I have installed a 2851 with 4 x ADSL-HWIC's. Using CEF it is balancing the load across the links. All up it is working well, however there is only one issue at this stage.
On a few web sites you can access things fine except then when you click on a particular link on a problematic site the router logs something like this:
%IPS-4-SIGNATURE: Sig:2001 Subsig:0 Sev:2 ICMP Unreachable [web.site.ip.address:0 -> my.dsl.ip.address:0]
As a result you end up with an error in your web browser (after a timeout period) indicating the page cannot be displayed.
When you access the same site on a different internet connection it works normally. So this seems to only be a localised issue to this 2851 configuration.
Can anyone suggest where I can start looking or what I can change to stop this from happening?
Thanks in advance
