A cryptographic device may include a cryptographic module and a communications module removably coupled thereto. The cryptographic module may include a first housing, a user Local Area Network (LAN) interface carried by the first housing, and a cryptographic processor carried by the first housing and coupled to the user LAN interface. The communications module may include a second housing and a network wireless LAN interface carried by the second housing. The network wireless LAN interface may be coupled to the cryptographic processor, and it may be switchable between wireless LAN modes.

In accordance with a nonlimiting example, a network device transfers communications data along a communications channel within an Internet Protocol (IP) network. A communications module includes a signal input connected to the communications channel of the IP network and receives an Ethernet packet having an Ethernet header and IP data. A processor is coupled to the communications module and processes the Ethernet packet. It removes the Ethernet header and adds Virtual Local Area Network (VLAN) tagging information to a padding section in the packet. In one aspect, the processor includes an encryption module that encrypts the VLAN tagging information along with the IP data. The network device includes a signal output through which the packet is transferred to a destination within the IP network over the communications channel as an IPSec tunnel.
