Hi Everyone,<div><br></div><div>I have pfSense running which supplies Asterisk with DHCP. I had some testing ports opened for a web server which I have totally closed now but when I chose option 10 (filter log) on pfSense I get all of this type of traffic (note that it was only 1 single IP and once I blocked that one it was like opening a can full of bees with all different IPs):</div>
<div><br></div><div><div><br></div><div><br></div><div>tcpdump: WARNING: pflog0: no IPv4 address assigned</div><div>tcpdump: verbose output suppressed, use -v or -vv for full protocol decode</div><div>listening on pflog0, link-type PFLOG (OpenBSD pflog file), capture size 96 bytes</div>
