I don't run SIP on my Allstar node; however, I do have an Asterisk PBX that does run SIP. I took a two pronged approach. I use use fail2ban to lockout SIP bots that try to connect. I run another utility that is used to block entire countries. Both utilities use iptables to perform the blocking which use a few resources as possible. I occasionally analyze my log files to see where major attempts come from and adjust the blocks from there. I would like to block everything but allow just the locations desired; however, the allowed location are all on ISP DHCP addresses. The above have greatly reduced the amount of bogus traffic on the server.

Hello all..
Been looking through the old forums and trying to get a handle on how to add SIP extensions to my all-star box. We are currently running acid distro on our repeater and using the allstarlink auto patch service. I would like to be able to add a few sip extensions so when i am on my cell phone i can connect to the repeater and listen or dial my wife who is a ham on a different extension and ring her phone. The extensions do not have to have "outside access" for the auto patch as the extensions would be used for internal communication to and from the repeater or to and from other extensions i add . Example extension 123 (which would be a sip client) be able to dial 28079 which is the repeater. or a person on the repeater be able to dial extension 123 and have the sip client ring. I have a static ip address so i know that won't be a problem, just a little confused on how to add everything in the config files. Does anyone by chance have a good working example
they could share? I would try the other distro but everyone like the web trans idea instead of using echo link :)
Thanks for any help i could get..
Bradley
