vlan pc cannot access to internet

[sokmeng.min]

Dear all,

I got a problem with my lab. In this lab there are 1 ASA 5510 (filter internet) and core switch 3560X (for VLAN). I connected and configure the ASA5510 and core switch to each other, as diagram in attachment file, and these device can access internet properly, but the PCs which connected to core switch cannot access inetrnet. This is the diagram and some detail.

Please give some advice to solve this problem. Thanks in advance

Hi,

You have 3 vlans (1, 2 and 3) and you are only showing the config for vlan1. Are the other 2 vlans configured with SVIs just like vlan1?

Is firewall doing NAT?

Dear sir,

Thanks for your reply. Now my vlan client can access to internet, the problem cause of NAT on asa. Firstly, I allow NAT to only one range ( VLAN100: 192.168.100.0/24) which I use to connect from core switch to ASA and now I was change NAT to 192.168.0.0/16 and it work fine. Thanks again for your helpful support.

Best regard,
