Status Tab
The “Standard System Routing Table” displays the current routes for the Red Lion router and the static routes that have
been configured for the router.
The “Policy Routing Table” displays information on the policy rules, the route tables for each individual interface and the
general routes for the Red Lion router.
3.2.2.5 Socket Statuses
Sockets are end‐points to communication over the Internet. Much like PBX phone systems, where the IP address is the
phone number and the port is the extension. Every paired (connected) socket has a source IP/port and a destination IP/
port.
There are three tables in the Socket Statuses dialog window: “TCP Only”, “Conn Track” and “Socket Statuses All”
The “TCP Only” table displays the sockets that are connection‐oriented (Also known as “stream sockets”).
“Conn Track” is a connection tracker that displays more thorough information about the current socket connections. Con‐
nection tracking allows the kernel to keep track of all logical network connections or sessions, and thereby relate all of the
packets which may make up that connection. NAT relies on this information to translate all related packets in the same
way, and IPTABLES can use this information to act as a stateful firewall.
The “Socket Statuses All” table displays the sockets that are considered connection‐oriented and connectionless (also
known as “datagram sockets”).
3.2.3 Diagnostics
The Diagnostics menu is sub‐sectioned into Cellular Status, Ping, Socket Test, Traceroute and System Info submenus. These
are useful in troubleshooting connectivity of the Red Lion router to the Internet or the Network the router is connected to.
