And another country heard from .... Linky routers do not do stateful packet inspection. To protect a home network with PC firewalls installed and little or no risk this is adequate. Better to get a firewall router that does the job, for a few dollars more, like a Checkpoint. It will do your stateful packet inspection and block attacks with known signatures. And then add an IDS or IDP to the config so you can find out who and how to protect yourself from. Then you can have some continuity to your business operations.
This is a large scale problem. Better start a project and do the research, send out RFPs to get vendors to respond to your needs, then decide on the best course of action. Offloading the specs to a vendor seems like a wise way to go in your case. And remember to "trust but verify".
