Hello
I'm a network administrator and I need some advice.
I have a small network with a Cisco 2516 router, several servers and
lots of hosts. I also have a small range of public IP. I can't give a
public IP to every host, because I don't have enough. So, the question
is How can I organize the network?
I have thought two possibilities:
A: Using NAT for servers and hosts. Static NAT for Servers, and
NAT-PAT for hosts. This can improve network security, but the servers
need to use multimedia, and I don't know if there could be some
problems with NAT and ports. In this case, I will use an Ethernet
inteface as usual.
B: Configure two subinterfaces on Ethernet interface, with two
different addresses. Host will use private address and router will do
NAT . The other address will be public and the servers will have
public addresses. Do you know if this could be possible?
Which one could be possible or better?
Thanks in advance

this is the way i would do it. Use a private class address for your host and severs. I assume you have connection to the internet. Use NAT and PAT for your outgoing connections to the internet. For devices accessed from outside the network use static nat.
thanks

A looks to be simpler to implement. You can try it first and in case you encounter problems with protocols running on your servers you can try B. With B you'll lose three of your valuable legal IPs (subnet address, subnet broadcast address and router interface address).
