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... Regards, Milan -- No need to mail me directly. Just reply to mailing list, please.
