IP Masquerading
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

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
