Thread: Additional info about portforwarding Siemens SL2 141

If your router is configured in bridge mode right from the beginning, then you won't get the "NAT(Virtual Servers,Port Trigger,DMZ)" configuration options under Advanced Setup.

You have to first enable PPPoE in the first page of Advanced WAN Setup (Keep LLC/Snap-Bridging enabled at the bottom), feed in PPP username & password on the next page, use dataone as PPPoE service name, authentication method as PAP and enable the last item at the bottom of this page (Bridge PPPoE Frames between WAN & Local Ports), enable NAT and Firewall on the next page keeping all other options as it is, save and REBOOT your router.

Open your SL2 141 configuration menu once again and you will see that the "NAT(Virtual Servers,Port Trigger,DMZ)" configuration options are now available under Advanced Setup. Now configure the virtual server as described in the thread "configuring port forwarding & accessing advanced options in SIEMENS SL2_141" started by whitestar 999 (Look at the attached zip file).

Keep in mind that the start port and end port is exactly the same as the port said to be available in your utorrent preferences/speed guide and that the protocol is TCP/UDP. This is the case for both External and Internal ports. Although whitestar 999 has shown how to trigger the port, I don't think this is mandatory because I got my utorrent port forwarded without going into that.

However, it is probably safer to port trigger in terms of security, but a strong firewall like Kaspersky could make that redundant. Also another thing I did was to disable UPnP in both utorrent and in my Siemens configuration.This is as suggested in the tutorial given in Portforward.com.

Now Reboot your router once again and then check whether your port is forwarded by clicking the test button in utorrent.

Thanks.

Under bridge mode, NAT/DMZ option is disabled because it is not required. In a bridge mode, the modem acts as a pure pathway to internet. All ports are open.

Thank you for editing. Will format my posts henceforth for better readability. By the way, I would like to know whether port triggering is absolutely necessary. Can you shed some light on this?
