I would like to ask question regarding to forward-port rule for firewalld.
OS I am using is ,
CentOS Linux release 7.3.1611 (Core)
My Goal
Forward requests to httpd listening on 127.0.0.1:80
[root@development /]# netstat -atunp | grep httpd
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 2601/httpd
Problem
I have set firewalld rule as below.
[root@development /]# firewall-cmd --list-all --zone=external
external (active)
target: default
icmp-block-inversion: no
interfaces: eth0
sources:
services: ssh
ports:
protocols:
masquerade: yes
forward-ports:
sourceports:
icmp-blocks:
rich rules:
rule family="ipv4" forward-port port="8080" protocol="tcp" to-port="80"
However, if I send request from external host, firewalld rejects request to port 8080.
In this case,
192.168.11.2 (client) -------> 192.168.11.13 (8080)
[root@dellinspiron13z asset]# curl -XGET 192.168.11.13:8080
curl: (7) Failed to connect to 192.168.11.13 port 8080: Connection refused
If the process is running as 0.0.0.0:80 , it works perfectly.
Is there anyway to redirect requests to localhost port?

You have to change route_localnet in sysctl on interface with address 92.168.11.13 or for 'all' if you lazy
In lucky coincidence I have fresh CentOS with same version, so by default this knob is disabled
[root@tesla ~]# cat /etc/centos-release
CentOS Linux release 7.3.1611 (Core)
[root@tesla ~]# sysctl -a | grep route_localnet
net.ipv4.conf.all.route_localnet = 0
net.ipv4.conf.default.route_localnet = 0
net.ipv4.conf.enp0s5.route_localnet = 0
net.ipv4.conf.lo.route_localnet = 0
