vshield NAT issue

Hi Everyone

I really need help in this -

is there anyone who is vshield guru in this forum?

we have been using vshield as a 3 tier firewall and need assistance with NAT so that group office can come into DMZ zones through MPLS link. we have manage to get upto  Internal >>> DMZ 2 (both incoming and outgoing traffic) >>> but DMZ1 traffic can come in however cant go out.

internal firewall 10.50.XX.XX

DMZ2 192.168.0.XX

DMZ 122.56.XX.XX

MPLS traffic 10.48.XX.XX

i can explain more if someone is willing to help.

Thanks
