Each Internet zone will have its own ISP default g/w connection.
Symptoms & Errors:
Cannot set an Internet default g/w on the Trust vr, only can be done on the Untrust vr.
Cannot set multiple gateways
2 separate ISP connections can terminate on the same NetScreen-204 or NetScreen-208, by separating the virtual routers, so that one connection uses the default trust-vr, while the other connection uses the untrust-vr.
