I can not make, for the sake of any source I have checked, make the RB493G connect to a Modem configured as Bridge RFC 1483 or 2684. Note that I have 2 modems of different brands, and both won't work.
I have tested both ADSL2+ modems directly connecting these to my laptop, but only the RFC 1483 based one made up for a connection. After some deeper investigation including my google brain extension, it seems there is a bug in the linux br2684 module preventing from connecting to my actual ISP (Free, proxad in France/Paris region).
Here are the 2 Modems I tested:
Netgear DM111P: 2684 Bridged, VC MUX (VPI/VCI) : 8/36
D-Link DSL-320B: RFC 1483 routed VCmux, (VPI/VCI) : 8/36
Anyway. The only way i can get something to work is to configure the DSL-320B in Static IP mode (I think it then makes something like a IPoATM) connection.
Even then, no chance to get it to run on the RB493G (I didn't find anything in the docs either.
On my laptop, the configuration that works looks as follows:
I have replicated this setup on the RB493G.

Anyway - I'm out of options. I tried so much stuff I don't know what is right or wrong at the moment ...

Anyone has an idea what is going on ? or what I'm doing wrong ?
IMHO, the way I have understood it at the moment, my ISP is using IPoEoATM: (DSL (ATM (AAL5 (RFC 2684 bridged (Ethernet (IP)))))). However, I'm unable to get any modem to work so far...
PS: Wasn't there a vote to get some internal ADSL 2+ modules for the routerboard hardware ??? I'd buy one right away !
