Hi, My PIX 535 (UR license) is running 6.3(5) version and want to upgrade to 7.X, could any one suggest a stable version in 7.X (It has 16MB flash, and 1GB RAM).

Want to know the difference between both the below commands in detals destination-pattern [1-4,6-9][0-9]destination-pattern 0[1-4,6-9][0-9]
