log smoothwall

[elpollodiablo]

ho un router/firewall con smoothwall 2.0b4 che condivide una connessione adsl sulla mia rete casalinga. premetto che ho aperto una porta UDP e una porta TCP (emule) verso un pc che scarica in continuo.

ora, cosa diavolo è tutta questa spazzatura assortita che trovo di continuo nel log di snort ?
