Hello to Everyone,
New user here, so first of all, nice to meet you
Im using Zentyal as a Gateway (with load balancing) and firewall in my Lan. The configuration Im currently using is the following:
===== ADSL router (Zyxzel P600 series)=========================
Public IP [188.85.xxx.xxx].
Private IP [192.168.1.32] All ports forwarded to 192.168.1.100
===== Zentyal box ======================================
Network card 1 (LAN) 10.10.1.125, external*, conected to my lan (10.10.1.0) Port redirection: From 10.10.1.125:8080 to 10.10.1.1:80. works inside the lan
Network card 2 (Bridge 1) 10.10.1.100, external, physically conected to Zyxzel router Port redirection: From 10.10.1.100:8080 to 10.10.1.125:8080
Network card 3 (Bridge 1) 10.10.1.100, external, to be conected to a ADSL routerNetwork card 4 (Bridge 1) 10.10.1.100, external, to be conected to a ADSL router==== Local Lan ========================================
Ips rangin from [10.10.1.1] to [10.10.1.254], gateway: [10.10.1.125] (Zentyal), DNS [8.8.8.8]
What im trying to acomplish is to allow a machine on the lan (I.E 10.10.1.75) to acces the public ip of the Zentyal box using some port (188.85.xxx.xxx:8080), and be redirected to another port on a PC inside the lan (I.E 10.10.1.1:80).
I think this feature its called "NAT Loopback", but i havent found a way to get this done on Zentyal... Im not very literate on the use of iptables, and I couldnt find anything about this on the help pages...
I hope someone whith better knowledge than me coud lend me a hand...
*: this interface is declared external because it has a port redirection inside (8080 to 10.10.1.1:80) that wont work inside the lan if it was declared as a internal interface.
Thank you for reading my post.
