[SOLUTION/Summary] ..all my routing / VPN problems.
...0/24 never passed the
LOC interface of the FW, but rather injected directly into the switch), it
dropped the (as it thought) erranous packages silently (This would have been
seen if LOGNEWNOTSYN had been enabled in shorewall.conf.
Also: I chose to do "echo 0 > /proc/sys/net/ipv4/conf/eth1/send_redirects"
in the startup of shorewall to prevent the FW of redirecting hosts directly
to the VPN routers. This was done to be able to "enforce" policies in the
FW. (Yes, users COULD add a route themselves, but that is not a big consern)

Routing cache and the missing redirect flag
...che" does not show flags at all).
Here is what I do:
We have machine A with ip 192.168.0.121.
We have machine B with ip 192.168.0.10.
On a machine A (192.168.0.121) I ran:
route add -net 192.168.0.10 netmask 255.255.255.255 gw 192.168.0.189
The 192.168.0.189 machine, has forwarding and send_redirect set to 1.
machine A (192.168.0.121) has accept_redirects set to 1.
Now I run "ping 192.168.0.10".
I get a redirect: (as should indded be the case under these circumstances):
PING 192.168.0.10 (192.168.0.10) 56(84) bytes of data.

I would like to solve the following problem. Btw, I''m terribly
