Openvpn, can ping network but nothing else

Hi all

I am running into a weird issue with my openvpn setup.
I have a tcp server running on my openwrt edge router, and some clients, and android and a pc one.
The pc client run in an openwrt istance as well.

It was working untill some time ago, I made some modification in my edge router.

Currently I have the android client that works ok, while the pc one can ping all the device in the openvpn server network, can ping also website, but cannot do anything else, like ssh into network device or make traffic via squid

This is a tcpdump of a ssh attempo from client ( to the openwrt server where openvpn server run (

On the PC openwrt client there is also squid server running, that cannot make any traffic trough as well.

On the openvpn server I did not change anything, and as said the android client works ok... So I am very lost here!

Thanks for the support

Hi, solved

I had to update openvpn from 2.4.0 to 2.5.0 that is the same of the server
Very, very strange, I did not read of such problem before
