1500

Then do a test from a wired PC:

LINUX:
ping -c4 -M do -s 1472 1.1.1.1

WINDOWS:
ping -f -l 1472 1.1.1.1

The pings should be successful..

ugh!

after all that, my Asus router wont let me change the MTU to anything over 1492 using the GUI

What now ? is there a telnet command i can use to force it and each time the router is rebooted ?

thanks

It may simply not support MTU 1500+8=1508, if so you either get a better router or stick with the MTU 1492.

I canít talk because I moved heaven and earth to ensure I got MTU 1508, but in practice itís not important for most situations and I suspect even less important if youíre using IPv6 (which we are all moving towards more and more often; I use IPv6 all the time).

Maybe give pfsense a whirl on an old PC.... you can use your current router just as an AP
... or ebay it  :)

Good plan.

Guys - can pfsense be run in a Raspberry Pi?

I need to use Merlin firmware on my Asus RT-AC68U to get 1500 MTU working.

The stock Asus firmware wouldn't allow it.

opnsense can though, it's a fork of pfsense after the developers disagreed https://forum.opnsense.org/index.php?topic=12186.0

You will see absolutely no difference setting MTU to 1500.  In many cases servers we connect to are set to use 1492 (or less) anyway due to the sheer amount of PPPoE Internet connections in use around the world.

pfSense though does work and for me was easy, it took 5 seconds, the time it took to type 1508 and press Save.  However that still needs support of the network interface pfSense is using and the port on the modem you are using.

Honestly though, it isn't worth the time and expense of new equipment just to get 1500, it's fools gold :-)

I'm fairly sure all servers will be set to 1500 as people simply wont bother to change the default when MTU discovery will do its job just fine.  They are also going to want traffic within the data centre to be as efficient as possible.

The only services I'm aware of that default lower are games console services which want to make absolutely sure nobody has to fragment packets as it would be detrimental to the latency.

Hi

Don't worry about it, its mostly a placebo effect for those of us making the change where our hardware allows ;D  There is absolutely no need to change anything and 1492 is an optimal setting used by millions in the UK and many more across the world. If you want more of an explanation see my post here https://forum.kitz.co.uk/index.php/topic,24232.msg408064.html#msg408064

https://github.com/johnson442/custom-zyxel-firmware

Finally got the docker build cleaned up and put on github.

A reasonable amount of combinations built and tested for 1312 & 8x24 based on latest V17 & V28 source are available under the releases section:

https://github.com/johnson442/custom-zyxel-firmware/releases
I have just a few questions about the modem stats server:

1) Does it mean you don't need a monitoring software such as DSLstats ?

2) Are the stats always ON - as long as the modem is up and running - and saved into the internal memory ?

3) If yes, what will happen when the memory is full ?

4) Do you have a version with jumbo+stats+tel ?

Tia.
