So everything is going out of Sonic right now, right? That's what the
configuration and traffic graphs seem to indicate.

Looking at some traffic captures now, for mchawking's case, it seems that
it's not trying to route back through bikeshed. I bet its configuration was
setup to route back through the HA/floating IP (172.30.0.3), and bikeshed
did not get that configured.

I just added a static 172.30.0.3/22 configuration to eth1 on bikesked, but
it's still not working.

Jake -- could you unicast me a login to mchawking to debug what's broken on
there?

I mentioned that, as there was some other NAT mappings that were not moved
over for the mode S receiver, and data processing box for it.
