Hi, I am having an issue with someone accessing our server via a SIP/VOIP connection. I have changed my iptables rules to drop all UDP traffic from and too this IP address, but this traffic seems to still run through my server. These are the iptables rules that I current have on the server. -A INPUT -i eth0 -s 209.61.231.42 -p udp -j DROP -A INPUT -i eth0 -d 209.61.231.42 -p udp -j DROP Regards Jennifer Botten ETECH -------------- next part -------------- An HTML attachment was scrubbed...
