To setup a Gateway you need to have mikrotik router (all models support IPIP by default)

The example here will show the router that the WAN Port is connected to the DMZ of your Main router (the one that you get the ISP from it) and the 44 Net will appear on the Lan Port (wan and lan Referring to a home router model)

The configuration can be done with the web interface (webFig) or in manual text command with telnet or SSH connection to the router

At first assign 44 Net address to your router Interface You do it by the web  : IP --> Addresses --> Add New , a new screen will open , fill your 44 Net IP sub net (usually it will be /24) feel the network it should usually be same as the IP but with 0 in the end

Now chose which interface you assign this IP for , there is a drop down menu that show all of your interfaces , chose the one that connected to the local net

Now a tunnel interface have to be created between your router and the main AMPRNet router

You do it in the web by this : interfaces ---> Add New --> IP tunnel , a Screen will open

Change the name to say UCSD

Fill in the local address field your router address on the DMZ (in home it will probably be 10.0.0.x or 192.168.1.x)

At the remote address fill the address of the AMPRNET router (

Press the apply button and you are done

The Command in command line interface (via Telnet ot SSH) is as follows

/interface ipip
add allow-fast-path=no !keepalive local-address= name=UCSD \

Now some routes commands needed to be done

1) Route all the traffic to the tunnel interface

You do it by : IP --> Routes and clicking on the line and changing the gateway to the tunnel interface name and clicking apply

The command line in text is as follow

 /ip route
add distance=1 gateway=UCSD

2) route command for the tunnel to go to the InterNet

You do it by the web as follows : IP ---> routes ---> add new

at the screen , type in the destination address and at the gateway , type the ip address of the next router (for home network , it is usually or

The command line is as follows

/ip route
add distance=1 dst-address= gateway=

Now you should have connectivity from your 44 Net to the rest of the world (but not to any other 44 net networks worldwide )

In order to have a full connectivity to the other 44 Net networks a tunnel (and corresponding route command) must be added for every 44 Net gateway

The MikroTik have ability to run an automatic script that deal with the routing to the rest of the AMPRNET networks

The script run inside the router and take care of all the routes

In general it listen to the routes advertisements send from the AMPR.ORG main router and translating it to routes commands to the router

The Script can be found here

The Commands to run it can be found here
