I just configured the apache2 server running on openSUSE 10.3 box and
could browse the html page through "http://localhost". But I can't
browse the page from other LAN (home network) machines. I could "ping"
the server box. I tried even telneting to the port 80, but it doesn't
connect.

Please help me to configure the apache server so that I could browse
the html page at least from other machines in the LAN.

Here is the port 80 information:

# netstat -an | grep "80"
tcp 0 0 :::80 :::*
LISTEN

(I don't know whether I need to change the firewall parameters, but I
made some changes the value in FW_SERVICES_INT_TCP, FW_FORWARD_MASQ
and FW_REDIRECT)
Here is my configuration in the /etc/sysconfig/SuSEfirewall2 (note
that the server machine internal IP addtess is 192.168.0.105):
