Here is an idea on how they are building out their network in Slovenia.<br>
Maybe there are some good ideas that will catch your fancy.<br>
<br>
<br>
Maybe a concrete example of our current and future S5net in Slovenia <br>
together with our expectations from broader 44net community could help.<br>
<br>
As you can see from schema of current and planned links:<br>

<br>
we are building nationwide radio network, linking our hills with DMR <br>
repeaters into a fully redundant network, as much as possible <br>
independent from public internet. Main goals:<br>
<br>
- reliable DMR, EchoLink, APRS network,<br>
- emergency communications for our communities,<br>
- for radioclubs and individual radioamateurs,<br>
- open for experimentation and innovation into the future.<br>
<br>
Besides mesh-like radio layer there is also a star-like ground layer <br>
connecting gateways to public internet via tunnels to main router in our <br>
capital. VPN server is established to connect easily and from everywhere <br>
to the S5net. Offering L2TP and SSTP VPN access which is easiest for <br>
most people.<br>
<br>
We are using Mikrotik routers and Wifi antennas from Ubiquiti and <br>
Mikrotik. But we care not to become too dependent to any vendor. <br>
Sticking to standards is a key here.<br>
<br>
We allocate our 44.150 IPs in the following way:<br>
<br>
- /28 with reserve /28 to each hill,<br>
- /24 with reserve /24 to each interested radioclub,<br>
- /28 with /28 to a LAN of each interested radioamateur,<br>
- static /32 and dynamic /32 (like for mobile phones) to each interested<br>
- more for specific needs (for experimentation, some IoT projects etc.)<br>
<br>
Allocation is not forever, it will probably cease 5yrs after inactivity.<br>
<br>
OSPF protocol routes traffic in S5net. Therefore we are free to raise <br>
any subnet anywhere in the network. For things like roaming..<br>
<br>
BGP to the public internet for a whole national 44.150 allocation is <br>
something we are thinking about. Like in Netherlands as I understand? <br>
All access from outside disallowed by default, switched on manually for <br>
each individual IP or subnet.<br>
<br>
For peering we are talking with our Academic network ARNES, because they <br>
are similar in philosophy and have a lot of knowledgeable networkers <br>
willing to help.<br>
<br>
To interconnect with HAMnet in neighbor countries we also plan to use <br>
BGP with a whole S5net as one AS with private ASN.<br>
<br>
Our DMR master server is multihomed - with public access for hotspots <br>
and with 44 IP via S5net for DMR repeaters.<br>
<br>
Hope this helps a bit<br>
