Alright then, lets back up and get to straight answers so we can work
this out.

You said that you did not have a router or a firewall but you have a
local network addr of 192.xxx.xxx.xxx.

1. What type of internet service are you on? (broadband always on, dialup).

2. Does your modem have a built in router and/or firewall?

3. If you modem does not have either, and you do not have a router, how
are you getting all your pc's online? (internet connection sharing isnt
going to work long)

4. Click on System > Administration > Network Tools
On the first tab under Network Device make sure your Ethernet Internface
(eth0) is selected. Now look below that in the IP Information area. You
should see the ip of your computer to the right of the IPv4 protocol.

5. On the Port Scan tab of Network Tools, put in first your ip address
from the step just before this and this will tell you what ports are
open. Next do it with 127.0.0.1. You'll probably have a few more.

6. You have WINE install and running.. did you test it with some other
app? Echolink may NOT be connecting correctly to the net via WINE. I
have read about many apps which cant access the net - though IE5,6 both
do through WINE.
