im am now managing a cisco 1841 router with 12.4(1c) ip based ios version. I just found out that this image cannot support firewalll and NAC features. these features are necessary for the operation of my work as a network administrator specially in monitoring as well as advance security monitoring.
im planning to upgrade the existing ios version to 12.4 (1c) advance security ios version to support the given features. will this upgrade solves the issue?
