Hello everyone,
I'm having some trouble with my OPNSense 22.7 setup and need assistance. I've tried troubleshooting on my own but I'm a networking novice and can't spend long hours on it due to living with others. (To be fair, if you have any advice on how to troubleshoot without interrupting others, that'd be great too.)
Setup:
- Fibre connection with ISP router (not in bridge mode yet)
- Small form factor PC with OPNSense 22.7 (ports labeled WAN and LAN)
- Connections:
- ISP LAN to OPNSense WAN
- OPNSense LAN to Network Switch
- Network Switch to Patch Panel
- Patch Panel to Macbook Pro via Ethernet with Thunderbolt adapter
- Reset OPNSense to default settings, powered off, rebooted, and skipped installation wizard
DHCP Settings:
- IP range: 192.168.1.50 - 192.168.1.254 (extended from default)
- DNS Servers: 1.1.1.1, 1.0.0.1
- Settings: Saved and applied
- Test machine: Macbook Pro (Ethernet via network switch and patch panel)
- DNS Server: 192.168.1.1 (auto-set)
Problem:
- Cannot access websites (e.g., https://forum.opnsense.org/); receiving Chrome DNS error: "DNS_PROBE_STARTED"
Any suggestions on what I might be missing? Thanks in advance!
Any denies for DNS traffic to 1.1.1.1 in your logs? Remember to allow both UDP and TCP 53
Does ping to 8.8.8.8 work? Perhaps your ISP router doesn't have a route back to your LAN subnet? Test from the firewall and from the LAN
