clear DF bit on tunnel traffic

[deeiche]

On Mikrotik you can clear Do not Fragment flag with a mangle rule, https://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Mangle , clear-df - clear 'Do Not Fragment' Flag . OpenBSD also has support for this in it's implementation of EOIP.

Can you remove DF flag on traffic going through the EOIP tunnel?

If I am not misunderstanding, you can do the same on Linux with iptables in the mangle table

I have not been able to find iptable mangle table example to clear DF bit for specific traffic traversing EOIP tunnel.
