Poor upload/download speed on 2 x ADSL lines into a Cisco 2621XM

Sorry never been on this site before so I apologise if not the right section or even forum.

I have users complaining of very slow internetn connectivity on site and have checked with our ISP who have said that the line is testing at 8mb.

We have 2 x BT lines that have our ISP broadand on them. Both lines go into a Cisco 2600 series router that then has a PIX firewall off that. Connectivity is successful just gone really slow and unable to download anything.

Config is below:

Now my knowledge is very limited but ISP have said that while the lines are bonded each needs a seperate login as they've recently changed their L2TP router and that enforces the use of seperate logins - when the lines were configured we were given two logins.

So, my question is what changes do I need to make to the config in order to get this working? it was ok before their change and I do have another login :-

01270 111111 - bond1@ISP.net
01270 222222 - bond2@ISP.net

Does the IP address for dialer1 need to be the same as dialer0 as its just the authentication that is the problem?

Do I need to make a change to ip route 0.0.0.0 0.0.0.0 Dialer0 as I've created another dialer interface?

current config below:

Apologies for the long question and thanks for taking the time to read it. Any more info I can provide please let me know.

• I think what you need to add is another dailer interface like this:

  interface Dialer1
   ip address x.x.x.x 255.255.255.248
   encapsulation ppp
   dialer pool 2
   dialer-group 2
   ppp authentication chap callin
   ppp chap hostname bond2@ISP.net
   ppp chap password 7 xxxxx
   ppp multilink
  !
  

  then you use the new dailer pool for the second ATM interface.

  interface ATM0/1
   description 01270 222222
   no ip address
   no atm ilmi-keepalive
   pvc 0/38 
    encapsulation aal5mux ppp dialer
    dialer pool-member 2
   !
   dsl operating-mode auto
  !
  

  Modify and fill in as needed. You might want to have a look at the cisco ios documentation: http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcdbakdp.html#wp3753

  From pehrs

• sorry me again, i'll have to try this after 5pm as any changes may affect current users.

  Just wanted to confirm something

  Does each dialer interface have to have a seperate login? your answer uses the same login as existing setup but thought I needed a seperate one? I've been given:

  01270 111111 u/n bond1@dsl.net (currently being used on Dialer0) p/w password

  01270 222222 u/n bond2@dsl.net p/w password

  Thanks Again In Advance,

  MarkM : Please make an edit to your original question as opposed to writing this in the answer section. You may want to read the FAQ link, located at the top of the page.

  2020mobile : thanks for that, sorry for the mistake

  pehrs : The dialer interface specifies the settings used for the connection, including login/password, so you would have to modify what I wrote to include the correct phone number and such, yes.
