Hi,

I am trying to make a router using a FC4. I have 2 NICs in the machine. Install FC4 using minimium. Eth0 is set to DHCP, connected to an ethernet modem and ETH1 has IP 192.168.1.1, netmask 255.255.255.0 connected to a switch. Installation was a success and rebooted the box. Clients machines are unable to ping 192.168.1.1. But when i unplug the modem and reboot, clients are ablt to ping 192.168.1.1. I realised if the box booted up both ETH0 and ETH1, clients are able to ping 192.168.1.1. But if i ifdown ETH0 and ifup ETH0, clients are able to get reply from 192.168.1.1.

Can someone tell me what should I do?

Best regards

/etc/sysctl.conf:

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

This is my /etc/sysctl.conf

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled.  See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
net.ipv4.conf.default.rp_filter = 1

# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
