OK, let me get this straight.  You ask a question, and then get snippy
when some advice is offered instead of a specific answer to your
question?

Dude, you aren't paying us.  Get over it.

The fact that you CAN do it doesn't mean that you SHOULD do it.  There
is disagreement, even on this list; I don't think that you should.

>From the VPN Concentrator help screen
"Split tunneling is primarily a traffic management feature, not a
security feature. In fact, for optimum security, we recommend that you
not enable split tunneling."

That said . . . "split tunnelling" is the key term.  It is configured
in the GROUP settings, on the CLIENT CONFIG tab of the VPN
concentrator admin console, accessed by browsing to the concentrator
and logging on.  There is a bit more to split tunneling than just
turning it on; the online help from the VPN concentrator explains it
pretty well.  The settings can be made VERY specific, or there are
three "standard ones"
- tunnel everything, which is the standard
- tunnel everything except specific traffic - this allow local printing, etc.
- tunnel only specific traffic - this allows internet access at the client side
