I am trying to connect from Int3 security of 15 to int2 securiyt of 10 however I am having no luck can any one help, if I put in any rules to try and force it through it drops all connections on this interface.
Depending on which way you are going you either need to use the "static" command with an appropriate "access-list" configured (from a lower security interface to a higher security interface) or the "nat" and "global" commands (from a higher security interface to the lower security interface). Examples of how to configure both can be found here:
