• A Web page that updates automatically. Some Web pages, e.g. home pages,
live images, update themselves automatically and can keep the line open.
Don't keep a window with such a page open while you are not using it.
External problems may be:
• You are talking to a MaxPro RWS-NT V1.0.0.4 router. That router recog-
nises "Echo Requests" as traffic and incorrectly keeps the line up. If you can
make sure that the router on the other end of the line is a MaxPro RWS-NT
V1.0.0.4, put the command "
PPP EchoRequest Off
" into the part of the con-
figuration file relating to that site.
• If it is another external problem, try contacting the owner of the router at the
other end of the line and make sure that the router does not send unsolicited
traffic. Try setting the timeout to a small value e.g. by adding the following
command to your configuration file: "
ISDN IdleCloseTime 10
".
5. I cannot connect to Telia with AutoConfiguration, why?
Telia is using the private A-class IP range
10.0.0.0
, which is a non-routable
subnet that is also used locally by the AutoConfiguration setup! To connect
anyway, you can manually change the generated configuration to use the pri-
vate B-class
192.168.0.0
subnet with SubnetMask
255.255.0.0
. Such a
configuration is given in the examples section of the Reference Manual on the
CD-ROM.
6. When I use the SecureWall function, sending mail is very
slow, why?
Some external mailers check the source port #113 to verify the identity of the
sender. Since the SecureWall drops unsolicited incoming packets, the mailer
will experience a timeout before giving up and accepting the mail anyway. If
you are in that case, you can simply map this port to the
Multi Com
, which will
signal that the port is not reachable and cause the mailer not to wait. To do so
add the following line to your configuration or chose the equivalent option in
the EasyConfig wizard:
IP Translation Map 113/tcp To <IP address of your MultiCom>
7. The SecureWall prevents some types of FTP connections.
As with most firewalls, FTP transfers can only succeed if the FTP program is
set to passive mode for gets and active mode for puts (these are standard in
Internet Explorer, Netscape, pftp, CuteFTP and Fetch in firewall mode).
8. Is the
Pocket Multi Com
Year 2000 compliant?
Yes. A declaration of conformity is available on our web-site.
