Hi,
                My network guys are building a couple new networks that for security reasons won't be directly connected to our xymon servers.

                There are two machines that are just 1 network away, and the firewall allows them through. And then there are 2 networks that connects to the customers that has 1 server on it each. They talk to the first 2 servers.

                So my question is, do I have to put a xymon proxy on the first two machines, or could I do something weird like bring up msgcache on it, and then have the far remote machines send to the message cache?

I'm doing this on a remote network. See my note to the list of 20141226 
for the long version.
http://lists.xymon.com/pipermail/xymon/2014-December/040853.html

The short version is:
  Run msgcache on a system
  Clients near that system can report to it
  Use PULLDATA on a remote system to retrieve from the cache

Watch out for:
  Port not performing as specified (1984 only)
  Passing data unencrypted across the network links
  All message types are passed

I see that in my note of 2014, I left an un-answered question:
I don't know how many (or how quickly) messages can be cached by
msgcache. It was designed to accept messages from an isolated client. It
is possible that it will not be able to keep up with an influx of
messages from xymonnet.
I still can't say how many messages it can handle, but I can say that 
for the last year it has handled the xymonnet results for 30 hosts 
without incident or complaint.
