Sending e-mail is occasionally
slow when more than one
workstation is sending e-mail
to the same SMTP server.
A limitation of NAT, the SMTP
server uses a different port
number than the one requested
by the workstations sending
e-mail so the LAN Modem does
not know which of the 2 (or
more) workstations to fo rward
the response to. Therefore, the
request is discarded.
After 30 seconds, the SMTP
server responds, this time using
the port number specified by the
workstation allowing the e-mail
to be sent.
Co-ordinate the send ing of your e-mail with the other
workstations, or have each workstation use a different
SMTP mail server.
Compression does not work Compression is not configured. Go to the appropriate Service Provides page and ensure
compression is enable d.
Compression negotiation was not
successful. Although compression is enabled on the LAN Modem,
the device the LAN Modem is dialing into must also
have compression enabled and also support the same
type of compression (hi/fn LZS) otherwise compression
negotiation will not be successful.
