Sample Asterisk Firewall Rules

 

IPTables

This is an example on how to configure a Linux IPTables firewall for Asterisk:


# SIP on UDP port 5060. Other SIP servers may need TCP port 5060 as well
iptables -A INPUT -p udp -m udp --dport 5004:5082 -j ACCEPT
# IAX2- the IAX protocol
iptables -A INPUT -p udp -m udp --dport 4569 -j ACCEPT
# IAX - most have switched to IAX v2, or ought to
iptables -A INPUT -p udp -m udp --dport 5036 -j ACCEPT
# RTP - the media stream
iptables -A INPUT -p udp -m udp --dport 10000:20000 -j ACCEPT
# MGCP - if you use media gateway control protocol in your configuration
iptables -A INPUT -p udp -m udp --dport 2727 -j ACCEPT



More security

BEWARE: these rules can open the firewall completely. Test them.


# iptables -A INPUT -p tcp --syn -m limit --limit 1/s -j ACCEPT
# iptables -A INPUT -p tcp --syn -j DROP
