Just setting up and testing a Cisco 891-K9 router. Used CCP for basic setup, figure I'll tweak any settings needed later.
For the firewall, I chose the default "medium" security setting in CCP, then added some holes (already setup in NAT) for outside access in.
Now on to the real question:
I noticed that I am now unable to click through google search results. On any borwser. Clicking on any search result simply loops back around to the same google search page. If I disable Javascript on the browser, everything works as expected. So it appears that the firewall is preventing something in google's scripts from redirecting and "clicking through" to the final destination page.
I'm familiar with our old Pix firewall commands, but still a relative newcomer to the zone based firewall and commands for this new 891, so any help would be appreciated! (relevant Config pasted below) (Gi0 is the WAN interface)

Sorry to reply to myself, but looks like I found the culprit. It appears it was the following section:
policy-map type inspect http ccp-action-app-http
class type inspect http ccp-http-blockparam
log
reset
Allowing this section (instead of resettting) corrected the issue. I'll leave the further analysis to those more qualified, but I feel I have to ask... What risks am I opening by allowing this through?
Thanks!

Im not a super-expert on the ZFW, but from looking at what the class-map matches:
match request port-misuse im
match request port-misuse p2p
match req-resp protocol-violation
It looks like Google is opening some sort of app on the wrong port...(??)
Never seen it before, but now I got to try it

Yes, i have same problem for this after activated firewall in Cisco Conf Pro 2.7.
im just delete the firewall rule, and solve this. I Think this related for URL cache, its allow 200 Character only.
but i try to add this from 200 Char to 400 char, failed/error in CCP 2.7
well, any other solution ??
