Hello

I am trying to setup a nework using IP Masquerading. I followed the instructions/ steps as follows:

1. Appropriated a multi-homed box
2. I have installed Redhat Linux 8.0 on it (base install)
3. INetwork settings
eth0 192.168.0.1 netmask 255.255.255.0
eth1 a static IP my ISP had provided. netmask 255.255.255.248 gateway: the one provided by my ISP.
4. ran the following commands
# route add -net 192.168.0.1eth0
192.168.0.1eth0: hostname not found
# route add -net <my.static.address>eth1
<my.static.address>eth1: hostname not found
# route add default gw <my isp's gateway IP>
# ipfwadm -F -m -a accept 192.168.0.0/16 -D 0.0.0.0/0
-bash: ipfwadm: command not found
5. I restarted the network
6. On my client (Windows 98), I configured the TCP/IP setting as IP: 192.168.0.2/ 255.255.255.0/ netamask: 192.168.0.1/ DNS Search order: provided my my ISP

The problem is... I am able to ping both the 192 address and the externel IP address of the host (the box on which I have the IP Masquerading setup). I am also able to browse the network - within the same WORKGROUP. I am however not able to browse the external internet! I have setup my browser proxy setting to the IP of the host (eth0) on port 3128.

Am I missing something? Please Advise!

Thanks

Your gateway should be resolveable in the /etc/hosts-file
Also /etc/nsswitch.conf should point to :

hosts files .......

Regs David

I have checked both the files...
1. I have included
192.168.0.1 CESSNA
2. The /etc/nsswitch.conf already has an entry reading:
hosts files nisplus dns

This did not help! Any other ideas?

Thanks

It doesn't look like you have ipfwadm installed. Try iptables (www.netfilter.org). Is ip_forward turned on? What is the output you get when you do 'ifconfig -a'? Your Linux box should be the gateway for your Windows client.

You may not have a nameserver ( DNS )

In your /etc/resolv.conf put the following

domain www.yourdomain.com

nameserver 10.0.0.1
nameserver 10.0.0.2
