UC-7101/7110/7112 Software User’s Manual Configuring UC-7101/7110/7112

Enabling NAT at Bootup

In most real world situations, you should use a simple shell script to enable NAT when the

UC-7101/7110/7112 boot up, as indicated by the following:

1. setting iptables

2. iptables-save > /home/xxx.file (xxx.file is the user defined file name)

3. vi /etc/rc

4. Append echo 1 > /proc/sys/net/ipv4/ip_forward

5. Append iptables-restore /home/xxx.file (xxx.file is the user defined file name)

Configuring Dial-in/Dial-out Service

Dial-out Service

Direct cable connection:

y Without username and password, use:

/>pppd connect ‘chat –v’ /dev/ttyM0 38400 crtscts&

With username and password, use:

/>pppd connect ‘chat –v’ user xxxxx password xxxxx /dev/ttyM0 38400 crtscts&

Connect Using a Modem:

y Use:

/>pppd connect ‘chat –v ATDT<phone_number> CONNECT’ user xxxxx password xxxxx

/dev/ttyM0 38400 crtscts&

ATTENTION

If dial out fails, the pppd connection will be blocked, and the users will need to shut down pppd,

and re-dial. Since the return value is always OK (regardless of whether or not the connection is

blocked), the API must be set up to check the network status to determine if the connection is

complete.

Dial-in Service

Direct cable connection:

y Use either of the following:

/>pppd <Local_IP_Address>:<Remote_IP_Address> /dev/ttyM1 38400 local crtscts

/>pppd <Local_IP_Address>:<Remote_IP_Address> /dev/ttyM0 38400 local crtscts login

auth

Connect Using a Modem:

y Use:

/>pppd connect ‘chat –v AT CONNECT’ <local_IP_Address>:<Remote_IP_Address>

/dev/ttyM0 38400 crtscts login auth
