Can't access my home network from outside

cagribaba — Sat, 24 Sep 2022 09:47:37 GMT

1. I set up Dynamic DNS service(NoIP) in router interface

2. I made proper port forwarding, lets say 1234

3. I can not ping my computer from outside internet

4. I can not access HTTP server from outside internet either

I think FritzBox needs more than just port forwarding to allow access from outside network. Do I need to disable some hidden firewall somewhere?

Any help is appreciated.

is this a rented Fritzbox or your own?

in which federal state of Germany do you live?

which contract do you have?

Your problem most likely is that you try to access your network using IPv4 - this is NOT possible using the (contractually agreed upon) DualStack-Lite protocol. You can only access your network using IPv6 addresses, not through IPv4!

It is Fritzbox from Vodafone, not my own.

So, technically, if I know my IPv6 address, I can connect from outside without any interference from router? Of course I think I need to make some changes through router to activate IPv6.

you need to configure an "IPv6 Freigabe" on the Fritzbox for the device you want to reach from outside

IPv6 is already active on ds lite connections

And you need to use the IPv6 address from the device itself - NOT from the router!

I checked IPv6 Activation under FritzBox interface and it is disabled under Internet -> Type of Connections. There are only AVM Services and DNS Server tabs.

I asked Tobi(vodafone automated assistant) about how to do public IP settings but it says only business customers from Frankfurt can have public IP address. Am I understanding wrong? Is there no way for me to get public IP and accessibility from outside internet because of my location?

Note: I checked my IPv6 address with https://test-ipv6.com/ and ipconfig command on Windows under Ethernet -> Temporary IPv6 address. Both say the same IPv6. But I can not ping this IPv6 address from the outside world.

I also do not know what ports I need to share in Fritzbox interface for ping.

configure an IPv6 release for your device and allow PING6

I appreciate the help. But I couldn't find any place in FritzBox UI to configure ipV6 or allowing Ping6. On which pages in FritzBox interface can I do these?

Note: I was able allow Ping6 from Internet -> Permit Access -> Port Sharing -> Sharing For Device -> IPv6 Settings tab.

I was also able to get global IPv6 address, by ifconfig

XXXX.... prefixlen 64 scopeid 0x0<global>

But I also get the result below;
ping6 ipv6.google.com
ping6: connect: Network is unreachable

How is it possible that I get global IPv6 address but I can not ping IPv6. I have activated IPv6 settings in FritzBox 6660 interface too.
