Am a CCNP, have a pix 515 in my home lab. It has 3 interfaces which I have configured as follows: outside interface security level 0, internal interface security level 100 and dmz 50. static nat has been configured. but there is no communication b/w the interfaces. The command sh route does not display any connected interfaces. Can someone help me please? the version of OS is 7.0. Thanks. nakachukwu
