Routing question!!

[Mark A. Tagliaferro]

I have the following system where I'm using Suse 7.1 on the servers:

               172.22.2.0/24   172.22.3.0/24   172.22.4.0/24
                   Clients         Clients         Clients
   Internet         Win95           Win95           Win95
      |               |               |               |
+----------+    +----------+    +----------+    +----------+    
|   Srv1   |    |   Srv2   |    |   Srv3   |	|   srv4   |
+----------+    +----------+    +----------+    +----------+
      |               |               |               |
      +---------------+---------------+---------------+
          backbone network  172.22.1.0/24

On srv1 I have masquerading, NAT,  firewall etc running and it's working well.
