First, your ignorehosts line has to be *after* the portscan2 line.

It is...

Second, ignorehosts ignores portscans *from* hosts, like your DNS
servers.

Thats what I wrote.

If you are getting 5000+ alerts from people scanning your proxy, then

When my proxy sometimes opens many servers at short time and recieves
many responses snort thinks this is a portscan! :))

you might consider putting a BPF on snort to ignore your proxy or
something like that.

BPF?! Blocking ...?
