Internet access problems

[Jebecca]

Hi all,
This learning curve is a lot steeper than I expected. It's been almost three weeks now that I have been trying to get things setup but I still don't have internet access. The system is as follows,
bare metal installation of Opnsense on a HP Elitedesk 800 G3 with a HP NC365T 4 port Ethernet adapter giving a total of five interfaces, em0 WAN, ibg1 LAN, igb2 MGMT, igb0 & 3 SPARE. At present the spare interfaces have not been enable but may be assigned to LAGG in the future. The Vlans have igb2 as their parent and are vlan 10 TRUSTED, vlan 20 IOT, vlan 30 GUESTS, vlan 40 SECURITY, vlan 50 DMZ, vlan 60 STORAGE, vlan 99 MGMT. The same vlans are setup in a Cisco 3750G switch. There is a second HP Elitedesk 800 G4 with a bare metal installation of Proxmox but at the moment I have left it turned off. When I check the Firewall/Log Files/Live View all the entries are green, but they are all Interface WAN Out UDP. Would this indicate that the Internet access problem is not being caused by OPNsense?

Can you provide more information in what does not work? How is OPNsense connected to the internet? Can you access the internet from OPNsense itself? Where do you connect a clients to, LAN, one of the VLANs? Does the client get an IP? What are you using for DHCP and DNS on OPNsense?

Hi patient0,
            thanks for the questions, hope I have provided the information requested. If not please let me know.
* OPNsense connection to Internet - WAN port(em0 Interface) is connected to a Nokia Fastmile 5G Gateway set to Bridge mode.
* Internet access from OPNsense - Not sure, I was basing my No Internet access on my laptop taskbar icon showing No Internet Access. How would I check for access from OPNsense?
* Where do you connect a client to - All clients are connected to a 24+4 Cisco Catalyst 3750G managed switch. Ports have been assigned to Vlans and the devices connected according to there use, My laptop - TRUSTED vlan, NVR - SECURITY vlan, Wireless access point - MGMT vlan.
* Does the client get an IP - WAN is set to DHCP due to ISP changing the IP on modem restart, which happen more than I would like due to temperamental power supply. Next investment is a UPC.
* What are you using for DHCP and DNS on OPNsense - ISC DHCPv4 Server and Dnsmasq DNS/DHCP are running. I'm trying to setup OPENdns but I keep getting badauth when I run the test.

The problem I have now is that if I move my laptop from port 5 Vlan-TRUSTED to port 23 Vlan-MGMT_VLAN the Internet is working. So I'm looking at InterVlan routing between TRUSTED and MGMT_VLAN but I'm not sure if this is the right thing to do. From what I've read the MGMT_VLAN doesn't need internet access.

ISC DHCPv4 Server and Dnsmasq DNS/DHCP are running.

AFAIK you can not run those at the same time ?!
