Hi, the problem ist he tcp profile wich uses PEN. The 443 not the smtp. Von: Mathieu Chateau [mailto:[email protected]] Gesendet: Montag, 15.

Hello, I guess it's incoming smtp, else your wouldn't see any relay attempt. Using L4xnat should make your server receiving real remote ip address. Then it must use zen as a gateway for reply. For SMTP, except if you only have 1 ip address, I do not see big benefits, as MX are already meant to survive smtp server failure in the whole internet. Tcpdump wouldn't be useful as you need the true IP in realtime to block smtp connection and not accept it at all. Also needed for grey listing. Cordialement, Mathieu CHATEAU http://www.lotp.fr 2015-06-15 16:44 GMT+02:00 Emilio Campos <[email protected]<mailto:[email protected]>>: You can use tcpdump in the load balancer in order to obtain the origin IP. 2015-06-12 22:54 GMT+02:00 Ernie Dunbar <[email protected]<mailto:[email protected]>>: Hi everyone. We're using the community edition of Zen Loadbalancer, and I've noticed a problem with logging incoming connections. Namely, that it doesn't exist. We've only set up POP and outgoing SMTP as a load balanced service so far, but as a result of that our logs are now filling up with a lot of SMTP relay attempts. Setting up Fail2Ban on the loadbalancer would be pretty easy, if only we had any idea where these connections were coming from, but they're not showing up in any of the logs. Is there some setting that can turn this logging on? ------------------------------------------------------------------------------ _______________________________________________ Zenloadbalancer-support mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/zenloadbalancer-support -- Load balancer distribution - Open Source Project http://www.zenloadbalancer.com Distribution list (subscribe): [email protected]<mailto:[email protected]> ------------------------------------------------------------------------------ _______________________________________________ Zenloadbalancer-support mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/zenloadbalancer-support -- ✓ Geprüft von IKARUS anti.virus http://www.ikarussecurity.com -- ✓ Geprüft von IKARUS anti.virus http://www.ikarussecurity.com
