I am unable to configure the TCP Reset on my IPS 4255 in Promiscous mode.
I have declare one interface of 0/0 IPS as tcp reset, for interface gig 0/1.
but still not working. Please tell me how to configure and how to verify the configuration.
Make a custom STRING TCP signature direction 'to server' for Telnet (Port 23). Match on any string like 'abcd'. Now telnet on the SPANNED vlan, and then try to type abcd. as soon as you type 'd' (the last letter) your telnet connection will get stuck :)
