SonicWALL VPN and local network

Archived from groups: comp.security.firewalls (More info?)

Hi,

We have a sonicwall pro 230 configured in front of our LAN switch
(an Extreme Networks Summit48si) to act as a VPN gateway to our local
network. All our VPNs are site-to-site mostly from Cisco, LinkSys,
Sonicwall TZW etc. The local network on the switch is
10.20.30.0/255.0.0.0.

One of the customers prefers to establish tunnels for just specific
hosts, instead of between networks. For e.g. they would like to allow
the tunnel to be used only for the host 192.168.100.200 on their
network from host 10.20.30.40 in our network.

The other customers are ok with network to network tunnel and they
need it too.

Half of this is simple, since I can setup my SA such that the
destination network is a network with mask 255.255.255.255. But I
have no way of specifying that the VPN should be established for the
local network (host). The SonicWALL tries to bring up the tunnel for
my whole subnet and fails since their firewall prevents it.

Is there a way to tell the SonicWALL to establish the tunnel for
just one host in the local network?
