NAT & DHCP on C1760 with switch/InterVLAN routing

Question

Hello,
trying to achieve following (see also Connection diagram.txt attachment):
There is satellite link, which goes to receiver.
Receiver is connected to Cisco 1760 router via switch. From router on serial interface there is one way outgoing satellite link.
On switch between receiver and router resides customers with public and private IP addresses, which can access Internet. Here I do not have problems, using DHCP for assigning private and NAT on stick, everything just works.
Problem is too achieve NAT working on switch (WIC-4ESW), which is inserted into Cisco1760.
Most important that other DHCP pool should be assigned here, we need to use other NAT pool (to split public IP assigned).
DHCP started to work, NAT is working only one way - from private to public IP address.
When reply comes to public IP which should be translated again, it does not.
I see that packets come on VLAN40 interface (see also configuration file of router), but do not see translation happening.
Right now in configuration NAT for VLAN40 is done using NAT on stick.
I also have tried plain NAT (using serial0/0 as NAT outside, no policy route on VLAN40) - result is same.
May be tried to achieve is practically not possible?
Thanks!

Hello,
looking at the configuration of your router, I do not see access list 110, which should be matched in your route map:
access-list 10 permit 192.168.200.0 0.0.0.255
access-list 11 permit 192.168.100.0 0.0.0.255
access-list 100 permit ip any 193.100.100.0 0.0.0.3
access-list 100 permit ip 192.168.200.0 0.0.0.255 any
route-map NAT_Internet permit 10
match ip address 110
set ip next-hop 192.168.1.2
Can you check if this is a typo ?
