Route Table help please
Need a bit of help with routing tables, I am trying to resolve spoofing problems within MS TMG and I am having a few problems configuring the routing tables to stop it ( i am new to routing tables).
I understand the theory behind the routing tables but what I am struggling to get is what exactly to enter in.
MY network runs as follows:
10.217.x.x with a mask of 255.255.0.0 we use various ip sets like 10.217.10.x - 10.217.14.x for DHCP and other ranges for printer etc.
How do I cover adding all these ranges to stop the spoofing,
I have tried route -p add 10.217.0.0 255.255.0.0 10.217.0.110(the nic) but it does not seemed to have stopped it, what have I missed.
Any nudge in the right direction would be much appreciated.
Are you sure this is actually fix-able with routing tables?
It should be fixable, how many devices are spoofing on your network?
Did you miss the mask bit out of the command or just when you wrote in here?

The server is in a test UO at the moment with only 1 user PC, I get random machines as spoofed, I have added a new persistant route (I did forget to put mask in :) ), I have cleared all alerts and see what happens.
