I'm using a SOCKS5 proxy for bandwidth throttling and custom latency. How do I run bitcoind such that only node connections go through the proxy, but JSON-RPC does not? The proxy is on localhost, and 2 nodes are running in seperate data directories with ports also on localhost. No Internet connections are needed. My OS is Arch Linux 5.2.1 running on a virtual machine, x86_64, and my bitcoind version is 0.18.0.0.
