Hi Chris,

I have some experience with this. A single host with dual-NICs needed to
act as a CA gateway server in two directions. In order to prevent the
ambiguity you suggest, it was necessary to explicitly lists the sources of
PVs (since there is no way to mask out an IP addr) for each CA gateway
process AND to make sure the CA gateway process ran as the correct IP
(that's the -sip arg or the EPICS_CAS_INTF_ADDR_LIST env var). Note that
wildcards wouldn't work in my case, since if I used them, I'd be including
the server and creating ambiguity.

HTH,
