1. Do your clients *really* need public IPs on the machines themselves, or is it sufficient if you use NAT and ensure that packets to some public IP reach a specific client, and packets from that client have the public IP when they return to the Internet? What protocols / services are you using which require public IPs on the client machines? >> Well my clients wants to use Voip / Webserver and other VPN applications . So they need public ip .
2. We can't answer your question in any detail without more information about the topology of your network, in particular whether your ISP provides a small subnet to you, terminated at your netfilter machine, or whether that subnet block can be routed across the netfilter machine so that thLet me explain on My LAN i have ip address - 172.16.1.1 subnet - 255.255.0.0 on My WAN i have ipaddress - 203.122.51.178 subnet - 255.255.255.240
Yes i have read many things , but didn't find the solution.
