Yes, that would work.
Yes you can change the port. It is done in tasks.cfg:
[xymonproxy] ENVFILE /usr/lib64/xymon/server/etc/xymonserver.cfg CMD $XYMONHOME/bin/xymonproxy --server=127.0.0.1:1985,192.168.3.212 --listen=0.0.0.0:1984 --report=$MACHINE.xymonproxy --no-daemon --pidfile=$XYMONSERVERLOGS/xymonproxy.pid LOGFILE $XYMONSERVERLOGS/xymonproxy.log
You see here, I have the proxy listening on 1984, and it sends out to itself on port 1985 and also to another machine on the regular port, 1984.
You need to be careful where you send disable and acknowledgements. You want to send them to the servers directly not the proxies. If you send to the proxy, you will get a loop that will change the disable times seemingly randomly until the disable expires.

Hello,
Does this sort of architecture could work:
agent -> xymonproxy A -> xymonproxy B -> xymonserver
More, can we change the listening port of the proxy B ?
This could solve a security requirement in my company.
