Title: Strange behaviour with fresh install of OPNSense, R86S and SFP+
Post by: mikael1985 on March 18, 2024, 04:12:10 PM
Hello!

I am trying to replace the router sent from my ISP with a custom OPNSense router with R86S hardware. My internet connection is fiber 10 Gbps. I have successfully installed OPNSense, latest version.

I have added a text file /boot/loader.conf.local with contents "mlx4en_load="YES"" and assigned the different SFP+ ports as WAN and another for LAN. The LAN goes to a 10 Gbps switch.

After running the wizard in OPNSense and entering DNS servers of 8.8.8.8 and 1.1.1.1, I can only visit some pages but most of the Internet is not working at all. What could be the issue here?


This works:
Google works fine i browser

Opnsense.org works fine. I can also update OPNSense through the web gui

fast.com and fast cli speed test works fine

What does not work;
Everything else. Everything I try with "ping" fails, both from my Macbook Pro and from the OPNSense Web GUI.

Did you check the box to use the router as a DNS server? I'm guessing you can ping all kinds of IP, just not by name which points to a DNS issues of some kind (It's always DNS).

I can not ping any IP address. I tried "ping 1.1.1.1" and "ping 8.8.8.8" for instance.

I have not checked any checkbox to use router as DNS server what I can remember. Is that checkbox the "use system nameservers" in query forwarding (your screenshot)?

If you can't ping an ip, then something else is wrong.

I'm using an R86S in the exact same config as you with a 10G WAN SFP+ and the other as a 10G LAN SFP+, and I use one of the 2.5G RJ45 as a management port.

I know it doesn't really help you, but I have no issues whatsoever with mine.

Hi,

may I suggest you have not permitted ICMP.
Check if you have a rule
    Action: Pass
    Protocol: ICMP
    ICMP subtypes: Echo request
    Source: any
    Destination: WAN
    Description: Allow ping on WAN

I had similar problem on a different platform but same solution

I haven't touched the rules, but I'll give it a try.

Good to know that it works for you! Did you also add the loader.conf.local in /boot directory?

Yes indeed.

Would it be possible for you to share your OPNSense configuration somehow? E.g. which SFP+ port is your WAN/LAN. Nothing sensitive of course!
