needs some advice to secure my system
Yes, that is exactly what I mean. My VoIP carrier provides details of a /24 IP address range that they use on their side. Therefore all I need to do is filter those out at firewall level.
Does the above mean to find out the ip of the SIP provider I use and only authorising these ones?
Bob, Set inbound-acl on your provider/internet facing profile to the providers range: x.x.x.x/24. If you want "firewall" functionality you'll need to use another firewall or iptables. On Tue, Feb 7, 2012 at 10:11 AM, Bob Smith <gb10hkzo-freeswitch@yahoo.co.uk> wrote:
