ASA 5505 to allow internet from external vlans

[vgiyenko]

Hello all.

I am facing the following issue: I have a layer 3 switch (3560) with multiple VLANs. The ASA (8.3) allowes internet access to only one VLAN at a time. I attempt to configure the ASA 5505 to allow all these VLANs access to the internet.

Any help is welcome.

Hello .

Yes you can do the same . For that you have to do the NAT for these VLAN's.

Rest depends upon your connectivity , distribution ou your subnets , Interface created on ASA.

Thanks

Hello,

As vishad said this is supported.

You could do this if the ASA connects have multiple interfaces connecting to the Vlans.

nat (any,outside) after-auto source dynamic any interface and that will do it

If the ASA only connects to the inside for the entire vlans (using routing) do

nat (inside,outside) after-auto source dynamic any interface

route inside x.x.x.x .x.x.x.x IP_Address_L3_Switch  (For all of the vlans)
