Configure a Cisco SG300-10

Hi all,


I have a Cisco SG300-10 which I want to use for 2 subnets and  I need to configure to route one public IP to a local server at and another public IP to another server at  Could someone show me how to do this?  Thank you for your help.


Hello,I believe you are


I believe you are describing a situation where you want to NAT the traffic from two different public IPs to two different servers.  For that you would need a router that can do either port forwarding or one-to-one NAT.  The switch is able to do some layer 3 routing, but isn't really meant to be on the edge, and cannot do NAT translations between public and private addresses. You also won't have a firewall with just a switch.

I would recommend the RV180W, but it looks like your two WAN IPs may be in different subnets, and that usually causes issues with port forwarding or one-to-one NAT for alternate WAN IPs.

Since you want to use two different subnets make sure the router you get is VLAN capable, so you can setup a trunk link to the SG300.  

Thank you for choosing Cisco,
