Packetloss between dedus01 and deleo01
![[de]](/s/countries/de.gif) Shadow Hawkins on Thursday, 26 January 2012 21:10:47
I have got a lot of packet loss between two diffent tunnels and the dedus01 and deleo01 POPs.
I think the problem is on the the leo-side. Can someone reproduce this problem?

ICMP is regularely rate-limitted thus not a good indicator of packet loss.
It would also be useful if you could include exact souce and destination adresses along with a tcdpdmp showing packetloss (for TCP one will see resends)

Hm, you should the adresses in my trace but here again...
source of pc: 2a01:198:4fb:0:6419:21be:6332:a223 (ip subnet from dedus01)
target: 2a01:1e8:e107::1000:1 (ip of subnet from deleo01)
Visiting the website via IPv6 from dedus01 is not realy possible. From other IPv6 routes like native IPv6 connection of Mesh or Hetzner datacenter no problems.
Here's also a dump from the target system during I ping the system from my local dedus01 tunnel.

Packetloss between dedus01 and deleo01
Shadow Hawkins on Friday, 27 January 2012 16:53:52
btw: I have no problems to ping my system (2a01:1e8:e107::1000:1) from mesh or hetzner with native connections and without any lost ICMP packets. I also have no problems to ping from my local dedus01 tunnel to my mesh or hetzner system without packetloss...
