Re: [nv-l] PC becomes Router !!

I believe if you use regedit and navigate
to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

look for the value for IPEnableRouter;
 1 means IP Forwarding is enabled;  if you issue the following,
you can also see it:

snmpget <hostname> ip.ipForwarding.0



I have set this on before on machines
with more than one nic card, but have not seen it get set by itself.

Yes, it is normal. It usually means the ipforwarding is enabled between
the interfaces on the server. If you do not want to see it at that level
of the map, your best bet is to hide it from that submap. It will still
show up in the segments on which it has interfaces.

Subject	[nv-l] PC becomes Router !!

Hi all,

my Netview is 7.1.3.

On my network, a PC (W2K SP4) had one network interface in 
192.168.80.x/24 and all was fine (trap well received, etc ..)
Then I added on this PC a second network interface in 169.254.x.x/16. 
After a manual polling request, the second interface was discovered, and
the object was added at the network level (in root submap), linked to 
the 2 IP network  (192.168.80.x/24 and 169.254.x.x/16) and in its
properties : IPRouter, Node, Computer, Connector, Router, PC, IP.
Before the add of the interface, the properties was :  Node, Computer,
Connector, PC, IP.
Note the icone used to display the PC is still the PC icone.

Is it a normal behavior, I mean when a host have 2 interfaces on 2 IP 
networks, it is considered as a router ?

thanks for your help.
