[thelist] [OT] networking W2k & Red Hat 7.2

[Judah McAuley]

The first thing to make sure of is that each machine has the right basic 
network settings.

The RH box should have 2 ip addresses.  One "real" address will be supplied 
by the ISP.  This address needs to be bound to the ISDN card.  To make sure 
that this works, log onto the RH box and make sure that you can ping things 
in the outside world, like www.evolt.org

If you can't ping something from the RH box, then you external settings are 
messed up and you need to start there.

If you can ping the outside world, then you need to make sure that the 
internal network settings are correct.  Most people use the range 
192.168.0.1 - 192.168.0.254 for their internal networks.  You need to pick 
an address in that range to be your "gateway" and bind that to the RH box's 
ethernet card.  Most people use either the .1 address or the .254 
address.  Most people will use 255.255.255.0 as their netmask.

Moving over to the Win box, the ethernet card should be using an address in 
the internal range (like 192.168.0.2) with a netmask of 255.255.255.0 and a 
gateway value set to whatever internal address you assigned to the RH 
ethernet card (192.168.0.1 or 192.168.0.254).  One of the most common 
mistakes is to set the Win boxes address to the external ip address of the 
RH box (the "real" ip address).  This won't work and will cause a lot of 
frustration.

This setup should work.  If it doesn't, then you are probably dealing with 
configuration issues inside the firewall software.  At least you'll have 
narrowed down where the problem is.

Hope this helps,
Judah
