Wired routing problem

Wired routing problem

[star fire]

Dear group,

I intend to use iptables in order to limit access
trafic from our head office network(HON). The config
is as follows.

Firewall/Router

eth0
----
IP       10.2.248.1
MASK     255.255.248.0
B'CAST   10.2.255.255
Network  10.2.248.0

eth1
----
IP       172.16.1.1
MASK     255.255.0.0
B'CAST   172.16.255.255
Network  172.16.0.0


Client A
--------
IP       10.2.255.254
MASK     255.255.248.0
Gateway  10.2.248.1

Client B
--------
IP       172.16.1.3
MASK     255.255.0.0
Gateway  172.16.1.1

The firewall/router is a Redhat Linux 2.4.18
The situation where there are no iptables
running(stopped the service) and packet forwarding is
enables via sysctl.conf. As long as there are two(2)
machines as client A and B they connect to each other.
But then again when there is a CISCO route taken in as
a client, client A/B it does not ping to the router
from the other side. Could someone help me on this
issue.

Thanks sna regards

Okay, I understand what you mean by the above configuration, and it works.

Please explain where the Cisco router fits into the above network setup, what 
IP addresses it has, and what the routing table is on all machines involved.
