New router request

Hello, friends

I've been running a server lately. The bandwidth has been increasing on it, and eventually I upgraded to FiOS Quantum to suit my needs.

But then I discovered: I'm having another issue!

The router blocks /every/ UDP connection on the grounds that it is a DDoS attack. Why? 

My nat table is around 30,000 items.

I have an MI424-WR Rev. F.

I would like a Rev. G, or for that matter, any verizon router that has a higher NAT table than 30,000. (Those westells look nice, do I get one for free?)

I'd also appreciate knowing how expensive this is going to be.

Thank you in advance.
