Hi,
I've having some trouble creating a Shorewall configuration that will
provide an LXC container connectivity through its host machine. To be
more precise, the host machine currently has full connectivity to the
LAN - both in and out - via ssh, ping, wget etc. The container, on the
other hand, can only ping/ssh to/from its host (and gateway). I'd like
ssh etc., access into the container from anywhere on the LAN.
Without Shorewall running, the container has full access to Internet
resources (wget, curl) but, of course, no way in except through the host.
I would really appreciate it if anyone can help!
Thanks so much,
David
Here's my config:

The shorewall.conf file is, to the best of my memory, in pristine,
default condition.
