If so, what is the negate expression. If I want to exclude port 53 from a sig would I put in "!53" or "?!53"?</P> Sun, 10 Mar 2019 09:13:44 GMT https://community.cisco.com/t5/network-security/using-regex-in-signature-tuning/m-p/366967#M97385 gbudgbud7 2019-03-10T09:13:44Z Re: Using Regex in signature tuning https://community.cisco.com/t5/network-security/using-regex-in-signature-tuning/m-p/366968#M97387 <HTML><HEAD></HEAD><BODY><P>There is no regex-like capability in the ServicePorts field. You must explicitly define the ports to be inspected. For example, if you wanted all 64K ports except 53, the setting would be:</P><P></P><P>1-52,54-65535</P></BODY></HTML> Mon, 10 Jan 2005 21:48:00 GMT https://community.cisco.com/t5/network-security/using-regex-in-signature-tuning/m-p/366968#M97387 mcerha 2005-01-10T21:48:00Z Re: Using Regex in signature tuning https://community.cisco.com/t5/network-security/using-regex-in-signature-tuning/m-p/366969#M97388 <HTML><HEAD></HEAD><BODY><P>I'll give it a try.
