Bob - thanks for your reply!

Yes… that is exactly my first thought too, but alas 'cat /proc/sys/net/ipv4/ip_forward' yields a ‘1’, so no joy yet.  

Here’s my linux routing table with jnos running:

pi at raspberrypi1:~ $ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.0.1     0.0.0.0         UG    202    0        0 eth0
192.168.0.0     *               255.255.255.0   U     202    0        0 eth0
192.168.0.149   *               255.255.255.255 UH    0      0        0 tun0
pi at raspberrypi1:~ $ 

So my tunnel is .148 and .149 — 149 .  148 is the linux side and 149 is the jnos side and in the DMZ. Does anything stand out from this?

Best,
jerome

I then made a new SD card using the most recent noobs, and then sftp’d the tarred jnos into a jnos directory on the new card. Jnos comes up with no errors, however, I no longer can ping the router from inside jnos — and thus jnos can’t see the net.
