21.7 Legacy Series / Re: Low throughput on LAN

« on: October 19, 2021, 09:51:30 am »

hypervisor is KVM (proxmox), virtual NIC is Virtio. Yes, i am testing without any firewall shaping rules (just outbound NAT). Nothing is running hot during the network activity (monitored by HV and zabbix)

21.7 Legacy Series / Low throughput on LAN

« on: October 19, 2021, 09:13:00 am »

Hello, i use OPNsense like as a virtual server with these parameters: CPU: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz (4 cores),  memory RAM: 4GB+Swap. All our network adapters are join with 10GB/s (f.e.    public Ethernet 10Gbase-T <full-duplex>ip). I tried to iperf to wan interface with relatively (in comparison with lan speedtest) good results (always more than 3GBs). My LAN computer is connected with 1Gb/s. But when i try to speedtest (with the closest servers), i cant measure more than 300-320Mb/s down/up. In our network, i also tried simple virtual router (with ipconfig) and speed are always near 1Gb/s and the same result when i try it with device Unifi dream machine Pro. Where can be a problem? I installed opnsense because it looks to be a great device for our network.

hello, yesterday, i fixed this issue, but i am not sure how...i suppose, that only another thing i did is, that in interface settings on my LAN networks i press to +  IPv4 Upstream Gateway and than save the settings

21.7 Legacy Series / Routing LAN->WAN doesn't work

« on: October 14, 2021, 02:44:41 pm »

Hello, first of all, sorry for my English, i am in troubles. I installed opnsense software, because it looks to be great tool for our network, but i cant set NAT as i want.

In my opnsense network, i have have 3 separated networks 10.1.x.y/16, 10.2.x.y/16, 10.3.x.y/16 and WAN network ABCD. I set roles for all networks, run a Outbound NAT in Hybrid mode. When i add computer to one of LAN networks, i cant access the internet and also i cant ping 10.1.0.5 (OPN LAN) ip adress (Destination Host Unreachable). When i try to nmap, it shows me host is up with good MAC adress (so i know, that this network card is working). When i allow everything in firewall (for LAN network both directions) i also cant ping OPN LAN adress, which i weird. I also tried to add some other LAN and WAN rules, but nothing works.

I saw lot of manuals and topics with the same or similar problem, but i can't find the solution. Can you help me and write som instructions, what i need to do? Thank you for your time and advices.
