Hello, all! I want to make DNAT (Destination NAT) on FreeBSD 5.3 with saving of source IP in translated packets. As I understood, natd always changes source IP to value of "-alias_address" or IP of "-interface". As I understood, remaining source IP unchanged possible with "-proxy_only". But "proxy-only" works with TCP traffic only, but I want to process UDP traffic via natd. Please, give me some advice how I can to do this. Thank you beforehand! The Schema: srcipA-----> ipB(DNAT)------->dstipC Now I using redirect_address, but I want to see in server's logs at dstipC original client's ip address (srcipA - is a pool of 30 addresses). -- Sergey Vavilov, Perm, Russia
