Enable that custom signature. Then telnet from source a to source b. The connection should not be successful and you should see an event in your IPS/IDS reporting application.</P></BODY></HTML> Wed, 10 Aug 2005 21:47:33 GMT https://community.cisco.com/t5/network-security/verifying-tcp-reset-functionality-is-working/m-p/470996#M100091 gabelar 2005-08-10T21:47:33Z Re: verifying tcp reset functionality is working https://community.cisco.com/t5/network-security/verifying-tcp-reset-functionality-is-working/m-p/470997#M100099 <HTML><HEAD></HEAD><BODY><P>I was able to successfully test TCP reset.
