It is still hard to convince some people they should not block all ICMP. At work I am currently trying to solve a problem caused by dropping the above ICMP packet combined with the "blackhole detect" misfeature that means the connection is not just completely breaking down (and the bad firewall operator noticing his mistake), but becoming much slower. As bad as a site that has IPv6 in DNS but not actually working... Rob

Daftcho, Your configuration appears to be correct; but you performed traceroute on your WAN IP address, and not the 44net IP. Attempt to perform traceroute using the interface argument: 'traceroute whatismyip.ampr.org -i br-amprlan' 73, - Lynwood KB3VWG

BGP stats for AMPRNet
by Assi Friedman 19 Feb '16

19 Feb '16

Hi Brian: I am curious about BGP routing; since the agreements all go through you, here are a few questions: 1) How many AMPRNet subnets are currently being advertised via BGP? 2) Do you have any notion if specific ISPs are more open to allow BGP advertising than others? 3) Have any AMPRNet users had luck getting BGP agreements with home class service? Assi

Absolutely. Anything using Internet Protocol should work. BTW, I was unable to traceroute you. Feel free to use: http://44.60.44.10/tools/trace/php-trace44.php - Lynwood KB3VWG -----Original Message----- Can I use again pptpd and connect to my gateway from Internet like I used to do?

Getting an IPIP gateway to work requires some understanding of networking and system configuration, and it is a lot easier to do it on Linux than on your Cisco. But in any case you will need to study the matter and learn how to solve problems. In fact, that is most of the fun. As soon as it starts working, it is time to move on to other things... When you don't like it, you have probably chosen the wrong project. Rob

It's a small island in the Mediterranean sea. It's a French "department".

I'm wondering if it would be possible to obtain a /16 subnet for our "country". If so, what > would be the requirements ? How many radio amateurs are there in Corsica, and how many of them are likely to be active on the digital network? There are 134 callsigns in the QRZ.COM list for TK*. Maybe only those that voluntarily listed themselves are there? I think other countries of similar population size got a /20 assigned... Not that we have a shortage of address space, and not that I want to withhold you a /16, but it seems a bit large. Rob

It is all much too complicated. Get a Linux box. Seriously. Or BSD when you like that better. With a few simple configuration steps you have an IPIP router that works automatically and does not need manual attention or complicated scripts to update its configuration all the time. MikroTik is ideal for use as internal router in a radio network: point-to-point links and user accesses, and running BGP on the private AS numbers. That is not the same as running BGP towards internet! To announce BGP subnets on internet I would recommend to get this service from an ISP. They know this matter because they use it to advertise their own subnets, and a good ISP can advertise your subnet to internet and statically route the traffic to your router. Rob

Ronen, I am with Tom on this. Cisco routers/Mikrotik have their place later down in the network. By far the most logical way to do an IPIP gateway is with a Linux box. Look into the the various single board computers, you don't need a spinning hard drive if you are worried about dish crashes etc. Brian Kantor runs the whole thing at UCSD on a dual-core 3.2 Ghz Xeon processor with two 1 GbE ports running a BSD variant on a Compact flash storage device, if I remember correctly.
