-**Enable TCP SYN cookies** - Enabling this protects the router from SYN Flood attacks via a well-known technique called "SYN cookies". This function encodes information from the SYN packet into the response (SYN/ACK). Despite being a standard technique, enabling this will create some secondary limitations that may not be handled well by some old TCP/IP stacks.+**Enable TCP SYN cookies** - Enabling this protects the router from SYN Flood attacks via the well-known "SYN cookies" technique.

 **Enable DCSP Fix** - This enables a workaround for a well-known issue related to DSCP (packet marking) when connected to the Comcast ISP. **Enable DCSP Fix** - This enables a workaround for a well-known issue related to DSCP (packet marking) when connected to the Comcast ISP.

-**NAT loopback** - also known as "Hairpinning", this technique allows LAN devices to access another LAN device via the WAN interface of your router. This is common practice, for example when connecting to the DDNS domain of your router from the LAN (for administration purposes). This legacy setting is rarely, if ever needed nowadays. It also can create a bottleneck on fast connections.+**NAT loopback** - also known as "Hairpinning", this technique allows LAN devices to access another LAN device via the WAN interface of your router.
