asterisk users - Nov 2003 - Confused about Asterisk server with regards to Linux NAT Firewall

Hi all,

I'm confused as to where I need to place the Asterisk server with repect
to my Linux Firewall?  I've read thru the message archives but have not
been able to glean a clear answer.  My Linux Firewall is a RH9 running
IPTABLES doing NAT.

Here are my questions:

1) I want to be able to make and receive SIP and IAX calls(From sources
like FWD, IAXtel, iptel etc.).   I read in one message stating the
Asterisk server must have a public IP address for this to work.  Is this
the recommended configuration or does it work from behind the Linux
Firewall with ports DNAT'd to the Asterisk server?  If so, is there some
doc on what needs to be configured in the iptables?

2) If the Asterisk server does indeed have to be outside the firewall
with a public IP address, do my SIP phones also have to have public IP
address or can they be behind the firewall?

Thanks in advance,
Ed Rubright

The probably easiest solution is to put * onto your firewall machine. 
That way Asterisk can communicate with the Internet through your public 
IP NIC, and your clients behind NAT can use the 2nd private IP NIC.

Also on the budgetone phone calls to other sip phones sounds like a
robot and is very choppy on outgoing calls.

Subject: [Asterisk-Users] Bad echo on outgoing calls

I have just installed and configured asterisk I have been playing with
software phones and an analog phone plugged into a TDM card. I have one
line coming in on a X100P card. 

All calls between stations and even over the net to Digium however I
have just got a Grand stream Budgetone-101 phone and it works great
except outgoing calls over the phone line. This type of call is also
less than perfect on all other stations but not as bad as on the 101. 

Very choppy and almost unusable this phone is located on a switch with
the asterisk server. This phone has very good quality on incoming calls
over the same line. 

Any help would be greatly appreciated.
