Regular Expressions in a ASA using version 8.03

[wfleenor]

Questions: is there a way to create a network group using wildcard?

I need to allow access on a 10.0.0.0/8 network that is segmented in 4000 smaller network. However, within these smaller networks only the 10.*.*.11 need to use port (21,137,443). Is there a way of using regular expression or wildcards in access rules?

Neither PIX nor ASA use wildcards. You cannot use regex in ACLs, the only way you can use regex is through MPF:
