Hi,

I have three local nets (192.168.10.0/24, 192.168.49.0/24,
192.168.61.0/24) and three monowall routers.  The first router (4501,
monowall 1.1 with NAT) connects the "backbone" net (192.168.10.0) to the
Internet via DSL. Router 2 (4526, monowall 1.1 without NAT, sis0, wi0)
is the connection between the backbone and the wireless net
192.168.49.0. The last router (4526, monowall 1.1 without NAT, sis0,
wi0) connects the wireless net and the wired net 192.168.61.0. Everthing
works fine, it took a bit of time to find the switch to turn off NAT 
(Enable advanced outbound NAT- checked).

Now I would like to secure the wireless net with ipsec. I have read the
article http://ezine.daemonnews.org/200401/wifi-ipsec.html, the section
ipsec from the FreeBSD handbook and the VPN setup of the monowall.

Is it possible with monowall 1.1 to make a configuration like is
suggested in daemonnews article (IPSEC tunnel)?

Thanks for helping,

best regards,

Harald
