- Vendor Statements

Permitting TCP forwarding is the expected and known default configuration. If it is not desired, it can disabled using the AllowTcpForwarding option in the /etc/ssh/sshd_config configuration file. However, only disabling TCP forwarding does not improve security unless users are also denied shell access. For more information, see man sshd_config.
