interesting traffic meaning

Recommended Posts

Posted · Original PosterOP

Hi everybody.

Please, I would like your help in order to understand meaning of "interesting traffic" in networking.

Not specifically in NAT, VPN, etc. I cannot understand what it is in Ethernet IT.

Can you explain it?

 

Thank you!

Your question doesn't make much sense. What one finds interesting or not interesting depends on the situation, the environment and the person looking at it. There is no universal definition for what is or isn't interesting.

Yeah, your question is kind of confusing but basically "interesting traffic" would be any traffic that shouldn't or normally wouldn't be there like broadcast storms, a rouge DHCP server, excessive DNS requests or requests to a server that shouldn't be there, etc.

That's usually the context though.  Most VPN ACLs (access lists) that match 'the traffic you want' become 'interesting' when it matches the access list to be encapsulated within the tunnel.
