[Freeswitch-users] Been hacked - what's the best way to prevent sip scanner?

[Mario]

I have a Linksys firewall and use NAT. The thing that's puzzling is even
with the natting how someone could get through to the natted address of
FS. It worries me that the phone system could be killed this way.
Anyway, this was a GoDaddy address and I reported it, they finally
killed it a little while ago. BTW, never could get Asterisk to work with
NAT but FS worked first time which is why I went with it.
