Can not reach an internal device from outside the network

I have a Connect Box, with a computer attached to it using an ethernet cable. SSH server is enabled on this computer and I can connect to it, using its ipv6 address, with my laptop which is on connected to the same Connect Box (wirelessly, but that shouldn't matter)

 

I am trying to connect to this SSH server from outside my network, but that doesn't work.

 

Here is some potentilly useful information about my Connect Box:

Standard specification compliant : DOCSIS 3.0
Hardware version : 4.01
Software version : CH7465LG-NCIP-6.12.18.24-5p9-NOSH
IPv6 DS-Lite status : Enabled
DS-Lite-FQDN : aftr01.upc.ch

 

Under IP and port filtering, I have a table that looks like this:

Source IPv6 address Destination IPv6 address Protocol Source port Destination port Allow Enabled Delete
All 2a02:aa10:627f:a400:bfc:a2d2:ae51:1d30 / 128 TCP 1 : 65535 22  

 

That long string is the IPv6 address of my device.

 

When I try connecting to this from an outside computer, I see this:

 

connect to host 2a02:aa10:627f:a400:bfc:a2d2:ae51:1d30 port 22: Network is unreachable

 

What am I missing?

@msamani , welcome to our Community!

 

With IPv6, you cannot forward ports. That's why I changed your modem to IPv4. Now you can do the port forwarding in about 30 minutes in the menus and open port 22 from your PC to the outside.

Re: Can not reach an internal device from outside the network

Thank you very much. After rebooting the modem, I can see IPv4 port forwarding options, and I can access my machine from outside.
