Hello everyone
I'm using OPNSense since winter and it's the most stable and reliable product I've ever seen, 200 days uptime, great job. Had some issues with new Intel nics pci-x, went for older ones.

So I have two requirements and I don't know how to solve them:

1. Failover multi wan setup with proxy

The network computers have internet access through http proxy (not transparent) only.
The network file server has full internet access and port forwarding.
When the main gateway fails OPNSense switches the backup one, but the computers no longer have internet access, only the server has.
How can this be fixed?

2. I'm achieving dns failover using a small c# service which updates the IP for the subdomain automatically in cpanel.
The subdomain points to both OPNSense wan IP, backup and main, I've added port forwarding rules for both gateways.
The dns resolution is provided by a hosting company, short TTL.
The simple c# service running on the file server does a "my IP" check each minute and if that has changed it updates it with a https request to the hosting cpanel API.

How can this process be performed on OPNSense, is it possible to trigger a script when the main gateway failed, or can I write a plug-in for that?
Where to start with this?

Thank you

Hello everyone

I have upgraded to 17.4 yesterday and have some strange bahavior now.
Upgrade itself was working normal without any errors, exept ids was not strted and I had to reboot.

I use simple nat with 1 wan dsl connection.

After the update it seems like after 15 minutes all _new_ connections going to wan are blocked.

I can ping for e.g. 8.8.8.8 on my pc without any problems, even after 15 minutes when I ping permanently.
But when I try to do simple web surfing after these 15 minutes no connection is possible. Even from the opnsense itself I am not able to ping 8.8.8.8 for e.g.
In the dashboard I can see, that the dsl connection is still up and running. Even the ping from my pc I started directly after rebooting is still working. But any new connections do not work.

When I try to reconnect the wan dsl connectionit will not come up again.

To solve the problems I have to restart the opnsense.

After restart it takes a long time before the dsl connection is up again (20 to 30 tries in log file), but then everything is working again for around 15 minutes.

My hardware is an APU 1 board (realtek cards).

Anyone got an idea what is going wrong?

For me it looks like the firewall is blocking connections after these ~15 minutes, I can´t find any problems in other logs (pppoe, system hardware etc.)

Thank you

Hi There เล่นคาสิโนบนมือถือ

I would like to know if it would be possible for me to limit the amount of bandwidth that can go through a specific port on the NIC inside the server.

For example:
I have a opnsense server with 1 onboard NIC, and an external 4 port NIC. I use the onboard NIC for the WAN, and the incoming connection is 100mbps. I would like to share this connection as 25mbps per port.

Would that be possible?

Thank you

Hello everyone

I'm using OPNsense from few mounts now and I love it! But I want to make my home network just a little bit more organized and I need your help because I'm lost...

Recently I've manage to get HP ProCurve 2626 (J4900C) for $10 from eBay and after resurrecting one old HP 6005 Pro (AMD ATHLON II X4 645, 16GB Ram, 2x2TB HDDs) I'm ready to start!

That is old hardware - I know that, also there will be issues like old firmware, etc. - I know that also - but for the moment I can't invest any money to make it better, so I need to work with what I have.

So after few days of cleaning dust, changing thermal paste and preparing small place where to put everything I want to make something which will work and will be practical, so here is my idea:

Proxmox as main OS
OPNsense as guest VM
Another VM for few lightweight WEB apps เล่นคาสิโนบนมือถือ

So far, so good but here is my problem: My machine have only one NIC and I want to use it for so called "router on a stick"

What is my topology:

ISP up-link enters my apartment - it's a cat6 cable without modem/router and this cable is connected to one of the Gbe ports of my switch
the host machine is connected to the second Gbe port of the switch
few ports are occupied by dummy APs, 2 PC and 3 SBC's

What is my issue:
I don't know how to set all VLANs and briges correctly so the OPNsense VM to act as normal router so, all hardwired/wireless devices to get their IP from OPNsense's DHCP, and all other VMs to be able to access internet also.


So I ask for advice and ideas of everyone.

Thanks to everyone who offered the idea.
