I am trying to setup Dual WAN in our office because our single VDSL modem couldnt handle our web traffic any longer. So we now have two VDSL modems (Sagecom FAST2864) they cant go into bridge mode because they are locked down by our ISP. So I have to settle for disabling DHCP and WIFI on them and setting a static address on my cisco router.

My topology looks like this ....

enter image description here

My issue is when both links are active and you try to browse the internet it takes 3 or 4 page refreshes before all the content loads. When I disable one of the links everything works fine! I have tried with both ip load-sharing per-packetand ip load-sharing per-destination both result in the exact same issue. I have posted my config below any direction on this issue would be very helpful as I am currently paying for a extra VDSL connection that is sitting unused.

In this case, you can using route-map, create a policy for groups of clients. Some thing like this:

Define ACL:

ip access-list extended FirstLink
permit tcp 10.1.1.10 any eq www
deny ip any any

Define route map:

route-map FirstLan permit 10
match ip address FirstLink
set interface Fa0/0

Apply it to LAN interface:

interface FastEthernet1/0
description LAN
ip policy route-map FirstLan

But this requires you have another LAN interface to (Fa1/1) to make others hosts to go through.

For truly Load Balancing in this case, you can use pfr/OER

  • Will PFR/OER solve the HTTP session issues? Aug 9, 2013 at 17:01
  • From this doc: http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/Transport_diversity/PfR_Master_Controller_Redundancy.html I think the answer is yes.
