Cannot ping the server's public ip from the outside world.

Hello:

Another newbie...

I have a Netware Small Business 6.5 server that I'm trying to setup. The
server has 2 network card (internal/external). 1 card is only binded to a
public ip 71.143.110.250/subnet 255.255.255.248 w/ a default route
71.143.110.254. The other one is disabled at this point.

In my DSL router I have 2 wire 170HG which is set to dhcp fixed public
network/bridge Network to allow public broadband ip to be used in the
network. The router picks up an ip from my isp through PPPOE picking up
71.143.110.254. The router address is 192.168.1.254 and running dhcp.
Throough the router I can allocate public ip to my dhcp assigned private ip.

I can ping the server's public ip from another computer in the network that
has an allocated public ip, but I couldn't ping it from the router or from
outside the internet although I can ping another worksation in the lan from
outside the internet. If I tracert it, the connection stops at the router
and does not continue to the server.

I'm 100% sure that I'm doing this wrong, but how am I able to ping the
server from the outside world. The router's is set to allow ping, echo,
etc... and the ip 71.143.110.250 has all ports open in the router.

What should be my best approach considering my server has 2 nic cards.

Btw, I'm binding the nic card to a public ip so I can setup gw to it.

Thanks!

Re: Cannot ping the server's public ip from the outside world.

Normally a public IP only sits on the router/firewall, and private IP's on
the server. You would not be able to ping the server from the outside to
any IP address behind the router. Unless your router is just the gateway
and all ports should be open and allowed. You should have a static IP on
the Public NIC on the server, and the next hop would be the router. You
should be able to ping both the router and the public NIC.

Personally, I just have our NSBS6.5 server running 2 NIC's, with the public
nic connected directly to the ADSL modem, and I run the Bordermanager 3.8 on
that server.

On the server, try to "unload ipflt" and see if it works. Could just be you
do not have any ports open including the ping port (ICMP).
