My router is a piece of shit: pretty sure it cannot do port forwarding or the ISP disallows it somehow. Anyways, if you don't offer anonymous services, fail2ban might be interesting to you, if you haven't heard of it yet?

Dear devs, What do routers really do logically? I was looking for an IPv6 router which is flashed with a small C program, not an OS like OpenWRT and which basically distributes network. It assigns IPv6 addresses to it's child nodes in network and forwards packets based on some identity. Is the
