What are you trying to do?
Ability for tailnet admins to configure global MTU for all devices connected to the tailnet.
decision was made at #246 to reduce MTU to 1280 for better support on every devices with different network conditions.
However, this come to an expense as QUIC/HTTP3 over tailscale might break #2633 and slow bandwidth might occur with overlays (cilium, etc) #12393
How should we solve this?
An option/textbox in the dashboard for tailnet admins to configure their MTU.
Validation checks on weird MTU numbers, or incompability (entering MTU values > 1420 out of 1500, etc..)
What is the impact of not solving this?
Manually configuring MTU on ifconfig, community members seems to be doing the same related to MTU issues.
Anything else?
