Subject: ip forwarding issue with dual gateway
Date: Fri, 06 Nov 2009 16:25:08 +0530	[thread overview]
Message-ID: <4AF4008C.8070204@infoservices.in> (raw)

Hello,

First of all I request you to bear with me as I am not a network guru.

I have two lan cards in my server which is used to share internet
connection with the help of iptables. The config is as below

``````````````````````````````````
echo 1 >  /proc/sys/net/ipv4/ip_forward

iptables -A FORWARD -i ${WAN_IFACE} -o ${LAN_IFACE} -s 192.168.0.0/24 -m
conntrack --ctstate NEW -j ACCEPT
iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A POSTROUTING -t nat -j MASQUERADE
~~~~~~~~~~~~~~~~~~~~~~~~

The setup is working well.  I have one more internet connection which is
cable based so no modem. Hence I again need 2 cards one to connect with
the ISP and forward it to another card which will act as gateway ; just
like above config. The question is shall I follow the above
configuration for the second internet connection ? Is there any
possibility of conflict between the two connection then ? I don't need
any load balancing setup but a setup where I can get the two internet
connections separately.  Please enlighten me. Thanks
