What I wish for CA server is that NIC2 does not "receive UDP search
messages and or connect TCP circuits destined for NIC1 of the IOC and
other interfaces". This seems to match with the capabilities you
described.

You can arrange that with the existing software as long as you put NIC2 on a different subnet than NIC1. If both interfaces have addresses in the same IP subnet, no server application can control which interface will get used for the TCP socket connection. This is a limitation of the TCP/IP networking kernel, not of the EPICS CA server software, so don't wait for Jeff to try and fix it because I don't believe he can.
