[Asterisk-Users] Firewall will definately increase jittersinyourvoice conversation

[Jonathan k. Creasy]

I didn't necessarily mean a separate firewall device, but I wouldn't put
a machine out there without a firewall either between it and the net or
on it (iptables for example)

As far as ""If" I know what I am doing" goes, I have not read the source
of everything that *is* required in my environment so how am I to know
it's secure enough not to allow for the creation of a backdoor, rootkit
or anything else? 

Therefore, even when I have taken all other security measures I also
lock down a box with a firewall. Usually, iptables, not a separate
firewall device.

That's a crack of crap sold by the marketing (not sales) people selling
firewalls. "If" you know what you're doing, one can very easily secure
any
linux system to function on the Internet (etc) without a firewall. It
all
depends on your level of knowledge/skills on how to disable those items
that are not really needed in your environment. Start with a 'netstat
-a'
to identify those ports that are listening, and shut those items down
that
you don't want exposed.

You "can" do the same for any MS system as well.
