im using asterisk 16.6.1 on ubuntu 20.04.2
im looking for the right configuration of fail2ban and iptables , im trying from many sources but still not working
im looking for source used and functioning correctly
(note: i use chan_sip not chan_pjsip)
Did you change defaut sip port already or not ?
no i Don’t change any port !
As a good security practice change sip port of your asterisk. You basically get 99% of attacks off your server.
For the other 1% I believe fail2ban can protect you.
im just looking for fail2ban configuration only for my graduation project
I personally don’t use fail2ban, but I would suggest
1/ stop living in the past and move to pjsip2/ https://www.redhat.com/sysadmin/protect-systems-fail2ban
3/ https://github.com/cleardevice/docker-asterisk-latest-pjsip-fail2ban/blob/master/conf/jail.conf
