System they are on can be designated gateway. - Router A = ISP's router and default gateway to system B. - System B (our server) has /30 subnet used to link router A (one IP) and system B (other IP = xxx). - On Router A route/direct /29 subnet (our 6 IP's) to point to System B's main IP (other IP = xxx). - Place all 6 IP's from subnet /29 as aliases to system B and DNAT/SNAT internal IP's to them. All router A will now is that traffic is coming from that /29 subnet (those 6 IP's), and it will not care how they reached them. The response traffic will be directed/routed via System B's main IP and system B will accept them as it's own IP's and do what ever it is supposed to do. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...
