In my LAN network I have a server with Scientific Linux (RedHat or Fedora based distro), I've done
yum install nginx but the welcome page is not accessible from other computers in my network.
When I do
telnet open localhost 80 and then
GET / HTTP/1.0 I get some html code from nginx, so it's running for sure. But when I want to connect remotly, doing
telnet open 192.168.3.130 80 I get:
Trying 192.168.3.130... telnet: Unable to connect to remote host: No route to host
So I assume that there is something wrong with my network settings, maybe iptables or something else?
Next step, I turned off iptables:
service iptables stop and it helped, now I can connect remotely using telnet.
So I think, I need to fix my iptables rules. I did some googling and found this rule
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT but it still didn't allow me to connect remotely when iptables is up.
Can someone please help me setting a proper iptables configuration?
