TCP

Send RSTs

TCP contains six control bits, with one or more defined in each packet. RST is one of the control bits. The RST bit is responsible for telling the receiving TCP stack to immediately end a connection. Sending this flag may pose a security risk. Select Off to disable the sending of the RST flag.

ICMP

Enable

Internet Control Message Protocol (ICMP) can be used as an error-reporting protocol between two hosts. Commands such as ping use this protocol. Sending and processing ICMP messages may post a security risk.
