Dear all,

I want to reduce bottleneck to our ISP link (256kbps) caused by users' download, etc. Below is my configuration.

interface Serial0/0

ip address rtr.ip net_mask_rtr

ip access-group 100 in

ip nat outside

rate-limit input access-group 104 128000 8000 8000 conform-action transmit exceed-action drop

rate-limit input access-group 105 128000 8000 8000 conform-action transmit exceed-action drop

encapsulation ppp

access-list 104 permit any

access-list 104 deny any

access-list 105 permit any

access-list 105 deny any

ACL 100 is more general (i.e: tcp established, and allowed type of connection). I'm not very confident that above 104 & 105 could help me to limit users traffic, and also it seems to me there are two acls for s0/0 to forward traffic to each local 1.x & local 2.x networks.

Any suggestions and helps will be greatly appreciated.

Thank you.

Best regards,

Seems like this wont stop them from tying up the internet circuit, it will just stop the data from getting throught the router once it has come over the internet link.
