nat loopback rule on firewall

Posted on 2011-10-18

i am using a zywall usg 200 security gateway as the firewall to our network but am having some difficulty with NAT allocation

everything is working well as it is currently set up but devices like mobile phones cannot get email whilst connected to the wifi here.  i believe that this is because "Nat loopback" is not currently enabled.

when i enable it an error pops up stating that i cannot have the "original IP" in the mapping rule set to any as it might cause a conflict.

my question is what should the original IP be set to?  should it be our public ip address or something.

any help greatly appreciated

    I not familiar with ZYWall. We are using other brand. But I believe it is something to do with local IP - interface (port) binding.  You might created this local address to bind with "any" interface. May  be you can try to change this to map certain inteface only.
