timestamp and timestamp-reply blocking

[UsagiXUsagi]

Greetings,

Can we block ICMP timestamp and timestamp-reply on dashboard?

I think if there is a setting to do that, it should be in the page of Security Appliance>Firewall.

But I couldn't find it.

Negative.

Did you know using timestamps is a really useful method for resolving throughput and tcp re-transmission issues on asymmetric crciuits, like ADSL?

It fixes far more problems than it causes - so I really wish people didn't do this.  The threat posed by timestamps and the implementation in OS tcp stacks was resolved long ago.
