InterVlan routing in Cisco ASA

[Ejaz Ahmed]

Hi Experts,

I have an brand new Cisco ASA 5512-x and a cisco SG300-28P with me. I have to setup a network with four VLANs in my internal network(like office, Guest, etc). IN this some of the VLANs need to communicate with each other and other don't. Some VLAs need to communication only to internet. Can anyone help me how I can achieve this? I Also is it possible to configure inter-VLAN routing using a single ASA port?

Regards,

Ejaz

Hello, Ejaz. 

I recommend downloading the latest firmware of your SG300-28P first. What is your current firmware, by the way? Check the VLAN Mangement page for a detailed instruction on this guide:

There is also a similar/helpful discussion about setting up VLAN on an SG300 switch:

Do you also have support contract/SmartNet on your SG300 or ASA?

Let me know if you have additional concerns or e-mail (adawa@cisco.com) me directly. Kind regards.

Yes . you can config vlan subinterface and 802.1q trunking on Asa platform  , like the router.  Please refer to the website as following.
