Rate Limiting on ISP router

Unanswered Question

Hi,


We have multiple internal lans/networks sharing a common internet pipe/link terminated on a Cisco router.


We have seperate NAT IPs ( Public IPs ) configured for each network to differentiate them from one another outside the firewall.


My requirement is like this ,


1) I want to do a QOS on my internet router by restricting a maximum of 1 Mb internet bandwidth for each internal network.


2) Presently i have configured a rate-limiting command on my interface with a matching ACL.

!

interface FastEthernet0/1

description ### MY ISP facing interface ###

ip address xxx.xxx.xxx.xxx 255.255.255.252

rate-limit input access-group 101 1024000 64000 64000 conform-action transmit exceed-action drop

rate-limit output access-group 102 1024000 64000 64000 conform-action transmit exceed-action drop




access-list 101 remark ### input ACL 4 BW Cap test for network1 ###

access-list 101 permit ip any host network1-NAT-IP

access-list 101 remark ### deny any any ###

access-list 101 deny ip any any

access-list 102 remark ### output ACL 4 BW Cap test for network1 ###

access-list 102 permit ip host network1-NAT-IP any

access-list 102 remark ### deny any any ###

access-list 102 deny ip any any


3) What will happen if i add one more NAT-IP in my rate-limit matching ACL as shown below.


access-list 101 remark ### input ACL 4 BW Cap test for network1 ###

access-list 101 permit ip any host network1-NAT-IP

access-list 101 remark ### input ACL 4 BW Cap test for network2 ###

access-list 101 permit ip any host network2-NAT-IP

access-list 101 remark ### deny any any ###

access-list 101 deny ip any any

access-list 102 remark ### output ACL 4 BW Cap test for network1 ###

access-list 102 permit ip host network1-NAT-IP any

access-list 101 remark ### input ACL 4 BW Cap test for network2 ###

access-list 102 permit ip host network2-NAT-IP any

access-list 102 remark ### deny any any ###

access-list 102 deny ip any any




!! a) Will my second network ( network2-NAT-IP) will also have a maximum BW cap of 1 Mb

!! b) Is so can I add all more QOS needed NAT IPs to this matching ACL.


Any help regarding the same is appreciated

b) You can more networks.
