I think i'Ve found the problem.
my monitor ip where all the same for all gateway.i've checked the routing table and the route for the monitor ip was rl3.
that should explain the problem. weird that it worked since version 0.6.what should be the monitor ip ?
if my gateway is 201.120.51.1, can I use 201.120.51.1 as the monitor ip ?thanks
It will add a route for the monitor IP to the refferenced gateway. If you enter always the same monitor IP for all gateways it will overwrite the previous route and you'll end up with only one route. The monitor IP should be different for each gateway. You should set the monitor to a hop near you at the appropriate interface. Depending how your connection is set up the gateway IP or the first hop after your gateway might be a good choice.
