I have a rule in iptables to drop certain packets from addresses, like:
iptables --list | grep 37 DROP all -- 37.0.0.0/8 anywhere
So I am wondering how this got through???
[Jan 27 02:36:52] NOTICE[9298][C-000005ce] chan_sip.c: Call from '' ( 37.8.28.217:10024) to extension '888888011972592871997' rejected because extension not found in context 'default'
Shouldn't the firewall have dropped it?
That depends on the other rules. If there was a previous rule allowing access then the answer is no. But that's difficult to tell without knowing which rules are active so the output of iptables -n -L would help.
If you are not using fail2ban I highly recommend installing it and add/enable the asterisk rules.
