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? Thanks, Jerry
