Switchport and external IPs

[Vermes000]

Hi,

we have a cisco 880 with 4 ports configured as switchport ports with dhcp and nat. Now we need to change one of the ports to be a bridge for a computer with a external IP, and we don't have any idea how to do it. We tried to set a static ip for this computer and set no swithchport for this port but it doesn't work.

Hi Vermex000,

I don't have much information, about your WAN interface, whether it is connected internet or it is connected to your private-cloud MPLS.

I assume you want to redirect traffic coming to your external ip address to port in blue and so you make sure host connected on blue-port IP address in the same subnet range as "interfave bvi3" does as shown below.

Interface bvi 3
 ip address 1.1.1.1 255.255.255.0
 no shut
 exit

bridge 3 bridge ip

interface ethernet0/4
 bridge-group 3
 exit

Let me if this helps.
