Subject: [44net] Using Cisco Router as a gateway ? From: Drorap drorap@netvision.net.il Date: 12/26/2015 10:22 PM

Hi there I have started to config a Cisco rouer to serve as a gateway for the AMPRNET I put in the command the following lines
interface Tunnel0 ip unnumbered Ethernet0 no ip directed-broadcast tunnel source Ethernet0 tunnel destination 132.239.255.131 tunnel mode ipip
Unfortunately due to the way tunnels work in Cisco and other commercial routers you will need to repeat that 300 times with different destinations and setup 500 routes to route the traffic, and repeat that regularly because the destinations and routes change all the time.
With a Linux system instead of the Cisco you can automate that very easily. There are possibilities to automate it on the Cisco (see that link Steve gave you) but still it will be a lot easier to just use a Raspberry Pi or other small Linux system.
