hi

you can configure VACL's to achieve your requirement.. But you should make sure that your platform and the ios version/feature set installed in that supports the same..

Look into reflexive access lists.

In summary, they are similar to using the established key word but also apply to icmp and udp. That way, you can have one side with full access to the other, but not vice versa.
