Limiter and IPv6
-
Does anyone have limiter working with IPv6? Ive been playing around with it and it doesn't seem to work 100%. I'm able to browse to some pages but they don't completely load. While other don't load at all, example is Facebook. I'm running 2.1.3 i386 at the moment.
While searching, it does seem to be a known issue… Is it on pfSense radar to fix in 2.2 perhaps? If not, I'll go ahead and open a bug report based on the last comment in the below link

Hi,
Anyone else with this issue. Bumping it so that devs may notice.
-
bump

Bump, same behaviour on 2.2
-
I have tried it myself in 2.2 yet…
Can you provide details to open a bug report?
-
well I
ve just set limiter 10 Mbit DL and 10Mbit UL and on IPv4 it works on IPv6 it doesnt.
Pages are loading or not, pings are timing out, unstable behavior… -
Does this actually work for anyone? Sure like hell not here on 2.2.1 - despite the bug suggesting otherwise.
-
Nope, it does not work.
-
OK, thanks for confirmation. Going to nag on the bug.
-
Works for me on 2.2.1, what specifically are you trying that doesn't work?

Well, what's described on the bug and here. Extremely simple - it totally kills IPv6 traffic. I have a simple 8 Mbps Down/ 2 Mbps Up limiters. Assigned to an alias of bandwidth limited hosts on LAN and as a floating rule on WAN. IPv6 sites like www.google.com are totally inaccessible from the aliased hosts once the limiter rules are enabled. The now disabled IPv6 rules - screenshots below - simply kill traffic. I can browse IPv6 site just fine as soon as I stop limiting TCP. If I apply the limiter to all protocols, I cannot even ping IPv6 from those limited hosts to hosts on Internet. The limiters work perfectly fine with IPv4. There is no difference between the rules except for IPv4 vs. IPv6.
Limiters:
LAN:
WAN/HEIPv6 tunnel (floating, direction In):

Same goes for me…

Same here. I used a limiter to limit inbound ICMPv6 traffic. This resulted in echo replies not being send out altogether. The matter is rather strange and might be hard to debug as seems to work from one location and not from another. Like, the queue filling up and dropping any additional traffic from the source.
I just confirmed it with my tunnel broker, SixxSx. After switching on the limiter, packets are dropped. But, not right away but after some time.
-
Edit: scratch that, found a way to replicate.
-
Hmmm ok I used 32 bit.
I just migrated to 64 bit yesterday, will try it out asap. -
Nope.
Tried with 64bit and same results… test-ipv6 didn`t finish, pages are super slow limiter set to 7/7 Mbit/s. -
I am running 32bit as well on the system tested.
-
Nope.
Tried with 64bit and same results… test-ipv6 didn`t finish, pages are super slow limiter set to 7/7 Mbit/s.what type of v6 connectivity do you have?

Just wanted to note that I'm seeing the same issue with limiters and IPv6. Running 2.2.1-RELEASE (amd64). I have native IPv6 via DHCP-PD, requesting a /60 from my ISP.
I created a second network… static IPv4 and Track Interface IPv6 (prefix 1). I created an out limiter of 5Mbit/sec and an in limiter of 1Mbit/sec. When I apply the limiters to the Allow rule on that second network interface, IPv6 no longer functions. A test page will load via IPv4, but all IPv6 tests will fail. When I remove the limiters, IPv6 works great. IPv4 works fine whether the limiter is in place or not.

I can replicate issues now, put the bug back to confirmed and to me. https://redmine.pfsense.org/issues/2526
