PBR / set ip next-hop

Question

Hi,
could someone please advice how to change a next-hop for incoming SMTP traffic? I've successfully created PBR to redirect customer SMTP traffic to a different next-hop:
C6509#access-list 150 permit tcp 85.175.191.0 0.0.0.255 any eq smtp (customer LAN is 85.175.191.0/24; from customer to the internet)
C6509#access-list 160 permit tcp any 85.175.191.0 0.0.0.255 eq smtp (from the internet to customer LAN; doesn't work!)
C6509#route-map MAIL-Redirect permit 10
C6509#match ip address 150
C6509#set ip next-hop 20.10.10.10
C6509#route-map MAIL-Redirect permit 20
C6509#match ip address 160
C6509#set ip next-hop 20.10.10.10
C6509#interface Vlan100
C6509#ip address 85.175.191.1 255.255.255.0
C6509#ip policy route-map MAIL-Redirect
Redirect customer SMTP traffic from inside to the internet works as expected:
IP: s=85.175.191.111 (Vlan16), d=173.19.66.27, len 60, FIB policy match
IP: s=85.175.191.111 (Vlan16), d=173.19.66.27, len 60, PBR Counted
IP: s=85.175.191.111 (Vlan16), d=173.19.66.27, g=20.10.10.10, len 60, FIB policy routed
C6509#sh access-list 150
Extended IP access list 150
    10 permit tcp 85.175.191.0 0.0.0.255 any eq smtp (17 matches)
But the other direction (SMTP traffic coming in from the internet to 85.175.191.0/24) seems not working:
C6509#sh access-list 160
Extended IP access list 160
    10 permit tcp any 5.175.191.0 0.0.0.255 eq smtp
Any ideas?
Thanks,
Thomas

I think it's because PBR must be configured in interface receiving traffic; try configuring PBR on the  WAN interface (obviously you can split the route-map in the routemaps: one for incoming traffic (used on WAN inertf) and one for outgoing traffic (used on VLAN 100))
Let me know, bye,
