How Ar series routers respond to Network Viruses

The router function is to maintain network connectivity and forward data packets as much as possible. Routers cannot identify a large number of spam messages sent by network viruses.
We need to manually configure the ACL, such as the recently popular Shock Wave virus. Through configuration, the router can partially block these spam packets.
Disable TCP packets with port 135
Disable UDP packets with the port number 69
Disable ICMP Packets

The above is only an auxiliary measure. The fundamental solution is to eliminate the PC virus and install the Microsoft operating system as soon as possible.

Ding, upgrade the virus database of the antivirus tool to improve security awareness.

2. Common Anti-Virus ACLs, including common virus ports. For newly discovered viruses, you must manually add the corresponding ports.

.

Virus attacks may come from the Internet or the Intranet.
