Nowadays there are lots of brute force attack and VoIP Fraud attempts targeting Asterisk and other PBX systems on the internet. It is a task of any systems Administrator to ensure success rate for such attempts is close to zero. One way to secure Asterisk such attempts is by using custom firewall rules.This will save you bandwidth and protect your business. To make our work easier, we will use a country based IP blacklist. We just built a service for a german client, he will expect customers from germany only, therefore we going to allow only german traffic to our SIP ports. Create a new file called germany.sh and add the following contents # Germany ipset -F sip.zone ipset -N sip.zone nethash for IP in $(wget -O - http://www.ipdeny.com/ipblocks/data/countries/de.zone) do ipset -A sip.zone $IP echo $IP done Execute the script chmod +x germany.sh ./germany.sh To get a list of countries that you can block or allow please visit https://www.ipdeny.com/ipblocks/ For example, to replace Germany with canada you will need to change this de.zone To this ca.zone Execute the following commands to allow the country you want iptables -A INPUT -s 127.0.0.1/32 -j ACCEPT iptables -A INPUT -p udp -m set --match-set sip.zone src -m udp --dport 5060 -j ACCEPT iptables -A INPUT -p tcp -m set --match-set sip.zone src -m tcp --dport 5060 -j ACCEPT iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT iptables -A INPUT -p tcp -m set ! --match-set sip.zone src -m tcp -j DROP iptables -A INPUT -p udp -m set ! --match-set sip.zone src -m udp -j DROP These will allow the following: Allow local connectionsAllow UDP,TCP connections to port 5060 from the country you set in your shell scriptAllow related and established connectionsAllow SSH from anywhereDrop all TCP and UDP connections not matching the country that you listed in your shell script Thats it, now you have installed Asterisk16 on Debian Bullseye.Your suggestions are always welcome!
