Is there any console command or tips to simulate a network latency between clients and server?

If you happen to be on Mac then you can use XCode Network Link Conditioner which is about the best tool I’ve come across for this kind of thing.

Linux you can use ‘ipfw’. This is a little more tricky to setup but there are plenty of examples via google

Windows there are various tools, some better than others but this works well: clumsy, an utility for simulating broken network for Windows Vista / Windows 7 and above

Check out this blog post: Finding Network-based Exploits - Unreal Engine

It details some console/config commands to simulate latency, packet loss, etc.
