[Openswan Users] "Promisc" trafic over tunnel

[Peter McGill]

Well IPSec (not just Openswan but the protocol in general) won't let you 
do that. It only transfers packets over the tunnels which match the 
tunnels source & dest subnets, and works with normal routing methods to 
do it. What your suggesting won't work with that. You could instead use 
tcpdump to capture the packets to a file, then periodically rotate the 
file and send it to the other host over the tunnel. Where you could then 
use tcpdump again to view the packets in the file. What you transfer the 
file with is up to you, sftp, ftps, ftp, etc...
