ping bug?

Current scenario working:
RB433 Version 3.13 with 2 cable lines with 25 Mbits each.
Load Balance working based on some tcp/udp ports + nth for http

I need to create a script for failover.
my current route list:
0 A S 0.0.0.0/0 r 10.0.0.2 1 Wan2 “routing mark 1”
1 A S 0.0.0.0/0 r 192.168.1.254 1 Wan1
2 A S 0.0.0.0/0 r 192.168.1.254 1 Wan1
r 10.0.0.2 Wan2
3 ADC 10.0.0.0/24 10.0.0.3 0 Wan2 “routing mark 2”
4 ADC 10.0.1.0/24 10.0.1.1 0 Private
5 ADC 192.168.1.0/24 192.168.1.253 0 Wan1

From winbox if i ping http://www.google.com and select the interface, it works perfect and goes through the selected interface, from ssh, if i do “/ping http://www.google.com interface=Wan1” or interface=Wan2 gives me ping timeout.

Is there any mistake im doing here? Or a bug?
