IPTABLES script generation for VoIP related

Looking for a programmer to build a IPTABLES script we can use to block outside access and sniffers from entering our network.

We actually want to allow only a few external ip's and an internal subnet range to allow to access the system.

external ip: [url removed, login to view]

external ip: [url removed, login to view]

internal block: 192.168.0.0/21

subnet: 255.255.248.0

Bcast: [url removed, login to view]

all else should be blocked completely.

please also refer to: http://www.voip-info.org/wiki/view/Asterisk+firewall+rules

to ensure we are blocking scanners as well.
