The loopback address is always  It's not supposed to change.
lo0 is "virtual" network adapter that always points back to itself, hence
the name "loopback".  That IP is reserved specifically for that purpose.

Configure your actual network adapter.  Do you have an ethernet card?  If
so, look at the output of 'ifconfig'.  The adapter that mentions "Ethernet"
in the media line is the driver you want to config.

I don't have a terribly educated answer to this, except point-to-point
adapters never seem able to ping both ends.  That's normal.  If you can
ping the far end from this machine and this machine from the far end, then
you're in good shape.
You may have to manually add a route for sl0.  Check the output of
'netstat -rn' to see if there's a route, and add it with 'route add' if
