Re: isolate internal net on port 4 asa 5505

Create a new vlan interface and assign it a security level between your outside (100) and inside (0).

int vlan

name-if

security-level 50

ip address x.x.x.x m.m.m.m

Then assign port 4 to the new vlan.

int e0/4

switch acc vlan

Add nat to get to the internet

nat () 1 0 0

Depending upon your license you may also need this under the vlan interface.

no forward interface vlan
