I am pretty new to the configuration of a DMZ and I have the task of setting one up.
I have a Cisco 2811 Router running Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1, RELEASE SOFTWARE (fc3), 2 FE interfaces.
One FE is connected to the WAN, with a loopback interface configured with the public IP for Internet access in the office.
The other FE has 2 sub interfaces configured, one for data and the other for voice traffic.
Users within the office are configured to use the data VLAN to access the internet through the WAN.
Now we are setting up some new services and we require to have DMZs setup.
I want to setup 3 zones now that the different servers would reside in. How can i achieve this using the existing infrastructure I have?
I have an idea to create more subinterfaces and assign them to the zones, but I am still not sure how this would play out. I have been on this for the whole day and unable to make significant progress. Would appreciate any help and guide what so ever.
Thanks for the suggestion and the link. Though I was looking for a more definitive step-by-step guide that could help me arrive at the goal faster. I'm not familiar with firewall rule setup, but will see what I can do tonight based on URL you sent.
So what I did was to create multiple VLANs and corresponding Security Zones on the router. Each VLAN was assigned to a Security Zone. Using firewall rules, I resprticted traffic between the VLANs to meet the specific need of what i needed to achieve.
