My task is to build up new Data Center

I have a question on the build new Data Center - The requirement is have Vlan segmentation from Prod/App/DB and users - There is a suggestion from the team to used Firewall as routing and gateway where the Core switch remain unfunction at all. Total host for this new DC is around 200 server (Clas C/24) -


1. Does firewall allowed to do routing for enterprise network

2. Does any enterprise firewall can do routing to cater class c /24 subnet

It's depending on how you could like to setup your network.

I probably would suggest to put all your internal network behind a/pair of firewalls with different zones to ensure the layer 2 and layer 3 seperation and security. And using your core switch to do the non-firewall routing if you core switch is 4500 or 6500.

Hi Joe,

the answer is depend on you deisgn

are you isolating these groups in L2 VLANS and using first L3 gateway as a firewall to control the routing between them

or you might consider using VRFs and routig isolation with firewalls in between as well as described in the below link:

hope this help
