Hi,
For demo purpose we set two lans as following series of ip
192.168.10.* and 192.168.2.* and in the router machine eth0 is 192.168.10.102 and eth1 is 192.168.2.102.. when I try to using nmap from router it will find the 192.168.2.* but its unable to find the hosts in 192.168.10.* i tried the -e option nmap -e eth0 192.168.10.* but it is not detecting.. help plz..
Thanx in advance,
Regards,
lok.

Do you even have connectivity between the router ?
Can you ping from both networks boxes on other networks ?

If so , try the -P0 (<-- P null) option, this forces it nor to rely on ping to see if a host is up or not .

Take the search function and search this site for tutorials on nmap by thehorse13.

The normal -sT mode pings to see if a host is up. But most firewalls can drop icmp echo request, making it fail your nmap. But read those tutorials and you'll learn more .
