# If your ISP assigns you an (dynamic) different IP address each time
# you log in, then use the following statement. If your ISP issued you
# a (static never changes) IP address to use every time you log in, then
# comment out the next statement and uncomment the statements following it.

# Get dynamic IP address from ISP if that's how they do it.
  set ifaddr 0.0.0.0/0  0.0.0.0/0  0.0.0.0  0.0.0.0


# Use static IP address from ISP if that's how they do it.
# Set static IP address your ISP assigned to you.
# s.s.s.s = your static IP address

# set ifaddr s.s.s.s 0.0.0.0/0 0.0.0.0 0.0.0.0
