Configure tunnel on Pfsense
by Tal Raveh 22 Feb '16

22 Feb '16

Hello, I'm trying to configure my gateway to 44 net on my pfsense FW. I configure GRE tunnel: Remote tunnel endpoint IP address:169.228.66.251 Local tunnel IP address: 44.138.2.254 (my segment is 44.138.2.0 ) Remote tunnel IP address: 44.0.0.0/8 Mobile encapsulation: check (also try to unchecked) The firewall is open but i cannot ping any address on 44 net. any idea? Best Regards, Tal 4z7tal

ICMP: A small request
by Marius Petrescu 21 Feb '16

21 Feb '16

Since we are trying to tackle connectivity problems a lot of times, could you please enable ICMP replies on your gateways, at least for other 44net requestors? It will certainly not ruin the gateway’s safety and security and would help a lot other OMs. Tnx, Marius, YO2LOJ

another OpenWrt gateway
by Daftcho Tabakov 21 Feb '16

21 Feb '16

Hi, I have tried to put my gateway in a new box - my tp-link 1043 nd router. I used to use an old pc with Debian for this purpose. I followed this wiki article http://wiki.ampr.org/index.php/Setting_up_a_gateway_on_OpenWRT and i can ping to different 44net IPs from the router's console. The gateway's IP is 44.185.22.1 аnd I would someone to test if it is reachable. I am also a little bit confused how my other devices will connect to the gateway. There was a pptpd server on the pc and it was easy. Now there is another VLAN on the router and I assume that I need to configure some of the lan ports (the switch) to use this new VLAN. This is good for the local connections. Can I use again pptpd and connect to my gateway from Internet like I used to do? -- 73! Daftcho, LZ1DAF

Please don't route regional subnets this way anymore. because then it can be reached both over radio and via the gateway. It is now routed with BGP to PE1RDP who will route it to the access point until arrangements have been made for a more direct routing. IPIP is still available for user subnets when you wish to route a network. > In its place I now have 44.137.27.193/32 in my allocation list.

I have corrected it (it belongs to PE5YES) Rob

And before anyone goes on about “open source” again, the code IS open source to the amateur radio community, just not the general public as it doesn’t need to be, if you want access to the code repository you only need to ask and it will be provided. Chris, I have brought up the topic of (impossibility of) editing subnets a long time ago. I have also reported the problem with registration of existing allocations (the user cannot specify what they want to register, only request a new allocation), and requested a way to delete open requests that cannot be completed. And a few months ago I requested that, facing the impossibility to delete a subnet without also deleting all its children and realizing that adding this may be nontrivial, you manually delete the 44.137.24.0/22 subnet that was erroneously created long ago, without deleting the subnets that are now under it. Apparently in the requirements and input you received the migration of existing allocations was not included. I seem to remember that this has been discussed and apparently it was downplayed as not important, but I don't agree with that. In my opinion, it should be possible to migrate existing allocations to the portal system when the holder desires to do that. Without such functionality, we cannot request all the existing users to register themselves and find out what to do next. I am doing a lot for the local amateur digital network here, and I have to select what other projects I join. I cannot be active in all of them. You have to understand that, contrary to some other areas, we are actively developing and using the network, and we require a system that works for us. So until now we have chosen to not register all the IP allocations via the portal, but only the required minimum that is the IPIP tunneled space, waiting for suitable functionality. In the DL/OE HAMNET the situation is the same, and there they developed their own system, HamnetDB. I understand that it is a spare time effort and other activities have priority, but we cannot live with a system part that keeps us back from progress forever. When there are problems or changes, there has to be some outlook that they will be fixed some day. Does not need to be tomorrow. Maybe you should join efforts with the HamnetDB people to merge the part that now handles the IPIP tunnel system with their system, which in other areas is much much more flexible and more like what we require. (although of course there always are wishlist items, e.g. because of things that are incompatible with our local license system) Rob

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?
