Could you post exact sequence of ngctl commands used to create you connection 
from rl0 to ng0? Also, it seems you did breake path from rl0 lower to rl1 
upper hook, this is necessary in order to ping work - think of lower hook as 
ethernet card and upper hook as TCP/IP stack. Without connection (direct or 
via some other node) IP packets can't travel back and forth...
