Archer VR600 v2 + Forticlient VPN = no internet access over wifi link
I recently bought an Archer VR600 (v2) with the following specs:
Hardware Version:Archer VR600 v2 00000000
Firmware Version:0.2.0 0.9.1 v0074.0 Build 170504 Rel.68210n
From work, we are now forced to use FortiClient free software for VPN access to work computers.
When I dial up the VPN via a wired connection (e.g. my desktop PC), all works fine.
However, when I dial up the VPN via a wifi connection (e.g. on my laptop), internet connection STILL works (I can check that the DSL link is alive and kicking from inside the modem admin panel) but the laptop shows an internet disconnection at the task tray. And indeed no up or down traffic ensues.
a) Over my mobile phone's 4G connection the laptop + forticlient works fine. So, it's not my laptop's wifi the problem.
b) All proper Firewall and NAT settings are by default enabled, e.g. L2TP passthrough, IPSec passthrough, etc. (but I don't see any SSL or VPN passthrough?)
But it clear to me that when on a wifi link, VPN traffic is shunted from my laptop.
Can you please advise how can I solve this? It feels to me like a firmware bug related to the wifi settings of the modem. (e.g. Could it be that VPN port forwarding does not happen successfully when connecting via a wifi device to the modem?)
