23.1 Legacy Series / Unable to add static ARP entry

« on: March 20, 2023, 03:18:47 pm »

I have an ONT that allowed communication over a local IP space but loses connection every X minutes if the device is not ARP'd. To get around this, a static ARP entry is required for its MAC, but I'm unable to add it for that space

Code: [Select]

root@opnsense:~ # arp -a | grep 192.
? (192.168.1.2) at b4:96:91:21:c9:76 on ix1 permanent [ethernet]
root@opnsense:~ # arp -s 192.168.1.1 MAC_ADDR
arp: cannot intuit interface index and type for 192.168.1.1
root@opnsense:~ #

For reference, 192.168.1.2 is an alias IPv4 address attached to the WAN interface in the interface settings. 192.168.1.1 is the address of the ONT in question.

Any hints?

Hardware and Performance / Poor routing performance on DEC3840

« on: May 23, 2022, 01:22:25 am »

Doing some testing cross-VLAN I noticed I'm only able to get about 8-900Mbps or around 3Gbps of fully-threaded routing performance.

My switching hardware is mostly unifi, using DACs between the firewall and the switch.

Any settings/tunables to check for any obvious performance issues?

EDIT: The test is being run between 2 VMs on the same proxmox box in different subnets.

If I try to run iperf3 from the opnsense CLI from one interface address to a VM on a different network, I actually get full 10Gb speed, but whenever traffic is coming into the opnsense router first (from a computer/workstation, VM, etc), then back out routed is where the performance issues happen.

22.1 Legacy Series / DEC3840 Config import no login prompt

« on: May 21, 2022, 05:11:58 pm »

Hello, I just received my new-to-me DEC3840, trying to install 22.1 and restore a 21.7 config, but after a reboot, I don't get a login prompt.

I assume I should try installing an older version? Is there a way to get my config compatible without having to go through an upgrade path?

Thanks.
