(note -- The DHCP servers are enabled strictly for the wireless devices. All routers and desktops have static addresses.)
- Works: ping from LX00 (and any other 'L...' host) to HA01
- Works: ssh from LX00 (and any other 'L...' host) to HA01
- Works: http from LX00 (and any other 'L...' host) to HA01
- Fails: ping from HA01 to LX00 (or any other 'L...' host)

The ISP (Comcast) doesn't seem to provide a way to add routes on the "Cable Router Gateway" (or at least I haven't found it). I have complete (root/admin) control over everything else though.
There are numerous questions on Stack Exchange that are almost this scenario but either not quite or have unusable solutions for my case.
I've been working on this for several days, trying numerous routes, and have run out of ideas, so...
The Question...
What routes must I add to which devices in order to be able to ping/ssh --from-- HA01 to LX00, etc., and subsequently make HA01 a Synergy client?
