General Discussion / Re: No internet access - not Getting IP for WAN via DHCP

« on: November 30, 2023, 01:15:15 am »

Thank you for your response. This evening I have connected from the LAN port on the ISP router instead of the WAN port as you suggested.

Are you sure that the correct WAN port of your OpnSense is connected to bridge?

When I booted the OPNsense router the loading console showed that igc0 and igc1 were UP. To ensure that these corresponded to ETH0 and ETH1 as labelled on the device, I went through the interface setup again but this time I disconnected both WAN and LAN connections to the OPNsense router and used the auto detect function, plugged in the WAN cable to ETH0 and it detected this as igc0. Then I plugged in the LAN cable into ETH1 and it detected this as igc1, so this is how I had it configured before and I believe this is all correct.

I rebooted both ISP router and OPNsense router just in case it required this. After rebooting I noticed that during the console configuration stage, many of the other configuration steps (e.g firewall, Lagg, VLAN, LAN etc etc) said done very quickly but when it got to the configuring WAN, it took about 25 seconds before it said ....Done. Is that normal behavior?

Once at the login in the console, I noticed the WAN IP is still showing as V4:DCHPv4 0.0.0.0/8

Do you see that only on the console or can you access the web GUI from your PC?

I was able to access the web GUI at 192.168.1.1 and login (both yesterday and today). The IP shown in the web GUI for WAN also (still) shows 0.0.0.0 for WAN. I have attached some snips of some web GUI sections (filenames named accordingly).

I'm obviously missing something. Any ideas?

Many Thanks

General Discussion / No internet access - not Getting IP for WAN via DHCP

Hi all,

I've switched my ISP's [modem/router/ap] into bridge mode and have connected a cable from the WAN port on the back to the first port on my OPNsense router. The ports on the OPNsense router are labelled ETH0,ETH1,ETH2,ETH3. When installing OPNsense I configured the ports - the available options in the list were igc0,igc1,igc2,igc3 so I set WAN as igc0 and LAN as igc1. So... WAN from bridged ISP router into WAN (igc0/ETH0).

I've connected my PC into the LAN port and am able to access the OPNsense GUI where I have run through the wizard and have set WAN as DHCP and have specified DNS servers as 9.9.9.9 and alternative as 1.1.1.1. I have left the two checkmarks on (for the blocking of bogon and the other one).

From the video's I've seen, I should be able to access the internet off the bat but I can't. I've rebooted both the ISP modem and the OPNsense router. When the OPNsense router has finished booting it shows my LAN IP as 192.168.1.1/24 but for the WAN IP it shows 0.0.0.0/8 and I assume this is why I can't access the internet.

I went into the ISP routers GUI, but most of the configurable settings have been disabled due to being in bridge mode. I've also tried fiddling about with the TCP/IPv4 properties for the network interface on my PC, but to no avail.

The cables I've used are straight thru patch cables RJ45 pinout T-568B and have tried several which haven't worked, so I don't think the cables are the issue. I do not yet have a managed network switch, I've plugged my PC directly to the LAN port on the OPNsense router, does that matter?

Any tips on what I could try get a WAN IP detected by OPNsense from my ISP's router in bridge mode please?
Also please bear in mind that I'm a networking beginner so simple explanations would be helpful.

Many Thanks!

While I'm here, do you have any tips on what to read / watch / research to get me up and running as fast as possible as an average home OPNsense user (generally unfamiliar with networking terms and practices etc)?

Many Thanks!

Ok thank you.

Looks like I may be having some late nights for the next few days / weeks then! I'll start work after the wife goes to bed

General Discussion / Configuring OPNsense without using router bridge mode?

« on: November 28, 2023, 05:29:54 pm »

Hi All,

It's my first post here. I've just installed OPNsense for the first time and switched my ISP's router into bridge mode which allowed me to access the config pages from my browser.

I soon got a shout up the stairs from my wife saying "the internets not working!".

Am I able to familiarise myself with the interface and configure some settings without using my ISP's router in bridge mode so the rest of the family can still use the current network configuration?

Can I connect a lead from my ISP routers WAN port and connect it to my firewall device and still access OPNsense when my ISP's router is not in bridge mode?

EDIT: also, if this is possible, how much configuration can I do like this ?

Many Thanks
