Cannot access my own game servers

[Snotrap]

Hey all!

 

 

I think I have somehow blocked one of my machines from my gaming pc.

 

I cannot access anything off of it, not an apache server, shared files, game servers of mine etc.

 

I have port forwarded the ports etc, also set DMZ to the machine.

 

My main pc LAN IP is something like 192.168.0.7

And the server is 192.168.0.17. 192.168.0.17 is set to DMZ and ports are forwarded etc.

 

My host file looks like so on my gaming pc:

 

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1 localhost
#    ::1 localhost
 

 

Any help is greatly appreciated!

just fyi i am fairly certain that a hosts file is what BLOCKS ips, addresses as well. You will want to make sure that file sharing is on and your server is accessible over the network, allowing ip access, file management, etc.

What OS is your server running?

Did you make any changes before it stopped working?

Can you ping the server from your host? Can the server ping your host?

[schizznick]

If you are using the external IP or domain to access it, then your router will need to have NAT loopback capability. Otherwise you won't be able to hit that external IP.

So theyre in the same subnet so its just basic switching. 

Can you ping from 1 machine to the other? 

 

P.S putting it in DMZ is pointless if its just internal connection - you should remove it from DMZ for security.

Does DNS break it?

dns shouldn't break it unless you are using a local dns server to have private domains to access your server.

try changing it back to what you had before just to check

Try ping (and RDP) it by its IP address and take DNS out of the equation. 

When you have a complex problem, you're first best to simplify if its a network or a service issue.

Can't ping it afterwards or anything

not even by IP? 

maybe theres a problem with your ARP cache / table. 

 

assuming your ip is static and that 192.168.0.17 is the IP of the server?

you may have to try clearing your ARP on your machine and/or rebooting your router
