ENC(4) - Device Drivers Manual # ENC(4) - Device Drivers Manual NAME # enc - encapsulating interface SYNOPSIS # pseudo-device enc DESCRIPTION # The enc interface is a virtual interface for ipsec(4) traffic. It allows packet filtering using pf(4); prior to encapsulation and after decapsulation, packets may be monitored using tcpdump(8). An enc interface can be created at runtime using the ifconfig enc‌N create command or by setting up a hostname. ...
IKED.CONF(5) - File Formats Manual # IKED.CONF(5) - File Formats Manual NAME # iked.conf - IKEv2 configuration file DESCRIPTION # iked.conf is the configuration file for iked(8), the Internet Key Exchange version 2 (IKEv2) daemon for IPsec. IPsec itself is a pair of protocols: Encapsulating Security Payload (ESP), which provides integrity and confidentiality; and Authentication Header (AH), which provides integrity. The IPsec protocol itself is described in ipsec(4). In its most basic form, a flow is established between hosts and/or networks, and then Security Associations (SA) are established, which detail how the desired protection will be achieved. ...
IPCOMP(4) - Device Drivers Manual # IPCOMP(4) - Device Drivers Manual NAME # ipcomp - IP Payload Compression Protocol DESCRIPTION # IPComp is enabled with the following sysctl(2) variable in /etc/sysctl.conf: net.inet.ipcomp.enable IPComp is a protocol used to reduce the size of IP datagrams. It can be used to enhance the communication performance between a pair of hosts/gateways, especially on slow links, by compressing the datagrams, provided the communicating entities have enough computational power. ...

IPSEC(4) - Device Drivers Manual # IPSEC(4) - Device Drivers Manual NAME # ipsec - IP Security Protocol DESCRIPTION # IPsec is a pair of protocols, Encapsulating Security Payload (ESP) and Authentication Header (AH), which provide security services for IP datagrams. Both protocols may be enabled or disabled using the following sysctl(2) variables in /etc/sysctl.conf. By default, both protocols are enabled: net.inet.esp.enable Enable the ESP IPsec protocol net.inet.ah.enable Enable the AH IPsec protocol ...
