Change Subnet Mask

Hello All,

  I've been tasked to manage an operation that is currently using a /24 mask on the internal interface of an ASA5510.  The current address pool is close to exhaustion so can I change the subnet mask to say a /22 on the internal interface without breaking the current ruleset.  Thanks for any feedback provided

Hello,

When you say ruleset do you mean: Nat rules, ACL checks,etc right??

We would need to check the configuration so we can help you on that one,

Regards
