Hi *,

> 0 = disabled
> 1 = enabled

that is clear. But I don't understand which is the consequence when I
change the option! What means the options exactly? What for a behavior
changes this?

Best regards,
Frank

Good morning,
I think it's
/usr/sbin/no -o tcp_pmtu_discover=0
/usr/sbin/no -o udp_pmtu_discover=0

I would venture to say that you can savely give it a try (and then have a
look with iptrace / ipreport for icmp packets)

HTH, Christian
