Access to LAN while VPN client is running?

[Adam Funk]

Hi,

Until recently, whenever I've used my laptop on my home NAT LAN with a
VPN client running, I've had access to the LAN machines (e.g., ssh).
Recently, that stopped --- i.e., I can't ssh or http into any local
machines with the laptop VPN client running.  The only thing I can
think of that has changed is that I switched the router functions of
my cable modem off and installed a PepWave router.  But I can't find
anything in the router configuration related to this, and the LAN was
accessible with the cable modem as router and with the Linksys router
before that (which died).  Any suggestions?

(This is on Ubuntu-MATE 17.04.)

Thanks,
Adam
