24.1 Legacy Series / Re: Opnsense requires reboot after WAN goes down

« on: June 18, 2024, 09:24:30 am »

Update - my WAN went down again this morning.

I tried disconnecting and reconnecting the ethernet cable - the internet did not come back up.

I don't have a reload button on Interfaces>Overview>WAN - so I couldn't try this method.

Lastly, I tried running `ifconfig em4 down` and `ifconfig em4 up` and that did bring it back up, thankfully without a reboot.

@franco - does that help to identify what's going wrong at all? Is my only option to run a script that will run  `ifconfig em4 down` and `ifconfig em4 up` when it notices a problem?

Thanks in advance!

My internet is down right now, but I don’t see a reload button under Interfaces > Overview. I know there are some UI issues on mobile, so may be because of that?

Thanks for the links @canadidan

I run OPNsense as a virtual machine under Proxmox. Because the VM is connected to a bridge interface, OPNsense cannot tell if the physical link goes down between the modem and the server NIC. You didn't mention if you use a VM or not, but this is my hypothesis about why this happens to me. I suspect the physical link must drop briefly, and the modem refuses to provide WAN access until the router requests a new lease over DHCP.

For me, opnsense is running on bare metal - I could have done it on a VM, but seeing as it the one thing giving me internet access I wanted it to be as simple as possible.

If I go into Interfaces>Overview>WAN and click Reload, the WAN link comes back every time. This is more or less what Franco said to try below. A reboot will also accomplishes this.

I will try this next time for sure. If it works, perhaps I'll have to look at using one of the scripts!

Got it, thank you for the time.

I'll have to wait until it goes down again, unless there's any merit to fabricating the scenario by switching the ISP router off/on?

Ah I see ok. Do you mean do that when the WAN connection goes down, or try it when it isn’t a problem to see if it comes back up?

Hey franco, thanks for helping!

Does it come back when you unplug and plug the cable?

The cable of the opnsense router? Yes - once the WAN comes back up, rebooting opnsense fixes the problem. I am hoping there's a way to fix it without needing to reboot.

Does it come back when you set

I can definitely try this the next time the WAN goes down. Thankfully it doesn't happen _that_ often.

> Also it would be good to know your setup, do you have a modem in front of the firewall for instance.

I also forgot to answer this,

Yeah, unfortunately I have to have the ISP router in front of opnsense. The ISP router is in modem mode, though.

> The only problem I can imagine you have is a not well supported NIC for WAN interface, like realtek ones.

It is a intel NIC

Ah I just checked the WAN Gateway settings:

Disabled: unchecked
Name: WAN_Gateway
Description: blank
Interface: WAN
Address Family: IPv4
IP Address: <my gateway IP>
Upstream Gateway: checked
Far Gateway: unchecked
Disable Gateway Monitoring: checked
Disable Host Route: unchecked
Monitor IP: blank
Mark Gateway as Down: unchecked
Priority: 255


Is it because Gateway Monitoring is disabled?

Thanks for the reply, cookiemonster.

> Please check for messages in dmesg.

I checked the `Audit`, `Backend`, `Boot`, and `General` log sections and the only thing that I could see that seemed related was this log (there are a lot of them around the time the internet dropped):

```
action rfc2136.reload.wan not found for user root
```

> OPN has a service that you'll find on the dashboard: "dpinger" and that is the Gateway monitor (WAN_DHCP).

I searched and looked for "dpinger" on the dashboard, but it doesn't show. I don't even see it as a plugin or a service. Not sure what I'm missing.

> Interfaces > WAN: what settings do you have there?

Enable: checked

Am I allowed to bump this post after a few days?

Appreciate any help.

24.1 Legacy Series / Opnsense requires reboot after WAN goes down

« on: June 07, 2024, 03:06:08 pm »

Afternoon everybody,

Occasionally my ISP will have a problem and the WAN will drop out. When it comes back online, opnsense doesn't seem to automatically pick it back up and requires a reboot.

I've seen similar questions suggesting to set certain DHCP setttings on the WAN interface, but I am using a static IP so am in a different situation.

Is there a setting to allow it to try and re-establish connection, or is a reboot the only way to solve this?
