IP Networking

I cannot ping the openbsd gateway for laptop and desktop as well but can get address.
I have nat working as below:
ext_add=60.48.0.0/32 priv_add=192.168.2.0/24 priv_adds=176.16.10.0/24
nat on $ext_if inet from $priv_add to any -> $ext_add or $ext_if
nat on $ext_if inet from $priv_adds to any -> $ext_add
Wired Connection INformation from windows:
IP add: 176.16.10.10 Default Gateway:176.16.10.1 DHCP Server:176.16.10.1(Interface address)
I cannot ping the 176.16.10.1 requst tme out.

So NAT is working on your openbsd box?

Do your laptop and desktop see your openbsd as their gateway?

My ADSL router does NAT so I've never needed to set it up.

What is the "ext_add" refering to? Who set that up, what is it supposed to mean?

I cannot 100% confirm that the nat is working correctly but at least no error message from log file. This rule is set it by me.
Laptop and desktop's gateway is openbsd box. I try to disable wireless and see if that working but still no luck.
Latest configuration : /etc/hostname.rl1 inet 176.16.10.1 option routers 176.16.10.1;
/etc/hostname.ral0 : 192.168.2.1 option routers 192.168.2.1;
I really need your help.

AFter changed the dhcpd.conf, desktop -> openbsd gateway(ok) openbsd -> desktop address(176.16.10.10) Not ok.
What wrong with it ?

NAT? Tunneling?

This seems way to difficult to configure for someone who has no experience with TCP/IP.

I don't think you are going to get this working until you simplify your configuration and learn to network one-step-at-time, starting very simple.

In other words, you do not have the experience to use BSD as a gateway in this configuration.

My advise is to contact your ISP and have them help you set up your gateway.

How to simplify this configuration ? I really don't know / Canu help me in this topic. Thanks. I can spend you a beer.

Contact your ISP and have them set up your gateway for you.
