Virtual Hosts

Virtual Hosts

[Uwe Eisner]

Hi @ all,

I am starting set up a iptables based firewall (iptables v1.2.5) on a 
Suse Linux 8.0prof machine.
I created a virtual host an eth0, which is eth0:1.

The situation is, that the firewall is a zebra OSPFD-Router (verson 
0.92a), too. And the machine needs a public IP-Address at the internal 
interface as well. How ever, I would like to use internal ip-stack at my 
network, wherefor I need a virtual host, needn't I?

I have same roule at iptables like:
iptables -A FORWARD -d 192.168.0.0/16 -i eth0:1 -j ACCEPT

The script stoped with following error:
Warning: wierd chracter in interface 'eth0:1' (No aliases, :, ! or *)

In same list, it is mentioned, that it works, other guys say, it works not..

Hope sameone can help me..

Thx and best reguards

Why?

You can use iproute2 to set multiple ip's on an interface.

I believe that the newer iptables versions do not have this problem.
