From one Ethernet to the other

I know that the mode should be the same, with a ping should it work?

About the clocks, if I'm only wiring from one connector to the other, should I take care about the synchronization if I'm only connecting one input with one output??

I thought that the mdio is preconfigured in this kit and is not needed to be configured for this purpose, am I wrong?? if yes, I thought that there was an ipcore from altera for this configuration but I do't find it, do I need nios? because I'd to avoid its use

Thank you very very much for your reply =)
