Speedtouch 780WL used as WLAN router only

Hello,

back from my time in Scotland I still have a Speedtouch 780WL, which I
used with Freeola. I already learned that I will not be able to use the
DSL-modem functionality here in Germany (Annex B vs. Annex A on the
device).

Has anyone be able to configure the 780WL, so that I can attach it to a
normal DSL-modem.

DSL-modem -> Ethernet cable -> 780WL -> WLAN

Thanks in advance

Thanks, that looks very promising. Does a factory reset also kills all
such changes done by the cli? Just for the case that it doesn't work and
I have to start again.

Interesting stuff to read. Thanks again.

I've made several tries with this chain of commands (and also others
which I found on other places). I was able to convert a LAN port into a
WAN port. However, I didn't managed to to get an Internet connection
through this configuration. Do I have to give any IP onto the DSL modem
or does the speedtouch automatically uses the WAN port as default
gateway?

without reconfiguration of one LAN port into a WAN port?

In an ordinary router having an ethernet WAN port, the router will contain a
routing table to direct traffic from the LAN which is addressed to the
router out of the WAN port. Sometimes the WAN port will have an IP address,
sometimes it will be bridged to the separate modem. Either the modem itself
will give the WAN port an IP address, or the ISP will give the modem an IP
address which is then bridged through to the WAN port.

I'm not familiar with the command language for the Speedtouch but at a
glance the commands for the version 6.1 firmware look like they should cause
the WAN port to get an IP address. The key will be whether the router then
builds a routing table that does the right thing, and implements NAT.

There should be commands which will show what the router is configured to
achieve - these might help you get the configuration right ...

That's correct, without a question. Unfortunately I don't have it,
because the installation hasn't been done yet.

Well, wat the ISP recommends is very clear. You should "buy" their
hardware. Unfortunately you don't buy it, but only rent it for a one-off
payment. Which I consider to high for the provided functionality.

The installation will be made Thursday next week and then I will be able
to make tests on the real installation. Let's wait and see.
