 +For [[protocols#ftp|FTP protocol]] set of methods to connect over FTP proxies is supported. The methods differ by sequence of commands needed to instruct the proxy to connect to target host. The most typical method is //USER %user@%host//.

The original SOCKS4 protocol does not support proxy-side DNS. There is a protocol extension (SOCKS4A) which does support it, but not all SOCKS4 servers provide this extension. If you enable proxy DNS and your SOCKS4 server cannot deal with it, this might be why. The original SOCKS4 protocol does not support proxy-side DNS.

Connections to the local host (the host name ''localhost'', and any loopback IP address) are not proxied by default. It is very unlikely that this behavior would ever cause problems, but if it does you can change it by enabling //Consider proxying local host connections//.
