External/Internal IP

[Guest_imported]

I have 6 servers all running Microsoft 2000 Server Edition.

I am now sick of these because the IIS server is just absolutly crap and apache on linux rules! ;-)

I have 13 external IP's available. 1st Of all I setup an internal ip in network configuration of: 192.168.0.150

I can view this threw all the computers on the internal network.

I then added an EXTERNAL ip into the network configuration on the linux machine and put in the ip of 202.174.40.82

I thought this would work how ever when I restarted the linux machine I went onto all the computers on the network and it would say the external ip didn't exist (yes they were all connected to the net) But i can still view the internal Ip with the apache test page.

I am new to linux can anyone help me out?!?

EMAIL WOULD BE GREAT! michael@apps.com.au

G'day,

Firstly, I'm assuming that the linux box is multihomed, i.e. one interface on lan and one external. Also, from what you say, I take it that the other local machines have a pre-existing internet connection, i.e. independent of this linux box.

This would therefore seem to be a routing or firewalling problem of some sort. In fact, if I traceroute to that IP from here, it stops at x.x.x.14 on the same subnet - presumably a firewall / router .

So, you'd need to check out whatever box has that IP address and the connectivity from that point to the linux box. It could also be that you are (unbeknowingly ?) running a firewall on the linux box itself because most of the latest distros do that by default. For example, redhat 7.x uses 'lokkit' which you administer as root with the command '/usr/sbin/lokkit' . You'd need to permit inbound port 80 to get access to apache via public internet.

Hope this helps
