Hi Dan,

Tunnel All is what is preventing you from accessing the Internet and
your Local LAN.  

Unfortunately, you may not have a choice to not tunnel all, as it
depends on what your customer's gateway is expecting.  If the gateway
is expecting you to connect with a remote network of 0.0.0.0/0.0.0.0
(which is tunnel all), then it will not let you connect with something
different.  Since you can connect successfully, I would suggest that
this is in fact what the customer's gateway is configured for.

To maintain local lan access while connected, you can change your Shrew
config.  Unselect Tunnel All, then add:

exclude 150.237.13.0/255.255.255.0
include 0.0.0.0/0.0.0.0

I don't know a workaround for the loss of internet access, that's an
effect of routing everything to the customer's network.
