Correct. If you read the VPN-1 .pdf for r-55 you can see the
restrictions imposed for doing VPN routing.

All,

Well, I just realized that the VPN license attached to my FW is for
secure
remote, and not secure client.  Even though you can go through the
motions,
I assume that I can't do what I am attempting with secure remote.  Or am
I
wrong.  I've stopped attempting to make this work until I can get
clarification.  Anyone?

Thanks,

-Lyle

Well, I have both ends defined for hub mode, no additional routes except
the
default routes for the interfaces themselves.

Destination     Netmask                 Gateway         Metric
Interface
x.x.x.0         255.255.255.192         0.0.0.0         0       eth0
10.157.63.0     255.255.255.128         0.0.0.0         0       eth1
10.157.63.128   255.255.255.128         0.0.0.0         0       eth2
default         0.0.0.0                 x.x.x.1         0       eth0

There's my routing table.

Now, with everything default like the above, and hub mode configured on
both, it times out @ the firewall when I attempt to trace or ping
anything.
It's almost like it doesn't know where to send the packets, yet I
figured
that's what the hub mode does.  In hub mode, should I define a
encryption
domain since its going to route all traffic through the FW anyways?

Anything else I can try.

It depends on what your gateway default route is.

In hub mode, all clear traffic to the Internet from SecureClient is
routed
from the Internet to the gateway and back out the gateway external
interface, just like you want. And it works because I use SecureClient
and I
can ping and traceroute to Internet sites when connected in by
SecureClient.
Since you don't have any desktop rules blocking anything, this leaves
routing as the prime suspect.

Are you using Office Mode? If not, what would the IP range be for the
source
of the hub mode packets leavingthe firewall & how are they routed back?
