Hi,
I have a pix that connects to another router (in my datacenter, out of my control)
the pix has default gateway x.x.x.163 and everything works fine.
I would like to introduce a router of my own in-between my pix, and my datacenter router, so that this router would be an extra hop in the network.
When I configure my router as below, and try to give ip address x.x.x.180 / 255.255.255.224 to interface vlan1 , I get the error message:
x.x.x.160 overlaps with FastEthernet4

Can't I give interfaces IPs from the same ip range so that my router can act as an extra hop in the traffic? I do not wish to do NAT.
