Details
Check Text (C-216140r959010_chk)
Determine if TCP reverse IP source routing is disabled.
# ipadm show-prop -p _rev_src_routes -co current tcp
If the output of this command is not "0", this is a finding.
Fix Text (F-17376r372803_fix)
The Network Management profile is required.
Disable reverse source routing.
# pfexec ipadm set-prop -p _rev_src_routes=0 tcp
