Title: [SOLVED] DHCP-WAN=internet OK and STATIC-WAN=no internet
Post by: gruutch1 on July 30, 2016, 01:22:48 pm

Hello!

Iam a newbie with OpnSense. My Firewall experience was as yet with Ipcop. It is a linux based firewall.

Today I installed OpnSense 16.7-amd64 with two network cards (WAN and LAN).

This is my test environment:
Provider (Fritzbox/Gateway) -------WAN-OpnSense-LAN--------CLIENTS

The IPs are:
Fritzbox  (Gateway)  = 192.168.1.1 (Static)
WAN OpnSense        = 192.168.1.11 (DHCP from Fritzbox)
LAN OpnSense          = 192.168.0.1 (Static)
Clients get IPs from DHCP-range 192.168.0.10 < 192.168.0.250

After this installation, I can go the internet. Perfect!
But if I change the WAN-OpnSense IP from DHCP to static (in 192.168.1.250), then I have no Internet.

I think I must entry the DNS and Gateway IP manually. But I see so many settings and I couldn´t find the settings for this two IPs. I was unsure and I tried something, but it didn´t worked.

Could you tell me please, where I type the rest settings exactly in OpnSense?

Some things to consider:

- the default gateway is at IPv4 upstream gateway on the WAN page. Test your connection independently from DNS by pinging 8.8.8.8.

- The Fritzbox needs to know where your internal LAN is. That means that you need to add a static route for 192.168.0.0/24 to go via your OPNsense WAN interface.

- The OPNsense WAN interface blocks private networks (RFC1918) by default.

- Inbound connections are firewalled twice; on the Fritzbox and on OPNsense.

- You may be able to set your Fritzbox in bridged mode and make the PPPoE connection from OPNsense.

Hello Bartjsmit,

thank you for your answer.
But in my imagination it is illogical, why I should change my fritzbox static route and / or set to bridging-mode.
I say that, because back then I used the linux-firewall ipcop. And there I didin´t changed the fritzbox settings.
At ipcop I installed two networkcards too and setting up the same settings like in opnsense and it did worked.

Hi gruutch,

I understood that you are talking about outgoing traffic, ie open Google with a browser.

So, for a static config you have to enter gateway and dns manually (booth the LAN IP of your Fritzbox). Have a look at the wizzard somewhere in the menus. I think this will lead you through the complete setup.

Hope this helps
Uwe

Hello wurmloch, hello bartjsmit

ok I started the wizard again. And suddenly it works.
I suppose, that my gateway settings, which I made yesterday was wrong.
But now it works.

Thanks to both of you for your help!
