Bug ID 1021481: 'http-tunnel' and 'socks-tunnel' (which are internal interfaces) should be hidden.

Last Modified: May 29, 2024

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:
16.0.0,, 16.0.1,,, 16.1.0, 16.1.1

Fixed In:
17.0.0, 16.1.2

Opened: May 26, 2021

Severity: 3-Major


The Linux command 'ifconfig' or 'ip a' shows two devices 'http-tunnel' and 'socks-tunnel' that are for TMM internal use only.


As long as these devices are not used there is no impact aside from possibly causing confusion. Any attempt to use those devices from a host process fails or produces unpredictable results. These devices should not be exposed on the Linux host.


These interfaces show up regardless of the BIG-IP configuration.



Fix Information

The devices 'http-tunnel' and 'sock-tunnel' no longer show up on the Linux host.
