I usually block all but a very few countries using the geo-blocking feature on the MX-84. It has greatly cut down malicious traffic - (to the best of my knowledge).
I will say at the outset that firewalls are not my greatest skill set.
I have explained that to my users, so if they are going out of country (outside the US) they will tell me and I will unblock that country.
It has worked well so far.
I have two questions:
- I have a user going to Sint Maarten, the Dutch side of St. Martin island. There is a geo-block choice for the french side of St. Martin but not for the Dutch side. How do I block/unblock Sint Maarten? Or is it even being blocked in the first place?
[I have the IP ranges for both sides but it is a very scattered list.]
- Is this the best way to geo-block? Or should I even bother? It seems like it stops a lot of traffic (geo-blocking) and I've got only the countries we need allowed in. I figured the more I can close the "window" so to speak the less that can get through that I don't want in.
