Note: uncommenting the last four options at default.vcl made no
difference.

cat /etc/default/varnish
# Configuration file for varnish
#
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES
and $MEMLOCK
# to be set from this shell script fragment.
#
# Should we start varnishd at boot? Set to "yes" to enable.
START=yes
# Maximum number of open files (for ulimit -n)
NFILES=131072
# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory. If you increase
log size,
# you need to increase this number as well

# Default varnish instance name is the local nodename. Can be
overridden with

# This file contains 4 alternatives, please use only one.
## Alternative 1, Minimal configuration, no VCL
#
# Listen on port 6081, administration on localhost:6082, and forward
to
# content server on localhost:8080. Use a 1GB fixed-size cache
file.
#
# DAEMON_OPTS="-a :6081 \

# -b localhost:8080 \
# -u varnish -g varnish \
# -S /etc/varnish/secret \
# -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
## Alternative 2, Configuration with VCL
#
# Listen on port 6081, administration on localhost:6082, and forward
to
# one content server selected by the vcl file, based on the request.
Use a 1GB
# fixed-size cache file.
#
DAEMON_OPTS="-a :80 \
-T 127.0.0.2:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s
file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
If you need any other info let me know. I am all out of clue as to whats
the problem.
