HI all,
I have setup IPTables firewall/Router and my home network, with address space 192.168.10.XXX
Form my private network hosts, i can ping the gateway ( 192.168.10.101 ) , but the reverse is not happening.
Can someone help me as of what i need to do, so that i can ping my private hosts form the gateway.
........................................................................................................................................
Also some additional details about my network.
I have a 2 MBps adsl connection form an ISP.
and have two cards in my gateway, One card ( eth1 ) connected to adsl router, and second card ( eth0 ) connected to my private network ( a d-link unmanaged 8 port switch )
