That above and this is what I suggest.
#1 Get one that supports IPv6 (as it is the future and makes no sense to upgrade to another NAT router that supports this if your current NAT router does not).
a) I point to and quote part of DSLR (dslreports.com) -> Forums -> Software and Operating Systems -. All Things Unix -> Windows 10: Another reason to use Linux!
As I stated in that thread I fail to see the point in using this program.
Why? Most routers today have a pretty simple GUI based interface to setup forwarding of ports for programs. And thus this program has NO USE.
IF you KNOW the ports.... Now there is the rub..... but here is also the part where users can learn something(s). Yeah I can rattle off ports/programs for the popular stuff, one cause I use it, and two stupid A+/Network+ ask you to fill out such stuff on their tests.
I would suggest creating a thread in the networking or software forum(S) and posting WHAT SOFTWARE this is, and most can probably tell you which port(S) to open in your router. Most routers have the basics for ftp etc. covered.. For some program I am sure it is just a google search away mostly to find the port(s) needed, or even using uPNP (although that would NOT be my choice, security risk) again simple GUI on/off in most consumer/low end SOHO routers.
Most will probably be glad to tell you the port(S) and post some screen snaps if needed to set this up.
Again I just don't see the purpose or need for this program?!?!?
b) Thinking about what I was told, they are correct.
#3 If you get a NAT router that supports wireless and since you do not want to use wireless, turn that feature off and leave off wireless in the NAT router until you change your mind (if you ever do).
#4 If you do not a wireless NAT router, if you change your mind (ever) then either:
a) Get a pure WAP (without a NAT router in it)
b) OR get a NAT router with wireless and convert it to act as if it was a pure HUB/Switch/WAP.
#5 As how to do that last step goes like this..
#1 In the primary NAT router:
a) Find the DHCP Range
b) You need to make sure that it's DHCP Range does not occupy the whole subnet.
c) If it does, you need to make it smaller.
For example if the NAT router's IP Address is 192.168.1.1, the first IP Address that it hands out is 192.168.1.2, and the last IP Address that it hands out is 192.168.1.254 - then you could change the first IP Address that it hands out so that it is 192.168.1.100
#2 With the secondary NAT router's WAN port not connected to anything else and not connected to the primary NAT router.
a) Change it's LAN IP so that it in the same subnet as the primary NAT router but outside of it's DHCP Range.
For example if the NAT router's IP Address is 192.168.1.1, the first IP Address that it hands out is 192.168.1.100, and the last IP Address that it hands out is 192.168.1.254 - then you could make it's LAN IP 192.168.1.2
b) Disable it's DHCP Sever.
c) Connect one of it's LAN ports to one of the LAN ports of the primary NAT router.
#6 So extra note(s) about the DHCP settings besides where they are/might be in the NAT router:
a) Even in the pure WAP allows you to use DHCP, it's LAN IP should be Static. This way you do not have to log-in to the primary NAT router and find it's DHCP Table (DHCP Client List) in order to access the pure WAP.
b) If you ever get more than one computer behind the NAT router (Game console: Xbox, Playstation, or Wii. Other dedicated computer but not a game console: dedicated print server or dedicated DVR come to mind. OR otherwise: Any other computer - Windows, Mac/Unix/Linux based) you should setup a Static IP on/for the computers that you want to host on.
c) Some NAT routers allow you to setup a LAN Static IP Address for the computer(s). This feature could be called Static-DHCP or DHCP Reservation. All it is, is to this computer by MAC/Physical/Host Address is to give it this given IP Address. You may consider getting a NAT router that supports this feature. Some require it/them to be inside of the DHCP range, others require it/them to outside of the DHCP range and others it does not matter where you put it/them in regards the DHCP Range.
#7 Besides the router offers or do not offer wireless, there is at least one other category. Hardware based (for example Linksys E4200) and software based.
For software based NAT router(s), I give to you the following links:https://www.dslreports.com/shownews/Exploring-DIY-Linux-Router-Distros-118897
(a bit out of date, since one or more has reached EOL).https://www.dslreports.com/forum/r30568002-Numbers-don-t-lie-it-s-time-to-build-your-own-routerhttps://www.dslreports.com/forum/r30714877-Guide-to-building-a-Linux-router-from-scratchhttps://www.dslreports.com/forum/r30984220-The-Router-rumble-Ars-DIY-build-faces-better-tests-tougher-competition
#8 If the NAT router that you get offers UPnP...........
a) As noted at http://portforward.com/networking/static-ip-ps4/
For Play Station it would be NAT Type 2.
b) As noted at http://portforward.com/networking/staticip-xbox360.htm
for the Xbox 360 it would be Xbox LIVE results should be "Connected."
c) As noted at http://portforward.com/networking/static-ip-xbox-one/
for the Xbox One it would be NAT Type Open.
#2 I have read/heard that if someone only has one Non Bogan IP Address the only way to get more than game console having NAT Type 2 / Xbox LIVE results Connected / Open is to use Universal Plug and Play (UPnP).
#3 I have no idea if what I read/heard is true or not about game consoles, getting NAT Type 2 / Xbox LIVE results Connected / Open, and only one non bogan IP Address.
#4 However, be advised:
a) If UPnP is enabled in the router
b) If an user has UPnP turned on, on their computer (Windows) / system (Xbox)
c) If an user has UPnP allowed by their software firewall on their computer.
d) and if an user has an UPnP aware app (for example uTorrent) on their computer.Then the user could open port(s) in the router without knowing the router's control log-in!
#5 If you find a server that you want to forward for is not UPnP aware, then I point you tohttp://www.howtogeek.com/122227/how-to-quickly-forward-ports-on-your-router-from-a-desktop-application/
With info about: UPnP Port Mapper
#6 If you do not want to use UPnP and you wanted more than one game console having NAT Type 2 / Xbox LIVE results Connected / Open then part of the answer is to get more than one non bogan / Public IP Address.
#7 If you do not know where the UPnP setting in your router is ( or what you want to get only one of them working - because you do not use both at the same time and OR you do not like UPnP ), it would help to know to know at least the brand and model of your NAT router.
For example of what I got: Brand = Linksys, Model = E4200, Hardware Version = 1, Firmware = Tomato Firmware v1.28.0508 MIPSR2 Toastman-RT-N K26 USB VLAN-VPN-NOCAT, Type of NAT Router = RJ-45 WAN (only one. not dual, triple, ETC....) port
... Since you only have one computer it makes sense to disable UPnP as you only need that if you have more than one game console to get NAT Type 2 / Xbox LIVE results Connected / Open with only one non bogan IP Address.
If you call that creepy UPnP on the LAN (while I know you did not have a NAT router when you posted last) side, I point to grc.com -> Services -> ShieldsUP! Then Press on Proceed -> GRC's Instant UPnP Exposure Test -> Then click on A sample “Exposed” result
. With an important note about that: Just because UPnP is disabled on the LAN side side (if it is) does not mean it is also disabled on the WAN side.
#9 Also if the NAT router offers wireless (or pure WAP), if and when you change your mind to enable it Be sure to:
a) disable WPS feature, as that has been hacked.Searching Google for about the wps flaw[/b]]http://www.google.com/search?hl=en&source=hp&biw=&bih=&q=wps+flaw&btnG=Google+Search&gbv=1]Searching Google for about the wps flaw[/b]
b) enable the highest wireless encryption that you can. For a home setting that is currently WPA2 Personal AES.
As why AES, I point to http://www.howtogeek.com/204697/wi-fi-security-should-you-use-wpa2-aes-wpa2-tkip-or-both/
