# l2tp-client > RouterOS directory reference for /interface/l2tp-client. ----------- ## interface/l2tp-client **Type:** Directory Whether an item is disabled. Whether the interface is running. Descriptive name of the interface. Maximum Transmission Unit. Maximum packet size that the L2TP interface can send without packet fragmentation. Maximum Receive Unit. Maximum packet size that the L2TP interface can receive without packet fragmentation. Maximum packet size that can be received on the link. If a packet is bigger than tunnel MTU, it is split into multiple packets, allowing full-size IP or Ethernet packets to be sent over the tunnel. Remote address of the L2TP server. If the address is in the VRF table, VRF should be specified, for example, `192.168.88.1@vrf1` . User name used for authentication. Password used for authentication. Specifies which PPP profile configuration is used when establishing the tunnel. Keepalive timeout in seconds. Source address used for the L2TP connection. Whether to use DNS settings from the peer. When this option is enabled, dynamic IPSec peer configuration and policy (transport mode) is added to encapsulate the L2TP connection into an IPSec tunnel. Multiple L2tp/ipsec clients behind the same NAT will not work in this mode. To achieve such a scenario, disable use-ipsec and set static policies for clients with enabled tunnel=yes, level=unique settings. IPsec pre-shared key. Whether to allow FastPath processing. Must be disabled if IPsec is used. Whether to add the L2TP remote address as a default route. Distance value applied to the auto-created default route when add-default-route is enabled. Connects to the L2TP server only when outbound traffic is generated. If enabled, a route with a gateway address from 10.112.112.0/24 network is added while the connection is not established. Allowed authentication methods. Whether to randomize the source port for L2TP connections. L2TP protocol version to use. L2TPv3 circuit identifier. L2TPv3 cookie length. L2TPv3 digest hash algorithm.
