Redirect IP to specific node or gateway

Thanks Claudio, I had tried that with no success. Heres where Im at now - my irule looks like the following:

when HTTP_REQUEST { if {[HTTP::uri] contains "blocked_url" } { pool ISP_Router_Pool snat automap } }

Thing is, this seems to work if I use speedtest.net for example. It will lookup your IP on that site, and it is indeed the Charter address. However, if I use the other URL's, I still cant get to the sites, and I have confirmed that we can definitely get to them on our Charter addresses. So Im still missing something, perhaps in how it handles the return traffic? Or perhaps there is still something in the packet that identifies it as Cogent (which is why I created a pool with just the Charter router and used automap, I thought that would fix it...)
