How to put 2 IPs on a single NIC
Hi !
I've just got a real IP number for my personal computer. Until now, the IP was masked (NAT'ed). Anyway, the problem is like this :
I'm on a LAN with about 100 computers and I asked the admin to give me a real IP so that I can connect to my computer from my office. He gived that IP to me, but the DNS server of the network doesn't have a real IP, so somehow I have to be on the same LAN (from the IP point of view) to can access the DNS server, and I have to be on the other network, beacause the new IP belongs to another network... The LAN has the IP class like 172.17.xx.xx and the real IP is 195.225.xx.xx. So, how may I set this up ?
I tryed with to make an alias on my /etc/rc.conf file (I use FreeBSD 5.3-RELEASE) but it doesn't seem to work... I don't have access to anything... Am I missing something ?
Can anyone, please, give me an example of how should I set it up ?
Thanks.
Bye !

WIRELESS(7) Linux Programmer's Manual WIRELESS(7)
NAME
wireless - Wireless Tools and Wireless Extensions
SYNOPSIS
iwconfig
iwpriv -a
DESCRIPTION
The Wireless Extensions is an API allowing you manipulate Wireless LAN networking interfaces. It is composed of a variety of tools and
configuration files. It is documented in more detail in the Linux Wireless LAN Howto.
The Wireless Tools are used to change the configuration of wireless LAN networking interfaces on the fly, to get their current configura-
tion, to get statistics and diagnose them. They are described in their own man page, see below for references.
Wireless configuration is specific to each Linux distribution. This man page will contain in the future the configuration procedure for a
few common distributions. For the time being, check the file DISTRIBUTIONS.txt included with the Wireless Tools package.
DEBIAN 3.0
In Debian 3.0 (and later) you can configure wireless LAN networking devices using the network configuration tool ifupdown(8).
