Pine64 OpenVPN Server - Client connections not works from any place

[ricciolino]

Hi all,

I describe my current scenario.
I set up a Pine64 single board computer as OpenVPN server for my home network (ArmBian OS). For this scope I used a similar version of the famous pivpn-install.sh script that can be found around GitHub repos.
Everything works as expected with just one exception.
I am able to connect remotely to my home network from my Android device using the official OpenVPN client (mobile data ISP).
I am able to connect remotely to my home network from my Dell Laptop dual booted from Windows 10 OS using the official OpenVPN client.
I am able to connect remotely to my home network from my Dell Laptop dual booted from Ubuntu 22.04 OS using the official DEB OpenVPN package (

Code: Select all

sudo openvpn --config client.ovpn

) when the Dell PC is connected though hotspot connection to my smartphone.
But.... I am not able to do the same last thing, from my Ubuntu 22.04, when the PC is connected to another home network, pretty standard home network of a friend of mine, having a subscription with the same ISP provider company.
I mean, what happens is that the log messages printed after

Code: Select all

sudo openvpn --config client.ovpn

arrives to the "Initialized sequence completed" , and everything seems to works fine, indeed the OpenVPN show me that a client user is connected to my home network, but I am unable to ping other hosts connected to my home network.

I am wondering which could be the reason for this unexpected behaviour.

I am not very expert in this field, so please, ask me what you need to clarify the situation or tell me practically what I have to do to solve this unexpected issue.

Thanks in advance for your help.

I actually solve it by checking at this post (viewtopic.php?t=19762).
I changed the IP class of my home router from 192.168.1.1 to 192.168.0.1 .
