Re: IP Inspect Issue

You may need to inspect java applets. It may depend on what version IOS you're using and if it supports the following command, but try:

access-list 1 permit any

ip inspect http java-list 1

Re: IP Inspect Issue

Hello,

Your problems may be caused by out-of-order TCP segments. Until IOS 12.4(11)T, the IOS Firewall drops any out-of-order TCP segments. Since the indicated IOS version, there is a support that prevents such segments from being dropped. It is possible that depending on your network location, the segments are indeed being reordered, resulting in drops.

Also, in periods of low network load, you can try using the various "debug ip inspect" commands to see if the debugs give you any further indication of what is wrong with your connection.

Best regards,

Peter
