[Help] Server is online but only others can connect and host pc

Hello, at my shop i own 70 pc's.
1 pc hosting a mu server and the others trying to connect.
I have all the ips configured and the ports open, other people can connect and the host pc can aswell(only with microsoft loopback adapter)
The other comptuers at my shop can not connect what so ever.
help?

O yes, I'm using a modem

no router?

I think they are the same, well atleast i can do the same thing.
Same thing when i was back at home, only the host pc can connect and people outside of my network can connect aswell
it's very weird
edit:
modem+hub

Ok i get now, what you want to say. The Network/LAN PCs cant connect to the Server.

To connect from LAN you need to edit your host

go to C:\WINDOWS\system32\drivers\etc

then edit the host (open it in notepad)

put your LAN IP then your WAN IP below the 127.0.0.1 localhost

heres the sample

Code:

# 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

127.0.0.1      localhost
192.168.2.156        WAN IP

you need to edit the host in your server's pc and your client's pc

make sure the LAN IP you use is your server's LAN IP

hope it works for you :wink:
