I want to use pat on multiple vlans from our catalyst 4503. The vlan networks are 10.10.1.0/24, 10.10.2.0/24, etc. Would the inside (nat) 1 just be 10.10.0.0/16 on the pix? But the inside pix int is 10.10.1.2, so not sure that the /16 mask would work. If not, any ideas? Thanks in advance and if anymore info is needed, let me know.
