Question : Testing VPN on internal network

Is it possible to test a vpn connection using the following setup ??

10.10.10.1  ---- Cisco PIX 501 --- 192.168.1.205 <------------->192.168.206 ---- Cisco PIX 501 ------ 10.10.20.1

where the 10.10.X.X are the internal networks on the two ends...

if not is there a way to set it up to verify the settings prior to putting it into the client locations that are about 50 miles apart.. so I do not have to run back and forth...

thanks

As long as it is done internally, the above schenario should work just fine.  But bear in mind, that some things may be different on the locations (like a non-bridging DSL modem or the likes).
