A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.A router is connected to two or more data lines from different networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.
The most familiar type of routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, software-based routers also exist.

    Should I update to SRM 1.3.1 Update 1?

    RT2600AC SRM1.2.5 has been working fine, and I'm afraid to update to SRM 1.3.1 Update 1 since I understand you can't go back.

    Ways to detect upstream network failure for log

    Can anyone think of a way to detect upstream network failure from SRM. Maybe a periodic ping with a log entry for no-reply with time and date stamp. I have a new ISP and I think I am getting some network failures and I want to detect them directly from my router. Thanks, David

    Do Firewall Rules Prevent IPs from Reaching Threat Prevention?

    If the Firewall has a rule to block an entire IP range, say, will Threat Prevention still react to threat IP in that range or do those IPs blocked at the firewall not reach TP?
