Thank you to all that responded to my email, I made my request through the portal.
I would like to provide free tunnel services to any amateur that applies and issue 44net addresses to those who qualify. I also will be experimenting locally with RF.
I am currently connected to AT&T at 10gbits/sec, should be snappy.
Thanks!

Yes, this works quite well. I have the same setup here.
I have a colocated Raspberry Pi that is on the IPIP mesh using ampr-ripd in
the standard setup that is described on the WiKi, and it serves my subnet and
a couple of /32 addresses.
My subnet is tunneled to my home using IPsec in AH/Tunnel mode. Using AH
instead of ESP (as is usually used) reduces CPU usage, and encryption is not
required for this purpose anyway. At home I have a MikroTik router.
I do have a fixed IP at home so IPsec is easy, when you don't have that it
may be easier to use a VPN that does not care about addresses, e.g. OpenVPN.
I also run a couple of applications locally on the Pi, hence the /32 addresses.
Today, thanks to Marius' work, it is also possible to use a MikroTik router
instead of the Raspberry Pi. It may be easier to configure and is available
in rackmount formfactor.

Greetings. I'm somewhat new to the list and would like to join the network.
I am not able to get a static address from my ISP, well I could, but I'd
have to get a business account and my speeds would be a lot slower than
they are now. I'm considering getting a VPS or a colocated raspberry pi to
act as a vpn server and my point of presence to connect to my network via a
tunnel. A rough ASCII diagram follows:
(^^^^^^^^^^^^^^^^^^^^^^^^^^^^)
( IPIP/Tun0/VPN Svr <<--- )
( Ieth0 RasPi in DATA CENTER)
(vvIvvvvvvvvvvvvvvvvvvvvvvvvv)
I
(^^I^^^^^^^^^^) (^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^)
( Internet )====(>LinuxRouter/VPN/Tun0/eth2-->>44.98.63.0/29)

I
(^^I^^^^^^^^)
(IPIP @ SDSU)
( 44/8 )
(vvvvvvvvvvv)
My intent is to initilly have connectivity for a small LAN and then build
it out over AX25 for my local area. I've run linux as my router/firewall
(iptables and ipset) since 2012, but have not done much with "ip route" or
"route", tunneling or anything with bridging but I did play a little with
GRE and OpenSwan a couple of years ago. My thinking is building tun0/eth0
bridge and feeding that through the VPN to the distant RasPi which would
vbidge the other end of the connection to the IPIP tunnel.
So my question is this: Is what I want to do feasable as a way to get a
static address and act as an AMPR gateway? Any suggestions, hints or
approaches to prod me in the right direction to get me going would be
appreciated.

All,
KD5ZZH here. I currently run an ISP (AS 62744) and I would like to provide an exit bridge to the public internet and link the Tom Green<x-apple-data-detectors://0> County, TX area as well.
How does one go about getting a /24 out of the block?

Hello all,
It seems that the ampr-ripd daemon will be included into Debian by the
DebianHams group.
To be able to fit into an easy setup for all fellow hams, after
discussions with Brian Kantor and Ana C. Custura taking care of
packackaging it, we reached the following conclusions:
- The RIP password was never actually meant as a security feature, more
a validation mechanism
- Everyone having access to the RIP data can actually extract the
password by sniffing the stream
- Since access to the network implies a gateway registration, and the
RIP sources are well defined and restricted, the password could be ignored.
Now, as a result of these discussions, I made some changes to the
ampr-ripd daemon:
- the RIP password is now included into the source file. The RIP data
will continue to be validated against this password.
- the password option can be omitted, but is still there for
compatibility reasons and if it would be necessary to change the
password at a later time
- password discovery via debug mode still works
- a man page for ampr-ripd was added (Tnx. Ana)
You can get the updated ampr-ripd from:
Internet: http://www.yo2loj.ro/hamprojects/ampr-ripd-1.14.tgz
44Net: http://yo2tm.ampr.org/hamprojects/ampr-ripd-1.14.tgz
or from GitHub:
git clone https://github.com/yo2loj/ampr-ripd.git
Have fun,

Gentlemen, if we cannot discuss a matter calmly and rationally,
we should not discuss it at all. What we are after here
is light, not heat.
Incendiary comments are not welcome on this mailing list.
Control yourselves.

It would still be an option to merge the portal and hamnetdb...
Hamnetdb is much more capable when managing subnets, and it is open.
There is an issue with scalability (it always shows you all the data it has when first opening a page,
before you have applied a search filter, which really loads older computers), so there may be
surprises when all of the world's data is loaded into it.
The "gateways" functionality is not yet there, so it would have to be implemented.
But issues like the one that started this discussion are easier to resolve in hamnetdb because
every object has a list of maintainers, which the owner or a sufficiently privileged person can
modify. So you can easily hand over control over your subnet (e.g. to include it in a gateway)
to someone else without sysop involvement.

For me, the portal is not usable as the only registry of information, because it
does not do DNS and DNS is essential for the functioning of the network.
(not only because you want to name your system, but also because being in DNS
is used as a filter to allow traffic through the gateway)
So I need to keep two different registries anyway, and it does not matter how
much of the information is in the portal and how much is in my own database.
Furthermore, for allocating subnets and addresses I need an easily browsable
view on the existing allocations including comments like regional names, to be
able to decide where to put the new entry.
To me, a simple "hosts" file edited in vi gives more overview than most point
and click interfaces, including even that of the hamnetdb (which is way better
than the portal in this regard).
This solution also reduces the effort when making bulk changes like moving an
entire subnet, doing cleanups like I did some time ago, or even transfer of the
existing allocations into the portal. Sure they would be possible with a tool
like this but it would either need a lot more features (and thus coding) or it
would have to offer direct access to the database for queries.

I see the evidence as presented. What is presented is you have some
"mystical" reason you refuse to be open with your code. This is
unacceptable. Can you logically argue it is not?

Having 44net over a barrel with code which we cannot audit or extend is not
helping; It's holding us back.

Well, this issue is really there!
Recently I found that two users from the Netherlands had setup completely
bogus gateway entries, both stealing subnets belonging to others and routing
them to the 44.137.x.x address I have them as "the gateway external address".
Those were probably not malicious, they just did not understand the portal
and fiddled around a bit, and left it as it is once they did not understand
anymore what is happening.
I think the portal should not allow to route other people's subnets through
your own gateway without some consent from the subnet's owner, I think for some
time it was impossible to setup such entries, and people complained that they
needed this to route for others, and the check was removed again.

Administering national and regional subnets is a real pain, as it is impossible
to manipulate the subnet structure without deleting it first, and ownership
of an entry cannot be transferred.
We all know how hard it is to get anything improved in the portal.
For now, I advise users to not register their subnets unless they want to
do IPIP tunneling.
W.r.t. the processing of RIP and IPIP traffic, you can do a lot with a
properly designed firewall. On my systems I accept only IPIP traffic from
gateways that I received before via RIP, and I accept RIP only from 44.0.0.1
on the IPIP interface. Maybe it would be possible to also check if the
traffic came from UCSD, I'll have to see how to check that in iptables.
(probably can be done with marking packets when they come in from UCSD,
then check the mark when they arrive on tunl0)
