This may be off-topic for this list but perhaps someone could at least point me to a better source... When doing IPSec tunnels between Cisco routers it works nicely to first make a GRE tunnel which gives you a fairly normal interface that can run routing protocols, etc., then use 'crypto map' to push the GRE packets through IPSec encryption. Are there any examples available that would match this setup with Linux on one end, Cisco on the other? A Linux<->Cisco GRE is easy enough and zebra/quagga should run rip or ospf over that, but then I'd like to pass the GRE packets though IPSec before sending. -- Les Mikesell les@xxxxxxxxxxxxxxxx
