Basic Routing Problem

[soborno]

Hi,
I´m having an issue with routing.
Because I have a Vlan(it will only be one), I add an interface to me untangle box, and connect an untagged port to that interface, so far seems to work fine, as the untangle box is able to ping to the vlan subnet.

The problem here is that when I put my untangle box as default gateway of a PC, I can´t ping to any of the Ip`s I`m able to ping from the UT box.

It´s seems pretty obvious that has something to do with the "DMZ"a Name that appear when you add a new interface.
But since I don´t get it, I ask for your help.

Anyway, thanks for the help.

Regards,
Claudio

Also,
Note that I assigned Nat Polycies to each interface, wich each subnet as address.
And since it´s going to work as a second lan, I don`t apply any packet filter rules.
