A "=>" shows the current selected gateway. + +The second column shows the total TQ value towards this gateway (255 is the maximum and 0 is dead). + +The nexthop column shows the best first step towards the gateway in the first column. The gateway is a direct neighbor which can be reached directly if the nexthop column is identical to the gateway itself (on a per line basis).

The raw number (e.g. 49) is the received gateway class information and translates to the value next to it (4MBit/1024KBit => download/upload speed). + +The "gateway failures" column gives you information about the gateway behaviour. This number is increased if the gateway does not respond to tunnel ip requests or does not forward the traffic to the internet. If the blackhole detection increases this number the current gateway will be ignored during the next gateway selection, so that a malfunctionning gateway is not chosen again (unless you have one gateway only). If the gateway failure numbers keep increasing you can use debug level 3 to find the reason for that. \ No newline at end of file
