I am using a 2811 router with 12.4(15)T5 Advanced IP.
When enabling inspection on my HTTP out rule, several common websites do not funcion properly. This is not a problem on our other 2811 routers not using Zone-Based firewall. One example site that consistently does not work is ft.com.
I have played around with all the inspection settings, including setting it to allow rather than drop and the site still does not work.
Help is urgently needed.
