Consider this path; CCENT - CCNA - CCNA Security- Wireshark, then maybe Juniper and Palo Alto, then on to CCNP & some SANS courses and the CISSP. You really want the CCNA R&S. It teaches you border gateway protocols & WAN related stuff. If you want to do security with a focus on networking you'll want that. Stay focused on the network side of it but you may need to get into the straight up networking side of things first. Others may disagree with me, but generally a good security guy was either a good generalist or focused on a specialized practice, got good at it, then incorporated security into it.
