large in the tinc-up script.  After making that correction I am now able to
get to the IP of the tunnel interface (which is the same as the IP on the
eth0 interface).  I can also get to other IPs in the same subnet by setting
a route on them to use the tinc "server" as the gateway.

However, I am not able to get to any other subnets by adding additional
subnets.  Do all subnets that I wish to access need to fall within the same
subnet as is defined in my tinc-up script?  The problem is that I have some
10.x.x.x addresses and some 192.168.x.x addresses that I would like to be
able to access.

Also, I am not always going to have the clients using the same IP space on
their eth0 interface, which was why I originally defined a separate subnet
specifically to be used on the tun0 interface.  I have some clients with
10.x.x.x addresses on eth0 and some with 192.168.x.x on eth0.
 Unfortunately, even after adding those subnets to the host files as you
mentioned, I still cannot get it to work unless I use switch mode.  Is this
a limitation of how tinc works, or am I possibly still doing something
wrong?

Thanks for your help,
Ryan
