ping and traceroute works, but other traffic times out
![[dk]](/s/countries/dk.gif) Shadow Hawkins on Tuesday, 28 December 2010 19:43:23
I've set up my tunnel and subnet on my Apple Time Capsule and I've configured IPv6 on my laptop but I'm unable to use IPv6. It seems that ICMP6 is working as it should, but all other traffic is failing.
I'm able to ping and traceroute IPv6 hosts, but I can't telnet or see websites in my browsers:

I forgot this in the original ticket:
Snowwhite:~ maaboe$ telnet ipv6.google.com 80
Trying 2a00:1450:8004::69...
telnet: connect to address 2a00:1450:8004::69: Operation timed out
telnet: Unable to connect to remote host
Everything else than ICMP6 times out.

ping and traceroute works, but other traffic times out

I did. But here goes again:
* Always include clear descriptive information about your problem or inquiry.
I've configured my tunnel (T48973) on my Apple Time Capsule (ATC), I've setup my subnet and the ATC autoconfigures hosts on my local network with IPv6 addresses. When I ping or traceroute ipv6.google.com it works, but I can't access ipv6.google.com or any other site using a browser or using telnet to port 80. The connection times out. The same happens if I try to access other IPv6 enabled hosts with anything other than ping and traceroute.
I've tried configuring a Hurricane Electric (HE) tunnel in the same way, and I had full IPv6 connectivity. So, somehow it seems there's a difference between HE and SixXS that gives me problems.
* Always provide your NIC handle and if applicable the Tunnel or Route IDs you wish to discuss.
NIC Handle: MJU7-SIXXS
Tunnel ID: T48973
Subnet: R21701
* Provide details of the setup, type of connections, where NATs are located.
Apple Time Capsule acting as wireless router connected to Zyxel DSL-modem in bridging mode. ATC is configured with static public IPv4 90.185.22.12 on the WAN and the SixXS-tunnel to the dkcph02 POP:
IPv6 WAN: 2a02:980:1000:12::2
IPv6 default route: 2a02:980:1000:12::1
IPv6 LAN: 2a02:980:1009::6233:4bff:fe2e:326b
ATC is doing IPv4 NAT. Computer is connected to wireless network and receives DHCP IPv4 and autoconfigured IPv6.
* Provide information of your OS type, version and release (ie. uname -a), noting also the distribution name.
Apple Time Capsule, running firmware 7.5.2
Macbook laptop, running Mac OS X 10.6.5, Darwin Snowwhite.local 10.5.0 Darwin Kernel Version 10.5.0: Fri Nov 5 23:20:39 PDT 2010; root:xnu-1504.9.17~1/RELEASE_I386 i386
* Include full interface, routing and firewall tables.

Routing table
Firewalling is disabled on the Time Capsule. ipfw rules on computer:

* Include a IPv4 and IPv6 traceroute to the PoP in question.
Traceroute
+ tcpdump
tcpdump
ping and traceroute works, but other traffic times out
I can only assume that 'snowwhite' is your client, thus what are the routing tables on your gateway node? And especially the tunnel configuration?
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1280
Why do you have an Ethernet with an MTU of 1280 bytes? That normally is 1500 bytes. The tunnel is most very likely 1280
+ tcpdump tcpdump
What is this tcpdump supposed to illustrate? I don't see any TCP interaction (which is the thing that is breaking according to you). Also, if possible please provide the raw pcap (-w) as that provides a lot more details than -X.
At the moment 2a02:980:1000:12::2 does not even answer ping requests and I think that your host is not even up from what I can tell.

Ok i have done some more testing and debugged with our upstream provider (TDC) and it turned out it was a to agressive peering filter.
Service should be operating again.
