Re: How to configure Lease line and ADSL

Hello,

in order to manipulate the traffic flow, your best option is probably to implement policy routing, where you tell the router to send certain traffic out one interface, and other traffic out another interface.

The access lists that define which traffic has to go where can become a little tricky, depending on what you want, here is what I think the configuration should look like, based on the information you have provided:

interface FastEthernet0/0

ip policy route-map TRAFFIC

!

route-map TRAFFIC permit 10

match ip address 101

set interface Serial0/0/0

!

route-map TRAFFIC permit 20

match ip address 102

set interface Dialer1

!

route-map TRAFFIC permit 30

!

access-list 101 permit tcp any any eq smtp

access-list 101 permit tcp any eq smtp any

access-list 101 permit tcp any any eq pop3

access-list 101 permit tcp any eq pop3 any

!

access-list 102 permit tcp any any eq www

access-list 102 permit tcp any any eq domain

access-list 102 permit tcp any any eq ftp

access-list 102 permit udp any any range 5000 5010

access-list 102 permit tcp any any range 5000 5001

As I said, the access list might become tricky. Outlook Web Access, for example, use the common WWW port 80 as well. Also, you will need to find out which ports your VPN is using, and add those to the access list.

By the way, UDP ports 5000 thru 5010 are used by Yahoo, if those don't work, it will try TCP port 5000 thru 5001.

Let me know if you run into trouble with this, or if you need more help...

Regards,

GP
