For my Xbox to work properly, I need to have open NAT. I can do this by setting my router's firewall settings to minimum (letting all incoming and outgoing traffic pass). However, this option is not very secure and I would like the firewall on my router to be secure to the maximum. The description of this option is
Incoming strategy: reject. The remote administration settings will replace
the incoming security policy. Outbound Strategy: reject. Outgoing access
is authorized to the following services: DHCP, DNS, IMAP, SMTP, POP3,
HTTPS, HTTP, FTP, Telnet.
I've read online that I should configure a port forwarding for the Xbox to connect properly to Xbox-Live servers. But, no matter the fact that I have correctly configured the ports, I still can not get an open NAT. So I wonder
- Is it possible to get an open NAT when your firewall is configured for maximum security?
- Is port forwarding say nothing when your firewall is configured for maximum security? I've talked to my ISP (Verizon) and the technician said that port forwarding means nothing if you set the firewall on maximum security, but I think it's wrong , because that would not it impede the transfer of port?
The minimum security for the firewall reads "Inbound Policy: Accept." Outbound Policy: Accept. Am I right to worry about this level of security or should I just set firewall security to a minimum?
