adjust interface names to match your system (e.g. em0 to igc0

Despite your instructions, I missed changing one of the interface names and struggled for a while to make it work.

Big thanks for this.  I had not seen this mentioned anywhere else in my searches.

Don't you have to set the FiOS router into bridge mode or similar in its web page?

Thanks for the reply.  I don't have any FiOS equipment (other than the ONT), but perhaps this will help someone who finds this later and does.

While OPNsense has the necessary dhcp6c code path to allow your FiOS WAN interface IPv6 configuration to have both a link local (fe80:: prefix) and a global IPv6 address, it will not configure it that way by default (as of OPNsense 26.1.4 in March 2026).

You will need to also configure a custom dhcp6c client configuration file in [Interfaces->WAN->DHCPv6 Client Configuration, then select Override Configuration Mode] 

Thanks for this.  It has gotten me closer to getting a global address from FiOS, but I still don't receive it.  The only log entry that appears to be related is a series of these which I had not seen before:

Sending Solicit on igb0


They have been occuring at ever increasing intervals (20 secs, 30 secs, 1 min., 5 min., etc.)

Any hints as to what might be going on or where to check for more details?

Incomplete setup.  Needed Unbound DNS query forwarding for Internal addresses.

https://docs.opnsense.org/manual/dnsmasq.html#dhcpv4-with-dns-registration

The FQDN do not show in the /var/db/dnsmasq.leases, but they can be found with a nslookup.

Part of this was mentioned in the 25.1 Series but wasn't answered. @IsaacFL https://forum.opnsense.org/index.php?topic=47963.0


In Dnsmasq, the static mappings are set in hosts tab and are present in the /var/etc/dnsmasq-hosts, but they dont show the FQDN in /var/db/dnsmasq.leases and won't do an internal lookup successfully.

In Unbound, the "Register DHCP Static Mappings" option is checked

I am finding the forum comments and documentation a bit confusing on this. 

• I have some items in the hosts list without the host name or domain and others with the host name and domain (as a test). The entries without a name or domain pick up the device name, but not the domain for the leases. The others show the host name but nothing in the domain
• I have DHCP ranges with the domain defined (xyz.internal, abc.internal, etc.). And some the devices are in the range and some not.  [Mixed comments on what is needed in forum topics.]
• I have added the domain-name(15) in the DHCP options

Most everything else is functional -- traffic flow is good, dhcp assignments work, dhcp options work properly (except domain name).

Converting from ISC DHCP to dnsmasq.  Things are basically working -- IPs assigned, DNS lookups working, traffic flowing.

Some details are a bit odd.  [I will open another topic later.]

When I view the Dnsmasq Leases, I see most static entries (imported) with Expire dates of Dec. 31, 1969.  Seems a semi-reasonable thing, I guess.  Nothing is expiring after over 24 hours.  However, I have one static entry that shows an Expire date of tomorrow and one that shows Nov. 5, 2025.

Are these just display anomalies that won't really affect anything?  [I'll try to update after tomorrow].

Missed this in the documentation:   :-[

https://docs.opnsense.org/manual/gui.html#page-navigation

Although the page numbers and last page button (») are always visible, they can only be used when the size of the dataset is known upfront. In case of large datasets, such as intrusion alerts and log views the number of records is not known upfront, since there's no relation between the size of the underlaying data and the number of records.

Version 24.1.6

I am seeing a minor issue on the log pages that have forward and backward navigation. The "skip to end" function (>>) only goes forward one page at a time.  The skip to start (<<) works as expected.

The log pages I have seen this in are (same code?):
    Firewall - Log files - Plain View
    System - Firmware - Log Files
    System - Gateways - Log Files
    System - Log Files - All

I found I had better performance when I turned off Zenarmor.

I'd be interested as well.
My ISP bandwidth is 300 Mbps up/down. 
With 23.1 WG was about 10% off that.
With 23.7 it is about 40% off that with no changes on my side.
