Bug #2526
closed
Limiter appears to break IPv6 connectivity
0%
Description
IPv6 connectivity through pfSense appears to be blocked when directed through a limiter (accessed under Firewall -> Traffic Shaper.) The applied traffic shapers work properly when IPv4 traffic is directed through them.
Attached is a screen cap of the limiter output when attempting to access IPv6 and IPv4 resources simultaneously.

This bug applies to 2.1 dev from June 28th as far back as June 20th. Prior to that dates build I was not using 2.1 and cannot comment.

On review of the screenshot it appears that the limiter is not assigning a bucket for IPv6 traffic denoted by "BKT 0". Additionally it appears that the limiter is not identifying the source/destination of IPv6 traffic properly as denoted by "::/0" for source and destination for each connection. IPv4 traffic has "0.0.0.0/0" for either source or destination and an IPv4 address for the other.

For informational purposes, this bug is still present. If a limiter is applied on an IPv6 rule, the traffic no longer passes.

Brought limiters up-to-speed with IPv6.

This problem appears to be present in the Wed Jun 12 06:19:03 EDT 2013 build. IPv6 Traffic hits the limiter as shown below but fails to pass. I did a clean install and created new limiters to be sure. The same limiter was applied to both default pass rules for IPv4 and IPv6. Using Chrome, the error message "Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data." is received when loading IPv6 enabled websites and IPv6 connectivity tests in multiple browsers fail.

A patch has been pushed which will fix limiters with ipv6.

Sorry, that did not help. Confirmed at https://forum.pfsense.org/index.php?topic=77506.0. No luck with this even with latest 2.2.2-DEV snapshots.

this is still an issue in some circumstances. To me to better quantify the circumstances where it's an issue.

Can you specify the scenario to check it?
Normally the only thing i see might be missing some parameter passing to dummynet to calculate the proper flow apart that i do not see any issue.

To be retested with a new snapshot there might have been issue with operator precedence in previous patch.

Well I think it looks good now.
Tested with bunch of speedtest stuff like http://ipv6-test.com/speedtest/, http://ipv6-speedtest.net/, http://www.thinkbroadband.com/ipv6/speed-test.html, some browsing, FTP, wget...
