With OpenVPN? I'd disagree. If it's the case with OpenVPN, than it 
usually means that someone misconfigured OpenVPN server.

It wouldn't normally act as a gateway without:

# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the VPN, causing
# all IP traffic such as web browsing and
# and DNS lookups to go through the VPN
# (The OpenVPN server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
;push "redirect-gateway def1 bypass-dhcp"

Hi Tomasz,

what you quote doesn't say anything about whether the server would 
actually forward traffic for the default-route.

It says, that clients are encouraged to configure the default-route
via the VPN gateway. Depending on how you configure openvpn client-
side, it may follow the server's suggestion (--pull, ipv4.never-

Whether server-side would route traffic to a certain destination
depends on the server's routes, iptable rules, ip_forward, and openvpn

But there is no real disagreement here. A ~server-choice~ option
certainly would make sense. I merely said, that I don't agree with
"would almost never work".
