It wouldn't affect your network at all. Your customers do something dumb, it's their own fault.

If they don't know how to do that. We log in to the radio and set the DMZ IP to whatever their router pulled from our radio. This setup works perfectly and we never have any problems with any services and generally only need to have people set their router in the DMZ IF they need port forwarding. With this setup the WAN port of the radio (WAN.1201 in the image) is not pingable and can not be managed from the internet. The only way we can manage CPE's is from the internal network. IF you want to access from the internet you'd have to uncheck the "Block Management Access" alternatively you may also need to uncheck the DMZ management ports. I can't remember. I do NOT want my CPE's to be accessed from the outside world in anyway shape or form. With our setup IF they need access to something inside this allows that to happen without having to bridge the radio. SIP, VPN, Games all work fine.

True. Perhaps what I need to do on the CPE is set the DHCP range for 1 IP addy and put that addy in the DMZ? Then the radio wouldn't inadvertently block anything.

That helps a lot! I have my customers in router mode with NAT enabled without opening any ports. I really dont get any complaints but I'm trying to be sure I am not causing any undo issues for my customers, so, should I open any ports or is default sufficient?

In router mode with NAT enabled and DMZ disabled the only thing it will pass to the customer is stuff that is set in the port forwarding section. (iptables -t nat -L) In router mode with NAT enabled and DMZ enabled it will pass everything to the DMZ IP except management ports (unless DMZ management ports is checked) (iptables -t nat -L will show all ports not passed to the router). If DMZ management ports is checked then everything is sent to the DMZ IP. In router mode without NAT enabled it will route all traffic to the LAN address space, this means you need to have a subnet on the LAN side that is routed externally to the radio IP address. In bridge mode all traffic coming in WLAN will be passed to LAN. On 11/26/2014 11:04 AM, RickG wrote: <blockquote> Thanks Sam!

By open that means those are the only ports on the radio that have something listening on them. If you turn those services off on the services tab then they will no longer be listening on those ports. You can also turn on SNMP (UDP 161) and telnet (TCP 23) To see what ports are being listened on use 'netstat -nl' from the command line, to see what ports are being forwarded you can use 'iptables -t nat -L' On 11/25/2014 08:27 PM, RickG wrote: <blockquote> I agree Mike, however my question is more basic than that. I realize that a UBNT radio comes with the firewall turned off and in fact I've never turned it on. So, my question is: Default from the factory, which ports are open and/or closed? Obviously most common ports are open. Do I need to open any to prevent any issues?
