You cant disable it unless you're using a recoded version.

1) ICMP has nothing to do with unreal.
2) The only thing Unreal uses UDP for is resolving hostnames (and that's assuming it still does, since the latest versions are now using c-ares).

Those dont attack unreal, they attack the server unreal is running on.

Stopping those typically cant be done with software on the server itself. It would need to be done upstream, by your ISP or host.

The quick answer: you cant. An ICMP/UDP (DDoS type) attack is by nature unstopable.
