Hi guys, I'd like my Linux system to accept all ingoing TCP connections for any destination IP address on its single interface eth0. Roughly speaking, my goal is to emulate the whole Internet. Currently, the system serves as a brige between some LAN hosts and the Internet gateway. I have two further requirements: - the LAN host configuration may not change (currently, they have a fixed gateway and default route to the Internet gateway) - when simulating a connection, the original destination IP address needs to be known A first approach I made was creating an alias on eth0 for any destination IP. However, this is impossible given the large amount of possible IPv4 adresses. A next approach would be using NAT (e.g. iptables) and rewriting all target IP addresses to a single IP address. However, then the original target IP adress would be lost when accepting the connection via a socket. Do you have any ideas in mind you I could solve the situation? How to transparent application-level proxies perform this task? Thanks for your help in advance!
