Listen on multiple RPC ports Running Ubuntu 17.10 server

bitcoin.conf contains a setting: rpcport=&lt;port&gt;

Is there any way to cause bitcoind (0.16) to listen on multiple RPC ports at the same time?

example: rpcport=1234,1235,1236

Currently, the wait-timeout prevents new connections to the RPC server until the old one times out. I want to avoid that by having clients use different ports.

If there is another (better) way to reduce/eliminate the wait-timeout, please advise.

Thank you.
Try and use iptables instead! Just forward the port secondary ports to the primary.
