Re: [44net] Using Cisco Router as a gateway ?

Dear Rob I used to do it 15 years ago and it worked I even publishe the config file to the Gateways users group that time I did a bi directional tunneling to UCSD (that time it was called mirrorshades) and let him deal with all the neccessary routes unfortenetlly it was long ago and the network has changes and i have stopped to work in networking and forgot most of the cisco routers CLI commands What i have described in my config was a (what I think) establishing a two way tunneling to AMPR.ORG router (the IP of the destination tunnel is the Commercial IP of AMPR.ORG router) Im not sure that it is inough and mabe i need more commands Regards Ronen - 4Z4ZQ http://www.ronen.org ----- Original Message ----- From: "Rob Janssen" <pe1chl(a)amsat.org> To: <44net(a)hamradio.ucsd.edu> Sent: Sunday, December 27, 2015 10:10 PM Subject: Re: [44net] Using Cisco Router as a gateway ? > (Please trim inclusions from previous messages) > _______________________________________________ >> Subject: >> [44net] Using Cisco Router as a gateway ? >> From: >> Drorap <drorap(a)netvision.net.il> >> Date: >> 12/26/2015 10:22 PM >> >> To: >> AMPRNet working group <44net(a)hamradio.ucsd.edu> >> >> >> 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.
