv6.google.com  size 1000 source Tun1         

Type escape sequence to abort.
Sending 5, 1000-byte ICMP Echos to 2A00:1450:4010:C08::65, timeout is 2 seconds:
Packet sent with a source address of <omitted>
CCCCC
Success rate is 0 percent (0/5)

...

ping ipv6  ipv6.google.com  source Tun1         

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2A00:1450:4010:C04::65, timeout is 2 seconds:
Packet sent with a source address of <omitted>
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 84/84/84 ms


But other  hosts are  available:

ping ipv6 www.ipv6tf.org  size 1000 source Tun1 

Type escape sequence to abort.

Configuration of ipv6 tunnel:

Code Select Expand


sh run int tun1
Building configuration...

Current configuration : 352 bytes
!
interface Tunnel1
description -= Hurricane Electric IPv6 Tunnel Broker =-
no ip address
ipv6 address <omitted>
ipv6 enable
ipv6 traffic-filter ToTunnelBroker in
ipv6 mtu 1280
ipv6 inspect tunnel-broker out
ipv6 virtual-reassembly
keepalive 10 3
tunnel source Loopback1
tunnel destination <omitted>
tunnel mode ipv6ip
end


How can I fix ?

I'm confused...what exactly are you trying to accomplish?

Sites  gmail.com, yoube.com, google.com  open  too slow, because  packets size  bigger than  64 bytes are dropped:

this is only an issue with he.net's tunnel.  You can sign up for a gogonet tunnel and it works fine.

You're likely hitting a different cluster of Google's which isn't exhibiting this on a gogo tunnel.  SixXS was also seeing this in spots.  As it is, it should be resolved according to Google.

Thanks you. I changed  ipv6 forwarders   in my named.conf.  After that the  problem was fixed:
