Have you tried the reset button located between the serial port and the power on light? You could use a paper clip or a sim card removal tool to press it while powered on.

Hi,

I recently moved into a new place and now have an active fiber connection (FTTH AON), no passive GPON, with a small local ISP.
Before I had a DSL connection with a modem in Bridge mode and Opnsense handling PPPoE and Vlan tagging.
Along with the Fiber connection my ISP provided me with a media converter and an SFP Module.

Media Converter: TP-Link MC220L
SFP Module: [FIBER – LR BiDi] SFP-GE-BX 1000BASE SFP 1310/1550 20Km (FS)
Opnsense: 22.7.2

My current setup looks like this:
Fiber -> SFP on Media converter -> RJ45 on Media converter -> WAN Opnsense (igb1)

This setup works pretty much out of the box, no PPPoE or Vlan tagging required, and I receive my IPs via DHCP.

Since the DEC740 has SFP slots I would like to move the SFP module directly to the DEC740 to reduce the number of devices, cables and save a little electricity.

My desired setup looks like this:
Fiber -> SFP on WAN Opnsense (ax1)

When i plug in the SFP module it gets recognized by Opnsense and when I plug in the fiber cable the link is shown as up however I don't receive any IPs. My ISPs tech support also confirmed that the link is up and looking good.

I asked them if I needed to provide them with a mac address or spoof a mac address, they said no.
I asked them if I needed to set a vlan tag, they said no.
I asked them if I needed to pass any special Parameters in the DHCP request, they said no.
They suggested I try PPPoE and provided me with the credentials however I just receive PPPoE timeouts.
I also disconnected the link and waited 4+ hours for the end of the DHCP lease, without success.
I also tried setting the IPs manually without luck.

While researching my problem I came across this issue here:
https://www.reddit.com/r/PFSENSE/comments/pd2kbf/no_ip_on_wan_with_new_isp/
Using packet capture in Opnsense I couldn't rule out having this problem because I only see DHCP Discover Packets sent by Opnsense and no Offer.

In the general log I did notice this error:

Code Select Expand

/usr/local/opnsense/scripts/shell/setports.php: The command '/sbin/dhclient -c '/var/etc/dhclient_wan.conf' -p '/var/run/dhclient.ax1.pid' 'ax1'' returned exit code '15', the output was 'ax1: no link ... got link DHCPDISCOVER on ax1 to 255.255.255.255 port 67 interval 1 DHCPDISCOVER on ax1 to 255.255.255.255 port 67 interval 2 DHCPDISCOVER on ax1 to 255.255.255.255 port 67 interval 5 DHCPDISCOVER on ax1 to 255.255.255.255 port 67 interval 14'

Do you have any thoughts on what I'm missing or how I could proceed?
