I am trying to DPI inspect on HTTP for port_violation and port_misuse with IOS ZFW. Does anybody have experience on that?
What's happening the DPI seems to be working but I am having troubles to open any websites, I get bunch of messages type: %APPFW-4-HTTP_PROTOCOL_VIOLATION and %APPFW-4-HTTP_DEOBFUSCATION. I get those messages when I only browse for websites, no other programs like p2p or im are running to trigger RESET rule on DPI. What's most funny is when I run p2p like bittorrent the trackers connections don't reset, they are just keep flowing through the router.
Any suggestions would be great.
