Hi Chris,
Life at Ofcom has overtaken amateur radio activity almost totally for the
last 3 1/2 years but I'm starting to "emerge" again, I'm sure that you
understand life's nasty way of getting in the way of hobby time.
A number of D-STAR services are still hosted on my servers, including the
central dsync reporting tool ( http://dsync.dstar.info/ is the public
reporting page but there is an extensive admin portal too) and also some
reflectors including REF006 ( http://ref006.dstargateway.org/ ). The
servers are due to be re-homed to an A&A data centre, where a few of the
staff are amateurs. Some of the D-STAR gateway admins have previously asked
about accessing services via ampr.org IP addresses; do you think that this
would be an appropriate use of the resource?
Tentatively I asked A&A if they could BGP advertise a subnet of ampr.org
and they'd be happy to do that, so it's more of a question of whether
D-STAR services for hams would be okay to provide via AMPRNet? Are there
any rules that would prevent the dsync pages being dual homed via public IP
space and ampr.org IP space? Has anyone managed to regularly route digital
voice (UDP) over AMPRNet?
Sorry for all the questions but I know that you will know the answers...

> With the BGP advertisement my subnet is reachable via internet and can reach anywhere via internet. Other 44 networks can reach my subnet as long as they are also advertised via BGP or have appropriate NAT rules to allow internet access. I can reach any BGP advertised 44 net addresses. However, I should not be able to reach any non-BGP advertised 44 net addresses unless there is a gateway (at USCD?) that allows for access to IPIP only 44 networks from 44 networks.

When the system that handles the traffic that comes in on your BGP advertised route also has a public IP address and is made member of the IPIP mesh for the same subnet it advertises on BGP, you can talk to everyone that is on the IPIP mesh.
They will send traffic for you via the IPIP tunnel that they establish because you are in the list maintained via portal.ampr.org and transmitted using RIP from the gateway at UCSD.
You then only use IPIP for traffic between hosts on the IPIP mesh, not for the remainder of traffic to and from internet.

Hi,
I received a 44 net allocation and am successfully advertising it to the internet via my ISP.
I have been reading on the AMPRNet Wiki about IPIP tunnelling and Startampr. Are there best practices or anything else I need to be aware of before venturing into building the gateway?
On a related note, I have been using OpenVPN to provide publicly routable /32 IP addresses to individual Windows PC. I don’t see support for IPIP on Windows, are there any other tunnelling methods worth looking at, for Windows7 specifically, or is OpenVPN my best bet?
Thanks,

Hi,
I wouldn't normally post here about this, but I see a couple of others
seem to have gotten a response from doing so.
I am new to amatuer radio and while I was getting my license someone
told me about APRMnet, so I decided to join. I put in a network
request back in november and got a response from the coordinator G1FEF
asking for clarification on my request. I responded via the portal,
however that has been the last I have heard.
I sent a follow-up email directly at the beginning of January, however
I haven't had any further response.
What should I do next?
Thanks,

Greetings!
I have a /22 block of AMPRNet space. I've configured it for tunnel access, and defined the gateway in my portal. Following the instructions on the wiki, here is my router config:
interface GigabitEthernet0/0
ip address 44.48.8.1 255.255.252.0 secondary
ip address 96.82.54.108 255.255.255.240

end
interface Tunnel0
no ip address
tunnel source 96.82.54.108

end

At this point, I believe I need to get RIP running with the right options. However, this is where the wiki falls short. The only rip configs examples are for the linux daemons. Here is the output of 'sh ip prot'
amprnet-router#sh ip protocols
*** IP Routing is NSF aware ***

As is standard practice, I've put all interfaces in passive-default, and then explicitly defined tunnel0 as non-passive. I have not been able to establish any sort of RIP adjacency:
amprnet-router#sh ip route rip

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is not set
amprnet-router#sh ip rip database
44.0.0.0/8 auto-summary
44.48.8.0/22 directly connected, GigabitEthernet0/0
Thanks in advance to anyone who can offer any guidance.

It is advisable to make your system an IPIP tunnel gateway for the same subnet as you advertise via BGP.
Make sure you use a non-44 public IP for the tunnel.
> On a related note, I have been using OpenVPN to provide publicly routable /32 IP addresses to individual Windows PC. I don’t see support for IPIP on Windows, are there any other tunnelling methods worth looking at, for Windows7 specifically, or is OpenVPN my best bet?
We offer OpenVPN but beware: it allows an easy entry into the AMPRnet that has nothing to do with
amateur radio anymore. You just become a VPN provider like there already are so many on internet.
To do something amateur-radio related with AMPRnet you really should offer radio access and encourage
the users to use it, and OpenVPN works counter-productive in that regard.

Hi,
I am interested in accessing 44 Net number via BGP. What would be the best avenue to discuss this? I already sent a message using the “Contact Us” link on the portal. How would I go about it?
Thanks,

I am the Utah coordinator. Based on the inquiry I checked my spam mail and
found what I believe is the subject request. This will be processed shortly.
Sorry for any inconvenience.

How long does it usually take for the coordinator to approve requests? I know the holidays will get in the way. I'm just wondering. I'm looking for some space in Utah.
Thanks.
Is there someone from there on this list? If so please contact me
offlist. Thanks.
