I've been using Cipe for a VPN. All of a sudden, it's stopped working. I've checked everything and it boiled down to the fact that we're no longer receiving the Cipe UDP packets. I run tcpdump on the source systems and see them go out, and can't see them come in. I can see them go in the other direction. I've triple checked the iptables and the port is open. Even tried turning it off, but no joy. Even tried using other ports. They are just getting lost in the Internet somewhere. The only commonality I see from both remote sites is Comcast. Is it possible that Comcast is blocking unsolicited UDP packets? _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
