I have a new problem. Although not entirely iptables related, I use it for iptables.
I have 2 network cards: 1 built-in intel with the motherboard and 1 3com 3c509x.
I was gonna use the 2 nics for iptables.
Now the problem comes when assigning ip addresses and rules based on network cards.
eth0: 192.168.247.233 - internal lan, no gateway
eth1: 192.168.247.232 - external access, with gateway access
I have squid running on the server. When people try to use squid on 192.168.247.233 they can connect properly but I notice on /var/log/kernel that IN=eth1 DST=192.168.247.233
And "route" gives me:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.0.0 U 0 0 0 eth1
192.168.0.0 * 255.255.0.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.247.1 0.0.0.0 UG 0 0 0 eth1
I can't seem to find my eth0 in the route function.
ifconfig produces the correct settings:
eth0 Link encap:Ethernet HWaddr 00:02:55:EE:C3:91
inet addr:192.168.247.233 Bcast:192.168.255.255 Mask:255.255.0.0

On pinging 192.168.247.233, it produces a successful result but when I pull the plug on eth1 it stops working. So why does ifconfig say 192.168.247.233 is on eth0 when I pull the rj45 on eth1 it stops responding?
/etc/modules.conf says:
alias eth0 eepro100
alias eth1 3c59x
Hope you can help me again. Thanks.
