[44net] Using a cisco to do the tunnelling

Ciao Sam in CisarNet (http://www.cisar.it/radiowiki/index.php?title=Italian_Cisar_Radio_Amateur_W…) we are already using with success a Cisco router to "Gateway" our wifi national network to amprnet 44.0/8, with a lot of tunnel interfaces configured by means of a visual basic script and batch commands running by a normal windows xp computer. This script is easily adaptable for your needings. Sorry for my delay in the answer, but I have some trouble in receiving correctly 44net mailing list. Please discard my message if this is not useful anymore, or feel free to contact me to share our scripts. Ciao from Italy. IW0SAB Renzo.

Cisco support only a single source and destination address for an IPIP tunnel interface. In other systems (NOS, Linux) the idea usually is that you setup a single tunnel interface and have a routing table that tells the system where to send packets for a certain subnet. But in a Cisco I think you would need to configure a separate tunnel interface for each gateway station. The problem is that the station list is not static, so you need to write some script that generates IOS config commands to insert, delete and modify tunnel interfaces to track the changes in the encap.txt. There are multipoint tunnels in IOS, like DMVPN, but those protocols are not in use in the amateur IP net. (unfortunate, because it could automate the entire encap.txt hassle and solve all problems for people with dynamic addresses) Correct me if I am wrong... We have an unused 887 at work that I would probable be able to get donated for home use, but I have hesitated to take the plunge. Rob
