I purchased a 871W ISR for a small business and want to know what's best use practice when setting up security for this type of router.
At the present time I have a static IP assigned to it and can SSH into it from the outside. Is this safe? If not should I setup VPN to access it from the outside? Is there a VPN how-to (or a link) where I can learn how to set it up.
I was also thinking about blocking icmp from the outside. Is this even necessary if I setup a VPN?
Any help is greatly appreciated.
