When to be used:: Multiple Inside Devices are Identical Servers with Mirrored Content, which from the Outside Appear to be a Single Server
We define a pool of addresses containing the real hosts' addresses ending with "type rotary" making the servers available in round-robin fashion. The access list now permits the IP address of the virtual host, i.e. what the outside world thinks is the host address. So the virtual host is 22.214.171.124 (or any public ip address that is being used to host the servers), with the real hosts being 192.168.1.2 through 4.

**NOTE:- This translation is not bi-directional in nature. We will have to use a one to one static NAT to accomplish it. A "ip nat inside source static" kind of funtionality can be achieved with the above configuration using a single address in the NAT pool, but that would only work for outside to inside traffic.
Hi, I am still learning all of this stuff but this should be pretty straight forward. I am trying to configure a gateway of last resort for this lab I'm doing for school, I've created a static route every other way and they've all worked. For some reason ...
I have some 100b with older code 15/16.x and vMAnage will not recognize them. How do I manually update the code to 19.x or are there a series of commands to force it to recognize vMange? thanks in advance, Ben
Hi all, I have a Cisco C921-4PLTEGB currently connected to the EE network using its Cellular interface.I have one VLAN (VLAN10) setup to connect back to our corporate network via a tunnel. All traffic by default should go down this tunnel for DH...
