Does anyone know if this works on the 857, tried it and it kicked me out of the router
ip nat inside source static 192.168.60.10 172.16.181.195 route-map MAP extendable
2. Define the port range
access-list 101 permit tcp host 192.168.60.10 range 8000 8050 any
route-map MAP permit 10
match ip address 101
