Interface ens3 is the interface with public IP. I create an interface ens3:1 with my AMPR IP 2. You need to register that public IP wit the portal I have setup my public IP with amprportal 3. After 30 min or so, on that public IP you need to receive IP proto 4 The find_pass.sh could receive the password bradcast now traffic, at least the once every 5 minutes (the RIP broadcasts) 4. Next you need to set up a point to multipoint tunnel interface I have setup a script to create the IPIP tunnel. Attached below. Let me know if something isn't right. 5. You need to run ampr-ripd on that tunnel interface to receive the RIP broadcasts. Ampr-ripd will set up all your additional routes as defined in its command parameters 6. you need to setup a local networtk interface according to your allocation, where the gateway will forward the 44-net trafic to local machines So in your case you may listen to ens3 as long as you wish. The correct command to check for RIPv2 messages is: ampr-ripd -d -v -i ampr0 Where is the ampr0 interface come from. I could create one in /etc/network/interface. I only have one network interface. The incoming ampr0 traffic is seen on the interface ampr0, not on ens3... Ens3 in your setup is for connecting your local machines...
