Catalyst 3750: Transparent Firewall between VLANs

[Alexander Fischer]

Hi,

I'm very new to Cisco Switches and Routers so forgive the questions :-)

I have to put an ACL Firewall in front of a public IP range.There's no routing so I want to do it with a transparent layer 2 Firewall. I found this document which descibes exactly that feature I need: http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt_trans.html

It seems to be a feature introduced in IOS 12.3.

My Questions:

1.) is it possible use this transparent firewall feature with the 3750 Switch instead of a "normal" IOS-Based router?

2.) I've seen there is no IOS 12.3 for the 3750 but rather 12.2 (currently installed) or 15.0.1. Is this Feature included in 15.0.1?

If the feature described above is not available, is there any other way to achieve my goal?

Thanks in advance!

Best regards,

Alexander Fischer

Hi Alex

The firewall feature is no available in the 3750 series switches

If you need to use a device as a firewall than you need a router or you can use your 3750 and use an ASA firewall as your firewall
