Custom Queuing on Ethernet Interface

Hi,

I have a 1605R router connected to Cable Internet Service. I want to allocate\guarantee some badnwidth to traffic coming from specific internal IPs, 192.168.101.3 and 192.168.101.4.

These IP are being NAT to Public IPs using one-one static translation.

I created access-lists

"access-list 110 permit ip host 192.168.101.3 any

access-list 110 permit ip host 192.168.101.4 any

"

And associated these access list with Custom Queue Lists.

Ethernet0 is connected to Internet and Ethernet1 is connected to Internal network.

My question is

1. Where should the Custom List be applied, Ethernet 0 or Ethernet 1 ?

2. If it should be applied to Ethernet0, then should i modify the Access-list statements to replace the "Internal IPs" with their corresponding "Public Mapped IPs" ? As by the time the Custom-List would be evaluated the Source IP would have been changed by NAT ?

Thanx \\ Naman

Re: Custom Queuing on Ethernet Interface

As per your situation , you will be configuring

IP nat inside in e1

and

IP nat outside in e0

when the packet leaves e1 it will be replaced with global IP address, Hence you can apply the accesslist in internal

Re: Custom Queuing on Ethernet Interface

you mean

"when the packet leaves "e0", and not "e1" as you mentioned, as e0 is the outside interface" ? And any packet going out of e0 will have global address.

I guess i want to clarify if

Custom Priority lists are applied to the outgoing interface ?

OR

Custom Priority lists are applied to the incoming interface ?
