DDoS and blocking IPs

[Fmslick]

So i feel as if i am getting ddos and how do i block IP address's ?

The same ip keeps hitting my network and some others are too…

Those are being blocked - blocked and logged. If you want to stay fat, dumb and happy, you can put a rule above the default rule to block and not log traffic from that IP. But the start SYN (S) packets will still be arriving across your WAN link, you just won't see it in the log.
To stop stuff even being sent to you across your WAN link, there would have to be some firewall at the upstream ISP that you could manage.
