[<UDP local port>]
[<UDP mode>] In UDP transparent transmission, it has to be 0.
[<UDP mode>] 0 : destination peer entity of UDP will not
change.
[<UDP mode>] 1 : destination peer entity of UDP can change
once.
[<UDP mode>] 2 : destination peer entity of UDP is allowed to
change.
Note: [<UDP mode>] can only be used when [<UDP local port>] is
set.
[<TCP keep alive>]
[<TCP keep alive>] 0
[<TCP keep alive>] 1 ~ 7200
for UDP only
default 0. unit: 500 milliseconds.
: disable TCP keep-alive
