I have the following network layout:

with the following network configuration:
ROUTER1 (asus rtn66u router):
- knows about 192.168.0.0 network via 192.168.1.1
- ssh tcp 22 on WAN redirected to 192.168.1.1
ROUTER2 (asus rtac3200 router):
- knows about 192.168.0.0 network via 192.168.2.1
- ssh tcp 22 on WAN forwarded to 192.168.2.1
MIDBOX:

# QUESTION #
##########
I've created the 'rtnac3200' table so that I can ssh into MIDBOX from EXTBOX no matter what router I use.
The problem I have now is that from INTBOX I get no replies when I ping 192.168.2.1 (any other interface does reply though)
How should I modify my configuration to solve this problem?
PS: hopefully I'm posting to question to the right mailing list.--
