I'm running RedHat5.0 on a box with 2 ethernet cards. One is connected
to a "private" network (IP address 192.168.1.1) and the other is
connected to our departmental network (IP address xx.yy.zz.142). Both
work quite happily and both networks are accessible from the
machine.

Our problem is that we can see 192.168.1.1 from the departmental
network.

The configs and routing are setup thus:-

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:287 errors:0 dropped:0 overruns:0
          TX packets:287 errors:0 dropped:0 overruns:0

eth0      Link encap:Ethernet  HWaddr 
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:67830 errors:12 dropped:12 overruns:0
          TX packets:35811 errors:0 dropped:0 overruns:0
          Interrupt:9 Base address:0xef00 

eth1      Link encap:Ethernet  HWaddr 
          inet addr: xx.yy.zz.142  Bcast: xx.yy.zz.255  Mask:255.255.254.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:6159956 errors:0 dropped:0 overruns:0
          TX packets:2724 errors:0 dropped:0 overruns:0
          Interrupt:5 Base address:0xee80 

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        2 eth0
 xx.yy.zz.0     0.0.0.0         255.255.254.0   U     0      0       81 eth1
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0       68 lo
0.0.0.0          xx.yy.zz.104   0.0.0.0         UG    0      0        5 eth1

routed is not running and IP forwarding is off.

Any help on keeping the 192.168. network "private" greatly
appreciated.

Yours,

Stuart
