Networking :: Speedport W503v C And MANDRIVA2009.1 - Http Works - Ssh Not

Objective: access from internet to http and ssh service on LINUX PC with MANDRIVA2009.1 OS in small home net.

Home net: Telekom DSL router w503v version C with direct connections to WindowsXP system, MANDRIVA2009.1 system and Dlink wlan access point. wlan of w503v not active.

MANDRIVA PC has running ssh and http servive, working well in intranet, using fixed IP addresses in same area as w503v (192.168.2.xx).

Did several trials to enable access to MANDRIVA PC from outside via DSL router. Last trial is as follows:

1) http forwarding (Weitereitung) on port 80 to proper 192.168.2.xx

2) ssh redirection (Umleitung) on port 24 to same IP address.

Here it should be noted that http is using predefined web-server in the router and that "ssh" is specified in an empty input box (offer is only second web-server).

For DNS the DynDNS support is successfully applied with manual adjustment of provider IP address.

Result:
- In intranet, i.e. clients with IP address 192.168.2.xx both http and ssh work with resolved DynDNS name.
- In internet http works without observed problems, shh is not responding on port 24. Also ping does not work.
