Hi guys,
I need help with the MTU configuration.
My ISP has an MTU of 1280 in IPv6.
[root@Corona.localbar]/root: ping6 -D -s 1232 heise.de
PING6(1280=40+8+1232 bytes) 2a00:XXXX:XXXX:XXXX:: --> 2a02:2e0:3fe:1001:302::

^C

5 packets transmitted, 0 packets received, 100.0% packet loss
How can I adjust this in the config?
I have so far.
tun-mtu 1500
fragment 1280
mssfix 1280
Is that correct?
