Hi,
Any idea about remotely discover & monitor all IPs, hosts & devices attached to all subnets that connected to Billion (BIPAC 5102) router which has single Static WAN IP & configuerd to DHCP & NAT on the LAN side, please? or I Should change the Billion with other router kind?!
Note: all Devices on the LAN side should not have static IPs.

You could write a linux script yourself (some perl and Bash should do you well), or you could just go out and look at www.solarwinds.com.
They have a demo of their network engineers toolkit. It has a utility called network sweep. You give it the networks you want to scan and it will enumerate all hosts on that net, then using SNMP or DNS it will resolve them to a name. You can then export the list and import it back into the monitoring app of Solarwinds and you're done.

Dear superjn@
Thanks for reply
I'm already using Network Engineer's Edition Toolset (Version 8) and there is no utility called network sweep, I don't know if you mean the SNMP Sweep tool, but it dosn't help.
Also when I try WhatsUp Gold software it just discover the remote router only and continue discovering the devices & workstations of the local subnets not those on the remote site!

I apologize for the incorrect naming of the utility. Look under network discovery, and select IP network Browser. Enter your network range and you should be able to enumerate the entire network.

Dear superjn@
Thank you again
I think I didn?t explain the situation well.
1) The network I need to discover is not the local network, but it is on the other company branch and I?m connecting to it through an internet via DSL.

2) This target network is connected to the internet through the Billion (BIPAC 5102) router router via DSL & has single WAN static IP (196.205.xxx.xxx) , the Billion router is the gateway which has the LAN IP (192.168.1.254) and acting as DHCP so it gives the LAN attached to it the IP range from (192.168.1.100) to (192.168.1.200) dynamically.

3) When I use the IP network Browser and gives it the WAN static IP (196.205.xxx.xxx) it finds the router, and the subnet attached to it only, and gives no info about workstations, also no IPs or MAC, and in the TCP connections node it reports all connections IPs as (192.0.0.0) source and destinations as (xxx.0.0.0), but it gives correct port number for each connection.

I hope I had explained it clearly.
