Description
A new CLI parameter was introduced in FortiOS v5.2.8 and v5.4.1:
config firewall policy
edit 0
set delay-tcp-npu-sessoin | enable/disable TCP NPU session delay in order to guarantee packet order of 3-way handshake.
end
This parameter included a spelling mistake of 'sessoin' (instead of session).
Solution
This parameter "delay-tcp-npu-sessoin" has a spelling mistake only in FortiOS v5.4. In FortiOS v5.2 and v5.6 the typo has been corrected.
For the firewall migrations from v5.2 to v5.4, 'delay-tcp-npu-sessoin' must be manually written in the firewall configuration to make it compatible with the supported syntax.
