ASA and C3560 routing problem

Hi

I'm new to firewalls, so apologies if i'm wrong anhywhere.

Here is my setup.

I have a cisco C3560 switch with multiple VLans

It is connected to ASA 5505 which is further connected to Internet.

C3560 <--> G0/46 <--> 10.40.250.2 <--> 10.40.250.1 <--> E0/1 <--> ASA 5505

My problem is I'm not able to ping internet hosts from switch. Reverse route is fine. I'm able to ping switch and hosts on other Vlans.

And from switch I'm able to ping 10.40.250.1 (ASA interface). But from switch or my desktop i'm not able to go to internet.

Following are my configurations. Kindly help.

ASA and C3560 routing problem

Hi,

The ASA is lacking NAT configurations.

You can do the basic Dynamic PAT translation with either of the below ways

global (OUTSIDE) 1 interface

nat (INSIDE) 1 0.0.0.0 0.0.0.0

global (OUTSIDE) 1 interface

nat (INSIDE) 1 10.0.0.0 255.0.0.0

Hope this helps
