I'm thinking on building my own (micro-atx) router for business and personal projects at home.
My question is what kind of network card do I need to receive the fiber optic connection? I'm currently using the router my ISP provides me but I want to replace it.
I've been looking and I can only find super expensive cards (more than 150-250€) and I think those are not the ones I need, so can anyone point me in the right direction?
I will be using a Linux distro with iptables, dhcp, bind, etc...
