OpenWRT or router install

[hooliganshark]

Ah, turns out that there is a lot of info out there about my router eg

I might reach the limit of my linux skills and french knowledge quite quickly

But I can see that if I replace the official firmware with openwrt the DSL modem will not work. So it would be better to continue to use it just as a modem, and look out for another router for running as my minimserver, if someone has had success with one?
