What version of frp are you using (./frpc -v or ./frps -v)?
frps: 0.21.0
frpc: 0.21.0

What operating system and processor architecture are you using (go env)?
arch linux

GOARCH="amd64"
GOBIN=""
GOCACHE="/home/sherlock/.cache/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/sherlock/go"
GOPROXY=""
GORACE=""
GOROOT="/usr/lib/go"
GOTMPDIR=""
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build834605009=/tmp/go-build -gno-record-gcc-switches"

Configures you used:
frpc

[home-ssh]
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 1026

frps

bind_port = 7000

dashboard_port = 7500
dashboard_user = holo
dashboard_pwd = VSH6928

how should I bind 127.0.0.1 on remote server, I only see remote_port not see remote_addr?
if not support, could you implement this feature, I think it is necessary only bind 127.0.0.1 on remote server like SSH or telnet for safe

Before the development team supports this feature, you can use iptables on the server where frps is located to disable external access except for 127.0.0.1.
