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

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


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 ans 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:


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.

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 44.182.20.0/24,44.182.21.0/24,44.182.61.0/24,yo2loj.go.ro (adapt this list to your needs - commna separated, no spaces) -L your-call@AA00aa (optional)

~

~

~

<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 :-)


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


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