[Xymon] Xymon client on private network - proxy solution?

Xymon users & admins,

I have a few servers(LDAP, QNAP/NFS, etc..) that are located on a private
network but can be reached via ssh by tunneling through various other
servers which are connected to the internet. I need to figure out how to
have these private network clients send xymon reports to my xymon server
located on the outside. I will try and map out the situation so you guys
can have a better visual idea with fictional IPs.

2 Main subnets are controlled by me
120.15.130.x
120.15.131.x

Server A : Main XYMON Server - 120.15.131.1
Server B : Current working Xymon Client - 120.15.131.2 & 192.168.1.2 (2nd
NIC connected to a switch which is not connected to any other outside
network)
Server C : NFS Server - 192.168.1.3 - I need an xymon client installed on
here and to be able to communicate(push reports) to the main xymon server
by going through Server B(proxy).

As you can see the NFS server is not accessible from the main two subnets
(120.15.130/131), only accessible from a server connected to the switch.
Connecting the xymon server to the private switch is not an option. Is
there anyway I can have Server B proxy the report from Server C to Server
A. Server B is already running tinyproxy, can I use this or do I have to
use a special xymonproxy extension? I would like to avoid having a 2nd full
xymon server, I would just like one of my current xymon clients to act as a
proxy or relay server.

Appreciate any help. Thanks,
*                                                            *
