No internet connection with IP Public as WAN

[Juicestyle]

Hello,

I'm trying to configure my WAN interface with a public IP address.
I've successfully configured my public IP on my WAN interface and set up my gateway.


However, when I connect to the LAN, I can't get out.

Do I need to configure SNAT?

Have a gode day

Yes you need Outbound NAT.

When you have automatic or Hybrid NAT rules following is the behavior:

A. When you use DHCP on your WAN, those NAT rules are created automatically.
B. When you set a Static IP on your WAN, but dont specify a GW on the Interface the NAT is not automatically created
C. When you set Static IP on your WAN, and specify GW on the Interface the NAT is automatically created.

OK, I create outbout rule:

From that picture, you already had auto rules created for all your LAN interfaces. So NATing should work from LAN > WAN. You dont need a manual NAT rule in this case and also the one you created is missconfigured.

Try to do some further checks from a LAN device like:

Code: [Select]

nslookup google.com

Code: [Select]

ping google.com

Code: [Select]

tracert google.com - Windows device

Code: [Select]

traceroute google.com - Linux device

Also how are your Rules set on the LAN e.g network from which is not working for you?
