I have 2811 with Advanced Security IOS 12.4.23
Router is connected directly to internet. Users are translated with PAT to internet. When I enable ip inspection
(ip inspect name my-ios-fw tcp
ip inspect name my-ios-fw udp)
any file download from http slows down almost immediately till it reaches 20-30 bytes/s. If I remove inspection from users' interface I can download files in without any problem
can anybody help me?
