(usagi-users 02250) IPSEC over ipv4 examples

[David T Hollis <dhollis@xxxxxxxxxxxxxx>]

Does anyone have any good examples of setting up a USAGI 2.4.20 kernel 
to perform IPSEC over ipv4 (no ipv6 at all)?  All of the examples I've 
seen have been traversing ipv6 connections and throwing ipv4 along with 
it and in trying to hack them around to work for my needs, it's no dice. 
 I am trying to setup a site-to-site tunnel (both sides are USAGI 
2.4.20, 2/14 release).  The problem that I am running into is that I can 
establish the IPIP tunnel and things are fine and tcpdump shows the 
traffic is not encrypted.  I can establish the IPSEC SA (IKE or manual) 
and everyone is happy but I can not route to the other side.  If I try 
to make the tunnel device the gateway, traffic goes but doesn't encrypt. 
 It seems that in connecting the tunnel to the IPSEC connection is 
where my problem is at.  But I can't tell.   Any pointers would really 
be appreciated.

Thanks.
