accessing solaris 8 over WAN

We can access our solaris 8 from our LAN . However when we try to
access the same over our WAN , it is not able to ping the server .

/etc/hosts has entries for our DNS server. Another thing all WAN clients
are Windows 2000 workstations .

Here is the output netstat -nr
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ------ ---------

127.0.0.1 127.0.0.1 UH 271504175 lo0

Wan workstations have IP addresses 192.168.0.0

What should I do to enable WAN users access solaris 8 .

The first thing you should do is look at this - note # 4 and 5. Then check your other thread.
