slow speeds for any IPv6 tunnel traffic
![[ph]](/s/countries/ph.gif) Shadow Hawkins on Tuesday, 05 June 2012 16:25:16
Hi,
I have just setup my tunnel to uschi03 and I have full connectivity to IPv6 but the speed is really slow.
I am based in the philippines, and I have a dynamic heartbeat tunnel setup with an MTU of 1280 based on a wiki page I saw.
The tunnel is terminated on an Cisco 877w router with 12.24T7 Advipservices IOS
My tunnel settings are:
interface Tunnel1
description IPv6 uplink to SixXS
no ip address
ipv6 address 2604:8800:100:176::2/64
ipv6 enable
ipv6 mtu 1280
ipv6 nd prefix 2604:8800:100:176::/64 no-advertise
ipv6 rip ipv6rip enable
ipv6 virtual-reassembly
tunnel source BVI1
tunnel destination 38.229.76.3
tunnel mode ipv6ip
My speed test at speedtest reveals my IPv6 address of 2604:8800:100:8176::2 which is correct, but the speeds after completing the test are:
IPv4 2.5 Mbps [local]
IPv6 5 Kbps [tunnel]
Other Details:
OS: Ubuntu 12.04 Kernel 3.4
AICCU Ver : 2007.01.15
NIC : eth0
Tunnel Information for T95806:
POP Id : uschi03
IPv6 Local : 2604:8800:100:176::2/64
IPv6 Remote : 2604:8800:100:176::1/64
Tunnel Type : 6in4-heartbeat
Adminstate : enabled
Userstate : enabled
AICCU Test : pastebin
Firewall : None (testing connectivity at this point)
Please let me know if you require anything else

Can someone please close the last [ code ] for me if that's possible?

please close this
I implemented basic IPv6 inspection and firewall on the cisco and this was causing problems because I had the in/out statements reversed on the tunnel interface
I have done the same tests and now get full throughput on my 2.5Mbps dsl line over the tunnel
Cheers :)
