&gt; Have a orbi 6 rbk753 ax4200&nbsp;&nbsp;&nbsp; Connected to what?&nbsp;&gt; [...] Need to open ports 80,5000,9000,18004 [...]&nbsp;&nbsp;&nbsp; Says who?&nbsp; For outgoing connections (no action needed), or forincoming connections (unlikely, port forwarding might be needed).&nbsp;&gt; [...] Told ip is private needs be public&nbsp;&nbsp;&nbsp; With my weak psychic powers, I can't see it from here.&nbsp; Point a webbrowser at the management web site of your router, and report what youfind at: ADVANCED &gt; ADVANCED Home : Internet Port : Internet IP Address.Plug that address into the form at: https://whois.arin.net/ , and see ifit is a public or private address.&nbsp;&nbsp; The usual cause for that to be a private address would be connectingthe RBK753 router to some other router -- either a device on yourpremises, or one at your (unspecified) ISP, if they use carrier-gradeNAT.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; https://en.wikipedia.org/wiki/Carrier-grade_NAT

&gt; rbk is conected to a spectrum modem&nbsp;&nbsp;&nbsp; Thanks for the details.&nbsp; So, if I plug "a spectrum modem" into mysearch engine, I'll get all the information about _your_ modem?&nbsp;&gt; [...] told me possibly the ip adress 172. is private and not public a&gt; class B .&nbsp;&nbsp;&nbsp; From "172.", I can't tell.&nbsp;&gt; Plug that address into the form at: https://whois.arin.net/ , and see if&gt; it is a public or private address.&nbsp;&nbsp;&nbsp; You can see that address, and I can't.&nbsp; Which of us, do you think,should try that experiment?&nbsp;&gt; [...] or one at your (unspecified) ISP, if they use carrier-grade NAT.&gt;&gt; &nbsp; &nbsp; &nbsp; https://en.wikipedia.org/wiki/Carrier-grade_NAT&nbsp;&nbsp;&nbsp; Ask your ISP?

&gt; They told me the 172. Ip is one created by my net gear router it not&gt; there's&nbsp;&nbsp;&nbsp; Ok.&nbsp; And if I could see what it actually is, then perhaps I couldtell you something, too.&nbsp;&gt; Can the ip be changed in my router ?&nbsp;&nbsp;&nbsp; Sure.&nbsp; _Which_ IP address would you like to change?&nbsp;&nbsp;&nbsp; Please review this thread, and look for "?".&nbsp; Those are questions.If you answer them, then perhaps we could make some progress.&nbsp; If youcan't/won't answer them, then I have better ways to waste my time.
