Why using a vpn software for just tunneling data? If you don't want/need 
encryption then you should take a lot at iproute2. With this tool you are 
able to build tunnels over IP (without using tcp or udp). It uses it's own 
protocol, just like the esp/ah protocol from ipsec (but has nothing to do 
with encryption).

take a lot at: "ip tunnel help" and maybe: 
http://snafu.freedom.org/linux2.2/iproute-notes.html
But sadlly there is not so much information available for iproute2. Even many 
good administrators doesn't know this tool...

"ip" from iproute2 is a very very good replacement for ifconfig/route/arp + 
has some more functions like source routing, tunnel (even ipv6 in ipv4) etc. 
But iproute2 can nicely coexist with the old tools. You can even mix the 
commands up and for example add one route with the classical "route add" and 
one with: "ip route add" :)

But I am asking myself why tunneling all this traffic? If I got you right, 
then this gigabit/radio network has nothing to do with the internet. Why then 
not just routing the networks? Or have I missed something?
