I have an opnsense firewall to isolate a network.
To connect on the isolate network, I connect to openvpn 'opnsense'.

PC <> switch1 <> opnsense <> switch2 <> server

Opnsense have 2 interfaces,
interface1: to connect on switch1
interface2: to connect on switch2

I did the speed test with iperf, on 'PC' to 'opnsense' (interface1), and 'server' to 'opnsense' (interface2), and the gigabit network works.

For the PC connect on interface2, I need to use openvpn.
But, the iperf test between 'PC' (with openvpn) and 'opnsense' (interface2), or 'PC' to 'server', connection speed work with 100mbps.

My entire network is gigabit.

[vtnet0: WANName: WANvtnet1: LANName: LOSEvtnet2: OPT1Name: SERVICE]

I've been using opnsense for years.
Today, I removed a "LOSE" network interface that I am not using.

My old setup was like this.

vtnet0: WAN
Name: WAN

vtnet1: LAN
Name: LOSE

vtnet2: OPT1
Name: SERVICE

Now it's like this.

vtnet0: WAN
Name: WAN

vtnet1: LAN
Name: SERVICE

I restarted opnsense, and asked to assign the interfaces.
All my settings on the "SERVICE" interface have been lost.
Now I'm trying to restore the settings as I know it's saved in the /conf/config.xml file.
But I do not know how to do this, can anyone help me?

I have two networks, in VPN "IPSEC"

172.16.0.0/24
172.16.0.1 - opnsense
172.16.0.50 - zabbix-ct
172.16.0.108 - repository-ct

172.16.10.0/24
172.16.10.1 - opnsense2
172.16.10.10 - gameserver-ct
172.16.10.51 - storage-ct

Zabbix-ct ping in repository-ct
Gameserver-ct ping storage-ct

But zabbix-ct does not ping gameserver-ct
Ping works if you put the IP, but the name does not.

My internet is 50mbps download and 30mbps upload.
But when opnsense is the gateway, it gets 3mbps of download and upload.

what's up?
I saw that other people have this same problem, both in pfsense and opnsense, but I did not see any solution.

Can anybody help me?
