Linux Server NOT Gateway

[cedricmark]

Hi,

I got ADSL. I connected the modem to a Windows PC (since I found no Linux drivers). I want to have a Linux server serving email internally, and http/ftp/ssh externally (internet users).

I cannot hink of a way to do this, even more for the fact that should the line go down, my IP will change, but it is not dynamic during th connections.

Is my want list too compilcated ?

Using Windows 98/2000 and REdhat 7.1

You need a generic proxy and port forwarding, (redirection), unless you can get your provider to give you couple of public ip addresses.
I am not a fan of MS and do not know their
product line well enough to tell you what may
or may not be available to do this for you.
I am sure some third party firewall probably
has what you want.

Hi,

Firstly, you would need to use one of those dynamic ip posting utilities - see

http://www.digifriends.com/apps/msc-ippo.shtml

for some examples.

There is an implementation of nat included with Win2K server (but not win9x/NT/W2k professional). However, I don't think it can cope with the external IP address changing - its just a direct swapping of an external address to an internal address and vice versa. This would work fine if you had a fixed ip address and wanted to route certain traffic to an internal box.

I believe (haven't personally tried it) that winroute does port fowarding, etc., on win9x/w2k boxes so you might want to look at that :
