# ADSL user name.  You may have to supply "@provider.com"  Sympatico
# users in Canada do need to include "@sympatico.ca"

### ONLY TOUCH THE FOLLOWING SETTINGS IF YOU'RE AN EXPERT

# How long adsl-start waits for a new PPP interface to appear before
# concluding something went wrong.  If you use 0, then adsl-start
# exits immediately with a successful status and does not wait for the
# link to come up.  Time is in seconds.
#
# WARNING WARNING WARNING:
#
# If you are using rp-pppoe on a physically-inaccessible host, set
# CONNECT_TIMEOUT to 0.  This makes SURE that the machine keeps trying
# to connect forever after adsl-start is called.  Otherwise, it will
# give out after CONNECT_TIMEOUT seconds and will not attempt to
# connect again, making it impossible to reach.
CONNECT_TIMEOUT=60

# How often in seconds adsl-start polls to check if link is up
CONNECT_POLL=6

# Character to echo at each poll.  Use PING="" if you don't want
# anything echoed
PING="."

# File where pppoe writes its process-ID
PIDFILE=/var/run/$CF_BASE-adsl.pid

# File which tells adsl-connect to terminate connection
TERMINATEFILE=/var/run/pppoe.stop

# Do you want to use synchronous PPP?  "yes" or "no".  "yes" is much
# easier on CPU usage, but may not work for you.  It is safer to use
# "no", but you may want to experiment with "yes".
# NOTE: It seems that using synchronous PPP causes a kernel panic under
# Linux 2.2.14.  It is therefore NOT RECOMMENDED.
SYNCHRONOUS=no

# Do you want to clamp the MSS?  Here's how to decide:
# - If you have only a SINGLE computer connected to the ADSL modem, choose
#   "no".
# - If you have a computer acting as a gateway for a LAN, choose "1412".
#   The setting of 1412 is safe for either setup, but uses slightly more
#   CPU power.
CLAMPMSS=1412
#CLAMPMSS=no

# LCP echo interval and failure count.
LCP_INTERVAL=20
LCP_FAILURE=3

# PPPOE_TIMEOUT should be about 4*LCP_INTERVAL
PPPOE_TIMEOUT=80

# Firewalling: One of NONE, STANDALONE or MASQUERADE
