SAT/NAT with original sender IP (DFL-800)
« on: August 04, 2010, 02:07:35 AM »
Hello there. I have DFL800 with several publishing services, our friend Alexander (danilovav) helps me with them... But there is one little problem... Mail publishing service with nat (sat) is working good, BUT everyone from WAN who send connection to SMTP, have success connection to our mail server, with IP like LAN_IP of DFL800. And our mail server receive lot requests from one single IP (lan_ip) ... How to change that, senders to have their original IP, and in that way to filter blacklisted senders, spammers...

Thanks to all!

Special thanks to danilovav:)

Use Allow instead of NAT :)
But in this case, DFL should be default gateway and server's firewall should accept any incoming connections from outside.
