Firewall/NAT

dear sir,

appreciate if any one can provide a solution for this strange issue.

rules are as follows

for LAN network

protocol	source	port	destination	port
*	LAN	*	*	*

for WAN1 network

protocol	source	port	destination	port
*	172.16.32.0/16	*	10.99.1.200	*

for WAN2 network

protocol

source

port

destination

port

for firewall NAT
advanced outbound NAT is enabled

Interface	source	Destination	taget
WAN1	10.99.1.0/24	*	*
WAN2	10.99.1.0/24	*	*

we can ping to the hosts in WAN2 from LAN.
can access the server application on WAN2 from the client application on LAN


we can ping to the hosts in WAN1 from LAN
can access the server application on WAN1 from the client application on LAN
but without adding static route in gateway 172.16.32.94 the hosts in the WAN1 receives no response from 10.99.1.200.
after adding static route to gateway 172.16.32 hosts in WAN1 network receives ping reply.

but still the server application on WAN1 gives error that it cannot receive response from Client on LAN network (10.99.1.200)


requirement for the setup is: how do i add direct route without NAT between Client on LAN 10.99.1.200 to WAN1 network .

thanks
