Hi all:
I am trying to setup a cluster of 5 Redhat 6.1 boxes. I am in the initial
stages of the setup. I have setup one active router and a real server
talking to it. The real server is in the local subnet (IP
address is 192.168.1.6). I am able to ping the active router from the real
server and vice versa. I have enabled packet forwarding and packet
defragmenting on the active router. I've issued the following command to
masquerade the private network.
ipchains -A forward -j MASQ -s 192.168.1.0/24 -d 0.0.0.0
The problem is that I am not able to ping the public LAN from the real
server.
The active router has the following config:
eth0 Link encap:Ethernet HWaddr 00:00:C0:9E:5B:94

Please help me in identifying the problem due to which the network
connection between the real server and the public network is not getting
established.
Thanks & Regards,
Hitesh.
