<div style="RIGHT: auto">I just wondering if anyone has any experience to get Shrew VPN client working with ZyXel USG20W. I notice that there is another post for ZyXel USG already. I had followed the instructions step-by-step very carefully, however I get an error that said "Invalid message from gateway". The only different I can tell is that my ZyXel is model USG20W, but the one posted is USG300. The screen look identical. So, it must be something specific about this USG20W. I tried to use other VPN client too, and I got the same error, it seems like ZyXel send back some invalid command back during the phase 2 authication process.</div>

<div style="RIGHT: auto">I have attached the screenshoot from the ZyXel log file and the Shrew VPN client screen. Any help is appreicated.</div>
