Using the command-line interface
Parameter Description
-l Listening port. Allows the user to set a new TCP port number to listen on rather
than the default value of 4000+ASY port #.
-m Multihome additional consecutive addresses index
-ok Open socket in quiet mode, so that there is no OK response to the TCPPERM
command.
-s Source port number
-ssl Use SSL mode
-t Use Telnet mode. Opens socket in the corresponding Telnet mode (port 23 default),
0=raw, 1=Telnet Mode, 2=Telnet Mode with null stuffing. If this is not specified, the
router uses the mode specified for the associated ASY port in general setup. The -t
option sets use of the ok option always.
Use the tcpperm command to execute automatically on power-up by using the cmd n autocmd
'cmd' macro command. For example:
cm d 0 aut ocm d ' t cpper m asy 0 192. 168. 0. 1 - f 3 - s3000 - k10 - e1'
Considerations for use with VPN or GRE tunnels
When the socket being used by TCPPERM is opened, the default behavior is to use the address of the
interface over which the socket is carried (ETHn or PPPn) as the source address of the socket. If the
socket data is to be tunneled, you may need to use -en modifier so the source address of the socket
matches the local subnet address specified in the appropriate eroute. You can also set this behavior in
the web interface on the Configuration > Network > Advanced Network Settings page by setting
the parameter Default source IP address interface: Ethernet n.
