how to allow all port forwarding on router ?

[rechard_hk]

Dear all,

Currently we allow command as below for forwarding port

ip nat pool nat_pool 10.10.10.1 10.10.10.1 netmask 255.255.255.252
ip nat inside source list 1 interface FastEthernet0/0 overload
ip nat inside source static tcp 20.20.20.20 3389 interface FastEthernet0/0 3389

access-list 1 permit 20.20.20.X

BUT now i don't want allow one by one so i want allow all port for forwarding and i will forwarding below this hardware is ASA. 

How can i allow all port forwading on router 2800?

Best Regards,

Why don't you just plug the WAN link directly into your ASA? Then manage your NAT there. Assuming that the router and ASA are in the same location.
