No one seems to have addressed this yet, but I'd like to introduce the biggest problem to IP based rate limiting: IPv6.
If you (naively) applied the same logic as you do to IPv4 addresses to IPv6 addresses (i.e. block the address after a certain number of attempts), your rate limiting will be thwarted in about zero seconds.
Why? Well, the simple version ...

If a hacker is in posession of a botnet, they can have control over thousands of IP addresses and can switch between them at will. So there is not really a practical limit to the frequency and speed with which they can change IP addresses.

and if its structure is broken, then entire message is considered broken. This doesn't necessarily say if encrypted data was additionally tampered.

The first question is: What kind of service responds on that port, and what protocol does it respond with?
The second question is: Are there known vulnerabilities regarding to that particular service or ...

Let's take this from Tor backward.
Yes using Tor is likely going to maximize your privacy and anonymity. That said, Tor comes with usability issues that may not be worth the pain for your needs. You can try Tor easily enough by downloading and running TBB (Tor Browser Bundle). Anyone who can access the router traffic can see that you are using Tor but no ...
