You can specify as many relays as you want in the config file. We have 6 specified, depending on where the endpoint is, it may only be able to talk to one of them. To specify more then 2 relays you can use the _BESClient_RelaySelect_TertiaryRelayList setting as well as setting a primary and backup relay. Here is what our Win config file looks like (I don’t think IP is necessary, but it works so I leave it there :
It takes a while for the relay selection process to fail over, so it can take an hour or so to get to relay 6.
It may also be possible to distribute the relay.dat file during the install (This is the file that holds all the available relays that is pulled when gathering) and let the clients do auto relay selection, but I haven’t tried it, the cfg file works fine in our situation.
