I activated a 30 day trial of ProtectLink Gateway on my RV042, but after 4 days the router is just blocking all websites. In fact, I bought 7 units of the RV042 to connect gateway-to-gateway our 6 branch offices. I don't know why the routers work right at the begin and after is blocking all URLs. Well, I need to use a dynamic URL and email scanning. If this software works well, I really like to purchase 60 full subscriptions. Could you help me?
