Refer to post #346 by Moogle Stiltzkin

Not all ppl here are educated enough with ipv6, perhaps OP can have the purpose/benefit of it put on 1st page in a layman term. Tx.

facebook and youtube is extremely slow for me to the extent that it is unusable. Some other sites too. I've turned off IPV6 because of this.

how to set the correct MTU value for ipv6?

should i follow the same set for ipv4?

The reason why Facebook/Youtube can be slow when IPv6 is enabled is because the MTU is too high. I use the MTU of 1280 in ND setting so that those websites will be easily accessible, plus solve the problem where some Android devices. 1452 is definitely not low enough for all devices.

What's ND Setting?

Neighbour Discovery.

I couldn't find this setting in my TomatoUSB.

Where is the setting in TomatoUSB?

The only MTU setting I can find which is in
the WAN settings and the default value is 1492.

Is this the one?

I'm not familiar with TomatoUSB, but you can try changing that value.

What router are you using?

I use routerOS. MTU is set at ND setting, because its dialer does not support IPv6.

i'm still trying to understand ipv6 through packetlife site http://packetlife.net/blog/2010/apr/12/ipv6-pros-and-cons/

btw they made a cheatsheet out of it, thought i might share it here

may i ask how you find the proper value for ipv6 MTU?

i know for ipv4 we can ping its fragment to get desired results e.g
ping -f -l 1472 google.com

until you get the results without 'Packet needs to be fragmented but DF set.'


how about ipv6 maybe you can share?

No, I just arbitrarily choose that value after researching why Jelly Bean Android phones has big red connectivity problems at http://test-ipv6.com/ test page.

My IPv4 best MTU is 1464 + 28 = 1492 like the default one.
