Subject: Beacon like connection attempts from caGateway

Hi all

I am setting up a cagateway system to allow for PV access to our lab net from the general "office net".

The gateway process is run as:

cagateway -cip cagw -cport 5066  -sport 5064 -log epica_gateway.log -archive -no_cache -server -ro

Connecting to the host cagw on port 5066 providing access  to the PV's seen there
(this is also a cagateway instance running with -sport 5066)

This all works nicely, and as I understand it is ok to live without access to the beacon signals on the outer office net.

However, my problem is that the network people does not like that the
cagateway process tries to connect back to the cagw host on port 5065/udp

I do not understand this behaviour.
* It is a very regular pattern with connection attempts every 15 second.
* I do not understand why the cagateway process "client side" would try to make direct connections to the 5065 port
    on the "server".

Can anyone explain?

Best

    Bo
