Thank you for your response. I already added to "me too" in the website.
I have added the host to Netview by the use of loadhost, but I do not 
understand why should I also need to touch the netmon.seed.
After doing the loadhost, the object inmediately appeared in the map and came 
green.

B. Regards
Alejandro Gabay

If your firewall blocks ping then that's your problem.  Your MLM will
merrily discover nodes on the same network as himself and will ship the
info to NetView in SNMP packets which should get through your firewall
on eithe TCP or UDP 161.  However, NetView doesn't believe what an MLM
tells him unless he can get at least one ping from NetView to the end
node.  If you find this behaviour perverse, please add a "me too" to my
enhancement request about this on
http://www.nv-l.org/twiki/bin/view/Netview/NetViewEnhancements#Enhancements_to_Mid_Level_Manage

Your best bet if you have 150 nodes out there is to construct a script
that uses the NetView loadhosts command to manually add them to the
NetView database and then configure those nodes in netmon.seed to be
SNMP-polled.

Effectively, MLM is a dead-duck for node discovery if it is behind a
ping-blocking firewall.

Cheers,
Jane
