Hello everyone!
First of all, massive thank you for letting me into this community! I’m excited to be here, to learn, and to help others where I can!
So, I’ve been having an issue that I need help troubleshooting. I’m honestly not sure where to start!
My issue is that my LAN is getting Gigabit Speeds (tested with iperf3) but my WAN slows down to ~300Mbps. I have Gigabit internet through Cox. I am able to get a IP for my WAN, and internet access does work! I just can’t seem to figure out why I’m getting such a significant difference between my LAN and WAN interfaces. My CPU/RAM usage never seems high.
Setup is as follows:(please let me know if I need to include more)
Dell Inspiron 660 mobo
Intel I5-2500K CPU
XCP-NG Hypervisor
4 - Gigabit network cards(Intel onboard, and then 3 additional TP-Link TG-3468)
16GB 1600Mhz RAM - 6Gb dedicated to pfSense
Could this issue be directly due to pfSense being visualized? I DO have XCP-NG guest tools installed on pfsense.
I have changed which NIC I use for LAN/WAN - seems to make no difference.
I have configured my settings as per suggestions made online, disable offloading and so on, makes no difference.
What am I missing? Is the firewall making my speeds this slow? when I use my Cox router, I can get gigabit speeds no problem, so not a cable issue.
Please assist - I’m honestly not sure what to do. I’ve rebuilt the pfSense box now several times over to try and fix the speed issues.
Thank you everyone in advance!!
