Hi there list I have the following issue:

I have a IP split setup on one of my Linux boxes (see diagram below), I can route and all access is hunky dory,... BUT I want to block access to my DMZ'z gateway address from the outside world.
   How do I do this?

|            |       eth0 +-------------+  eth1      |             |
|  Internet  |============| FW / Router |============| LAN         |
|            |            +-------------+            |             |
+------------+                    || eth2            +------------ +
                                 ||
                                 ||
                                 ||
                                 ||                 +------------ +
                                 |+-----------------|             |
                                 +------------------|    DMZ      |
                                                    |             |
                                                    +------------ +

KEY:
~~~~
eth0   =>   196.x.x.122 / 255.255.255.252
eth1   =>   192.168.x.x / 255.255.255.0
eth2   =>   196.x.x.94  / 255.255.255.240


The Internet needs to be able to see 196.x.x.80 -> 196.x.x.95,... with the exception of 196.x.x.94!!!

Everything else is correct and how I need it to be,... I need to know how to DROP the packets coming in on eth0 for 196.x.x.94
BUT packets coming in on eth2 for 196.x.x.94 need to be allowed.

Regards,...
