ISDN_CIRC_x_FRAMECOMP (EXPERIMENTAL) This parameter is only used if
OPT_ISDN_COMP is set to ’yes’. It handles frame compression.
The following values are possible:
’no’ no frame compression
’default’ LZS according to RFC1974(std) and BSDCOMP 12
’all’ Negotiate lzs and bsdcomp
’lzs’ Negotiate lzs only
’lzsstd’ LZS according to RFC1974 Standard Mode (“Sequential Mode”)
’lzsext’ LZS according to RFC1974 Extended Mode
’bsdcomp’ Negotiate bsdcomp only
’lzsstd-mh’ LZS Multihistory according to RFC1974 Standard Mode (“Sequential Mode“)
You have to find out by yourself which value is supported by the provider. T-Online
supports only ’lzsext’ as far as I know. With most other providers ’default’ should work.
Attention: using channel bundeling together with ’lzsext’ can lead to problems specific
to the dial-in server and provider. As providers use different types of dial-in servers there
can be differences between dial-in servers of the same provider.
’lzsstd-mh’ is meant for router-to-router usage (r2r). It is not used by providers but
using it between two fli4l routers leads to significant improvements while transferring
more files in parallel. Header compression is needed here and therefore will be activated
automatically.
ISDN_CIRC_x_REMOTENAME This variable normally is only relevant when configuring
fli4l as a dial-in router. Set the name of a remote hosts if you want but this is not needed.
Default setting: ISDN_CIRC_x_REMOTENAME=”
ISDN_CIRC_x_PASS Enter provider data here. In the example data for Microsoft Network
is used.
ISDN_CIRC_x_USER holds the user-id, ISDN_CIRC_x_PASS the password.
Note for T-Online:
Username AAAAAAAAAAAATTTTTT#MMMM is composed from a 12 digit ’An-
schlußkennung’ plus T-Online-Number and ’Mitbenutzernummer’. Put a ’#’ after the
T-Online-Nummer if it is shorter than 12 characters.
In rare cases another ’#’ character has to be inserted between ’Anschlußkennung’ and
T-Online-Number.
For T-Online-Numbers with 12 characters no additional ’#’ is needed.
Example: ISDN_CIRC_1_USER=’123456#123’
For Raw-IP circuits this variable has no meaning.
ISDN_CIRC_x_ROUTE_N Number of routes of this ISDN circuit. If the circuit defines a
default route you must set this to ’1’.
ISDN_CIRC_x_ROUTE_X Route(s) for this circuit. For Internet access the first entry
should be ’0.0.0.0/0’ (default route). Format is always ’network/netmaskbits’. A host
route for example would look like this: ’192.168.199.1/32’. If dialing in to company or
university routers name only the net you want to reach there. Examples:
