Hi all,
something curious happened to my Network:
all of a sudden, I had to reinstall my WindoozeBox(what wonder). Now when I try to connect to any Edonkey Server, it tells me my port xyz is not reachable. Ok, this is not a Windoof problem, everything worked fine before. I tried a portscan to my PC, which should normally fail, but the side told me I have a private ip, and showed me the IP of the WindoozeBox which is behind SME5.6u4 in Server/Gateway mode. I set the Server to Private Server/gateway and back, but no change, except that there is no Ip shown anymore to the Internet.
May somebody shed a light on this? I searched through the forums with no success. It looks to me like there is no IP Translation running, nut the service is up and running, reboots of the SME didn't help as well.
Thanx in Advance

You may need to post more info on the windows box.
I reinstalled my win98, (seems like it was a mistake
as it now crashes more often) I have my sme5.6 cofigured
as a server only with dhcp, dns, ect. running.
My win98 is setup to be assigned an IP via dhcp and
the sme is my domain controller as well. This configuration
allows me to access the sites on the server using
somedomain.com as opposed to the IP address.
What is your ISP. DSL, dialup, cable? I have sbc and
it turns out that windows is not compatable with
pppOe when on the backside of a firewall router.
However, as long as the sme server is running,
I can surf the web with my win98 box.
My guess is your problem may be in your internet
connection configuration. Is the proxy server running?
That is the first place I would look.

Thanx for ur response Scott,
this is definitely n o Windoof problem, unfortunately.
Since what ever happened, none of the internal Ip are masqueraded anymore.
here is my masq status

Anyway Thanx
