3Com OfficeConnect 3C886A Release Note page 11

10 Under Private Network Parameters, specify your private network parameters.
Private Network IP Address: Enter the IP address of the server LAN Modem.
For example, if the server LAN Modem has been designated as Site A, or is
set to its default IP address, enter 192.168.1.1.
Private Network Subnet Mask: Enter the subnet mask of the LAN Modem
you are dialing into. If you are not sure, leave the default (255.255.255.0).
Domain Name: Enter the domain name of the server LAN Modem, if
applicable. This field may be left blank if you have entered a Private
Network IP Address. If you want to access client LAN resources via domain
name (that is, "my_net.com") enter an appropriate domain name.
11 Specify Callback parameters if you want to use this feature. Otherwise, leave the
defaults.
Enable Callback: Choose to enable or disable Callback. By default Callback
is disabled.
Callback Delay: Callback Delay is the amount of time the server will wait
before calling back the client. By default this field is set to 5 seconds.
Callback Timeout: Callback Timeout is the amount of time that the client
waits for the server to call back. Note that this value is in addition to the Call
Back Delay value. By default this field is set to 90 seconds.
Callback Number: Enter the number that the remote site will call back when
the LAN Modem connects to the remote server. This allows for the reversing
of toll charges for the dial-in call. Note that if a different number is
configured on the server, the server callback number takes precedence.
Callback Username and Password: Enter the username and password of the
callback user. These values are used to verify the server's authenticity to the
client. These fields should match the login and password fields on the server
LAN Modem's dial-in user parameters. Note that callback authentication is
optional.
12 Under Miscellaneous, Do you want to use this Private Network to access the
Internet: Set this field to No. Since this service provider will be used to dial into
another 56K LAN Modem, a second phone line is not available on the remote LAN
Modem in which to launch a call to an Internet Service Provider.
13 Under Miscellaneous, indicate whether or not you would like to use data
compression when transferring data by selecting the appropriate radio button.
14 Under Miscellaneous, leave the default, NAT enabled, if the dial-in user will be
accessing the remote LAN Modem via the Single-User scenario. For LAN Modem
Site-to-Site dial-in, set this field to None, as the Site-to-Site scenario does not use
NAT.
15 Under WAN Link IP address, leave these fields blank. The LAN Modem will
automatically assign these values upon connection.
16 Under Subnet Mask, leave these fields blank. The LAN Modem will automatically
assign these values upon connection.
17 For Allow Automatic Call Initiation, leave the default setting which is Yes. This will
allow you to automatically place a call by entering the IP address of a device on the
remote LAN.
