Limit bandwidth by protocol with CAR over VPN

I have a VPN over internet with two Cisco 1710 routers, with NAT. It works fine. But I want to limit traffic over VPN with:

interface Ethernet0

rate-limit inpur access-group 103 8000 8000 8000 conform-action transmit exceed-action drop

access-list 103 permit tcp any any range ftp-data ftp

And with "sh access-list" ftp traffic never matches access-list 103. If I use "access-list 103 permit ip any any" then it matches access-list.

I think the problem is with access-lists based in protocol.

Thanks in advance.

Re: Limit bandwidth by protocol with CAR over VPN

What happens if you put two lines in the access-list, explicitly permitting 21 & 20 rather than specifying the range? Do you get hits then?

How do you know the hits on the second access-list (permit ip any any) are ftp hits? Could they be hits from other IP protocols, after all, "permit ip any any" is quite generic.
