IPCOP DMZ Domain Server

Hi people.

I replace my old (working) linux iptables firewall by IPCop to test in my network:

RED: ISP static IP (DNS Cache, DHCP)
GREEN: - GW: (PCs, Notebooks, etc)
DNS1 and DNS2 are from ISP for RED/ORANGE and RED IP for GREEN. (Work fine)

The problem is: From outside network can't resolve the domains on DNS server.

Any internet DNS Lookup tools show:

No name servers found for
FAILED. Parent servers not have A records for

With my old linux firewall DNS lookup work fine.

I tried forward 53 port to ORANGE but IPCOP show the following message: External port reseved for ipcop use


How to forward to my DNS Server in DMZ with IPCOP?

Thanks in advance
