Client failure after firmware upgrade
Had a 3.19.3.0 client with the tunnel working fine.  Deleted the client config, rebooted (it was gone), Upgrade to 3.20.3.1, reinstalled tunnel client, reconfigured client and enabled, and rebooted.  Client does not connect to server anymore.  Server has been at 3.20.3.1 for a long time.

I have reconfigured the client, rebooted the client and the server multiple times.  I can telnet to the server through the internet router on port 5545 and get the tunnel version message.  I can't see anything wrong but the tunnel does not come up.  Need some ideas what to check next.

Client router config attached.

Hope it is just something stupid that I missed.

The tunnel was working right
The tunnel was working right up to the upgrade of the client and I can telnet to the server through the firewall.

Tunnel Upgrades
You don't need to delete (or disable) tunnel Client/Server tables when upgrading.  Simply remove the VTUN module before upgrading, reboot, upgrade Firmware, Reinstall Tunnel and you should be good to go with all previous settings intact.

Don't even need to remove the VTUN module.  You do need to disable tunnels, but the firmware update will delete the tunnel firmware for you (whether you wanted it to or not).

Disable Tunnel(s)
I find it easier to just remove the module.  Less actions if you have multiple Tunnel Clients and Tunnel Server connections.  Too many check boxes to undo and then re-enable!

That's what I thought but it is not working.
Does anyone know what modules I need to remove to be able to reinstall tunnel client?

Remove VTUN module
remove package vtun 3.0.3-2 from admin package management - remove package section.
Then reboot and proceed with firmware upgrade if needed.

Reload of tunnel client was no help
I deleted the tunnel package vtun and rebooted.  Reloaded tunnel client and reconfigured.  Rebooted.
Tunnel still does not come up.
