Hi all!
I changed my server running redhat9 (kernel 2.4.x) with a new one with
fedora core 2 (kernel 2.6.x): each one has 2 ethernet interfaces, so I copy
network configuration fron rh9 to fc2


eth0 --> 192.168.1.254 / 255.255.255.0
eth1 --> 82.186.92.90 / 255.255.255.254
eth1:1 --> 82.186.92.91 / 255.255.255.254
eth1:2 --> 82.186.92.92 / 255.255.255.254
eth1:3 --> 82.186.92.93 / 255.255.255.254
eth1:4 --> 82.186.92.93 / 255.255.255.254
also, I copy and apply iptables configuration but it does not work well.
now iptables doesn\'t apply rules to virtual interfaces, eth1...eth4.
a line of my configiguration files is:
-A INPUT -p tcp -m tcp -m state -d 82.186.92.91 --dport 20 --state NEW -j
ACCEPT
I tried different rules configuration but it still not work.

can you help me? --

Have you tried to use the iproute2 suite for aliasing instead of ifconfig? I believe the ifconfig way is considered "deprecated". Then, specify your rules by interface and/or ip and it should work properly - maybe the old method only works in iptables using the interface name now?


example:

## old ip aliasing
##/sbin/ifconfig eth0:0 192.168.0.1
##/sbin/ifconfig eth0:1 192.168.0.2

## New IP aliasing using ip tool from iproute2 package:
/sbin/ip addr add 192.168.0.1/24 brd + dev eth0
/sbin/ip addr add 192.168.0.2/24 brd + dev eth0
