Hi all,
We're installing a Linux server to be a Internet
gateway/firewall and replace a Windows NT/Proxy Server
in our computer lab. The setup is as follows:
Livingstone
Portmaster --- > Internet
|
|
--------------------------- 200.250.x.x network
| connected to the Internet
|
Linux server (Redhat 6.2, kernel 2.2.12-20)
| with 2 nics
|
--------------------------- 192.168.1.x network
| | | internal network
| | |
Windows 95/98 clients
The problem is that the Windows clients are not being
able to use any ip service (like web, telnet, ftp
...). We've followed the instructions in the
ip-masquerading faq and other sources, and used the
following commands to enable it:
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -s 192.168.1.0/24 -j MASQ
However, the ping command does work to reach any
Internet address from the Windows hosts. There's also
a strange detail: the traceroute output from the
Windows clients shows no response from the Portmaster.
I think this has something to do with the problem but
I didn't get the relation.
Does anybody have an idea on what could be the problem
? We're really stuck here.
Thanks in advance,
Marcos C.O.Pinto
