These are the steps for setting up a fully functional AMPR gateway on Ubiquiti's EdgeRouter Light and EdgeRouter-X.


NOTE: THE SETUP SCRIPT DOES NOT SECURE YOUR ROUTER. YOU NEED TO SET UP FIREWALL ROULES YOURSELF.


We start assuming you have a complete working and configured router, that already has internet access (a configured WAN port and a local LAN).

For technical reasons, this set-up does not support dynamic assigned WAN addresses. If you have a dynamic IP, this setup can only be used in the primary router's DMZ.


1. First add tunnel interface. You need to reserve an AMPR address from your AMPR subnet for the tunnel interface. If you have a /32 assignement, you need to use that one, else pick an unused address. Use the name 'tun44' for the tunnel, don't be creative since the script depends on this name.

- Config Tree -> add tun44 -> Update List

- tun44:

address: <your AMPR IP assigned to the router, see above>/32 (this MUST be 0.0.0.0, no matter what, to allow P2MP connections)

description: AMPR GW

encapsulation: ipip

local-ip: <your WAN IP - ISP assigned or router's DMZ IP>

remote-ip: 0.0.0.0 (this MUST be 0.0.0.0, no matter what)

- tun44 -> disabe-link-detect, press + right of it to enable

- Press Preview and Apply

If you prefer to do it by CLI:

ubnt@YO2LOJ-ER3:~$ configure

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 local-ip <put the external ip>

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 remote-ip 0.0.0.0

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 encapsulation ipip

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 address <44net router ip>/32

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 description "AMPR GW"

ubnt@YO2LOJ-ER3:~$ set interfaces tunnel tun44 disable-link-detect

ubnt@YO2LOJ-ER3:~$ commit; save

2. Download your packages from here (read this section to the end...):

Find the EdgeRouter setup package here: http://www.yo2loj.ro/hamprojects/Ampr_EdgeRouter.tgz (mips64)

For the EdgeRouterX setup use this one: http://www.yo2loj.ro/hamprojects/Ampr_EdgeRouterX.tgz (mipsel)


In short, get it, unpack on the router and run the install.sh script.

Then edit your startup script if needed, and run it.


Now the details...


a. First, log in and become root (don't omit that '-'):

Welcome to EdgeOS

ubnt@YO2LOJ-ER3:~$ sudo su -

b. Now download the correct package as described in the links above and unpack it:

root@YO2LOJ-ER3:~# curl http://yo2loj.ro/hamprojects/Ampr_EdgeRouter.tgz -o er.tgz

(you should get some download stats here...)

root@YO2LOJ-ER3:~# ls

er.tgz

root@YO2LOJ-ER3:~# tar -xf er.tgz

c. install the package:

root@YO2LOJ-ER3:~# ./install.sh

d. edit the startup script to fit your needs. This is only needed if your router is behind NAT or you need to reject specific subnets. Edit only the -a options like below, don't touch the rest. If you want to have your position shown on the ampr map, also add the -L option using your callsign and your QTH locator ( -L your-call@AA00aa ).

root@YO2LOJ-ER3:~# cd /etc

root@YO2LOJ-ER3:/etc# vi ampr.sh

<press insert to start editing>

[...]

ampr-ripd -s -t 44 -i tun44 -m 90 -a 44.128.1.0/24,44.128.2.0/24,your.gw.com (adapt this list to your needs - commna separated, no spaces)

~

<press esc>:wq (to save and exit - yes, vi is strange)

e. Now run the startup script:

root@YO2LOJ-ER3:/etc# ./ampr.sh

(On router restart, this will happen automatically)

That should do it :-)

3. Optionally you can install a status page in the wizzard section.
