Is your tunnel using PSK? How many characters are there?

Yes PSK with 21 characters

Is it possible to “shrink” to 18 char for test?
I had similar issue here…

(I could probably be wrong… but i hope it’s worth the test…)

Unfortunately the other firewall is a zywall managed by another company at € 70 per call.

I have already installed a Nethserver Appliance (only for vpn in bridge connections), i’m waiting to move all the services on the NS and I will use the new VPN module.

thanks @pike I did not see the post, in fact until a few days ago it worked perfectly

But sorry, the log says clearly that you do not expect it
Unexpected STRING [Protocol]

It can simply be the uppercase letter?

During the weekend ad updated IPsec package was released, adding among other things to enable/disable tunnels from the tunnel list.
I also added a reboot for my issues…

Hi @sharpec it is a regression caused by nethserver-openvpn-1.6.0-1.ns7.noarch release.

A migrate fragment from that package pollutes the vpn DB.

I’m fast-tracking this issue, do you want to test the fix?

BTW: great catch!

of course

The fix is available from nethserver-testing repo.

Please install with

yum --enablerepo=nethserver-testing update nethserver-openvpn

The vpn DB contents should be fixed after installation. Restart ipsec manually with

 signal-event nethserver-ipsec-tunnels-update

Check the exit code is 0:

echo $?

Released

nethserver-openvpn-1.6.2-1.ns7.noarch.rpm
