Anti spoofing on router

[#1]

We are a business that uses PDQ machines for customers to make card payments on. To become compliant on that the provider wants our router to have anti spoofing on it or we will be cut off. How do I get anti spoofing on the router?

This is an urgent appeal as I have until Wednesday 15th March to get this sorted.

Many thanks in advance for your advice.

I don't believe it's possible using the standard router we provide, you may need to look at a 3rd party router for this feature.

@adamlyonspolice - If it helps DrayTek supports anti IP spoofing within their range.
