internet cable port sharing issue

[Mantaray]

Hi Guys , I insttaled kabel internet fewsays ago with fritzbox 6600. I did all required ways to open port 44158 in TCP protocol with IPV4 but all time I see that port still close or the settings I do opening another port .

-- I reserved the local IPV4 to my device then to "pirmit access" to make port sharing as shown in totorials but what I see that port 44158 still closed and port 58024 is open.

any idea how to solve the problem?

There is no solution to this problem as there is no problem at all.

You opted for a contract that uses DualStack-Lite operation - and as it is written in the contract details, you don't have a public IPv4 and thus IPv4 port forwarding is not possible.

Hi, thanks for reply,

Before I do my contract sales team confirmed that I have a real static IPV4 address and they told that I can do port sharing. my contract is red internet and phone 250 cable with fritzbox 6600 router

Whatever you were told - private contracts are only being served using DualStack-Lite technology with no public IPv4 address at all.

Only Business contracts include an option to get a (public) static IPv4 address -- but your contract misses the "Business" in its name, so it's only a private contract and therefor does not have a public IPv4 address at all.

got you. but how when I check my public IPV4 address its the same and never changes even with restarting router? is that doesn't mean that I have a static IPV4?

Thanks again for your time

You don't have a public IPv4 address at all.

The IPv4 address that you see if your check on different websites is the one that the NAT Gateway from Vodafone uses - and that is an IPv4 address that you share with many other customers.

just wanted to add my feedback about that issuw minsioned qbove, after a phone call with technical suppport they offered me a free real static IPV4 address and from the router settings I shared the port 44158 and now it's open successfully
