I have to assign to customers public IPs form my ISP (32public IPs, /29 subnet). In a x.x.x.x/29 subnet only 30 IPs are available: x.x.x.128 is the network and x.x.x.159 is the broadcast. My customenrs stays behind MK.
ISP router as a public IP (x.x.x.129) and MK have another public IP (x.x.x.130) on the same subnet in order to communicate with ISP router.
The problem is that as I give x.x.x.130/29 to MK, a dynamic route is created and the whole subnet is considered reachable on that interface (let's call it WAN), while I want to assign public IPs of that subnet on another interface (e.g. AUTH). Is there a way that I can say to MK that the remaining public IPs (x.x.x.131-x.x.x.158) are on AUTH interface instead of WAN ?!?!?
Internet-----ISP ROUTER--------(WAN) MK (AUTH)----------- Customer
I want x.x.x.131 to arrive @ ISP router, not masqueraded. But as I give x.x.x.130 to MK, it think that x.x.x.131 is on the segment that looks @ ISP router.
