I have a Question. We actually have a Cisco 1812 Router and we're Switching to an ASA 5512-X. The Problem is, the ASA 5512-X only has 6 Ports. The 1812, had 8. All in use.
We need to translate 3 Public IP Adresses into our Private IP Adresses for our Servers in the DMZ. We also need the other Ports. Our Situation now is, that the 3 IP Adresses are translated from the Router. But with the ASA we don't have enough Ports for this.
My Question is, can I "forward" those 3 IP Addresses from the ASA over the BLUE Port (in my Picture) to the Switch (I think i need Layer3 for this?!) and the Switch does the Translation?
The Translation should be: Public IP A,B or C comes in from the Internet to the ASA, get forwarded to the switch and the switch translates it to the correct private IP. Public IP A to Public IP B.
I have asked this in another Forum and got the answer, that an ASA can't replace a Router. Yes this is right but we don't need much functionality.
We have 4 seperate subnet. One DMZ. And three AP with two different VLAN. Thats all. And you see, this er six ports. 4 for our subnets, 1 for WIFI (I Hope i can only use one for 3 APs) and 1 for DMZ.
Are their any other solutions? Maybe using a normal router? a newer one, not the 1812.
