ip forward

Fri Dec 18 11:05:43 UTC 2009

Did you change the HW ADDR to reflect your MAC address?

Like this:  HWADDR=00:18:8B:DB:7E:9E

Make a new network script

Do it like this:

Cat /etc/sysconfig/network-scripts/ifcfg-eth0:0 

# Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet

DEVICE=eth0:0

BOOTPROTO=none

BROADCAST=199.23.200.255

HWADDR=00:11:43:37:06:D5

IPADDR=199.23.200.90

NETMASK=255.255.255.0

NETWORK=199.23.200.0

ONBOOT=yes

TYPE=Ethernet

I still do not succed to have the needed result.

[root at localhost ~]# ping -I eth0:1 www.google.com

	Don't you need to have your 2nd interface be physical, not an
alias?

	Hi list
	In my school, I need to have a PC that act like router since I
have not public addresses.

	I have followed many link
(http://www.ducea.com/2006/08/01/how-to-enable-ip-forwarding-in-linux/,
the doc of fedora ....).
	All tell the same thing.

	Unfortunally, When I follow them, I have no results! When I ping
an adsress from a windows PC (192.168.10.7) I have no response.

	here is my configuration.

	Can you help plz

	Regards
	ps: I am on fedora 10 and iptables is disabled.
