Hardware and Performance / Re: Bandwidth slow through firewall
« on: August 19, 2020, 01:34:59 am »
Sorry to resurrect this older thread but I'm on my 2nd week trying to get my customers OPNSENSE firewall to increase throughput. At the present time i have OPNSENSE running as a VM under Proxmox. All network resources are being recognized as 10GBE. We have increased our ISP account up to 1 Gbps.
Just like the previous poster if i plug my laptop into the modem i get speeds approaching 1 Gbps. When i run through OPNSENSE and plug directly into the LAN port it appears that OPNSENSE throttles the speeds to no more than 360 Gbps.
I've edited the LAN MSS with 1400 as recommended....but no changes.
Nothing special with OPNSENSE - Just a fresh install with the WAN and LAN ports. No NAT, proxies, etc.
In testing I've tired a few other firewall packages (I hate them) but wanted to see if i was dealing with a hardware issue. I've installed PFSENSE and have the same issues....throughput is throttled to about 360 Gbps.
However, i've installed IPFIRE - using the exact same hardware configuration and SURPRISE! I'm able to achieve almost 1 Gbps throughput.
I'm confident this is some type of configuration setting......I love OPNSENSE but need to get this figured out.
Any help would be appreciated!!
