Hi everyone. I've set up my home network with two connections to my ISP. They both seem to terminate on the same BRAS, hence using the interface for the route as opposed to the next hop for the route, along with the fact they've given me /32 addresses somehow.
The problem I have is that when using the pppoe dialer interface, I get webpages starting to hang. I can remove the policy map stuff, and just route out of dialer1 with standard NAT, and I still have the same issue. I'll be able to load google, search a website, but clicking on the website will cause it to never load. Have I got something wrong on the dialer1 interface? Is it an issue because it's an ethernet interface and not seen as point to point for routing?
