Cisco ASA5550 Help

3 posts in this topic

Hello,

 

I have a firewall question that I need some feedback on. I recently inherited a network infrastructure that is not the norm or at least I have not seen this.

 

I have your standard Cisco ASA 5550 firewall configuration with an outside interface, inside interface and DMZ interface. The inside interface and the DMZ interface both have a direct connection to a Cisco 3750 switch. Is there a way to separate those 2 networks from not talking to eachother? Do I have to purchase another switch?

 

Thanks,

Do both network are connected to same switch? Are you running any VLAN on switch? If so you can setup ASA so that not to allow traffic between these vlans.

I would probably say that DMZ and INSIDE interfaces are on different VLANs on C3750 unless the previous admin did somtthing wrong mellow.png .
