Germany T-Online

Has someone else trouble with the T-Online MTU numbers?

Default should be 1492, but lately I have to throttle them down to 1440 or even 1400.

I chose 1460 as MTU, because there were several connection problems with 1492.

Hi,
I had the problem! I do not know which MTU is the best?
Currently I am running with 1492. But maybe lower values
result in better speed?

What do you mean by >several connection problems

FYI:
T-DSL Business customers are told to use MTU of 1456 in their router configuration.

Yes, thats one of 5 numbers I got from t-online. Trouble is, they change on the fly, for the regular customers. And normaly a router would adapt the new MTU, but Astaro is a little "stuburn" on this matter. [;)]

hi,
i am new to astaro, but before i have used a Debian box as firewall/router, and there i got 1492 setup, and i never got problems. i am a 24h onliner and got till now only connection problems, when a thunder hits the powerlines and i got now power.

Also till now i have no problems while using the internet with 1492, but i got another problem, that my astaro gets offline after 2 days online. Perhaps astaro got there a little problem, but i dont know right now.
