Hi freebsd-net@ mailing list, Right now, my firewall is a HP T730 thin client (with a Dell Broadcom 5720 PCIe NIC) running FreeBSD 12.1 and IPFW's In-Kernel NAT. My ISP is "Wave G" in the Seattle area, and I have the Gigabit plan. Speedtests usually give me 700 Mbps down/900 Mbps up, and 250-400 Mbps down/800 Mbps up during the Coronavirus crisis. However, I'm having problems with an application (Tor relays) where I am not able to use a lot of bandwidth for Tor, Coronavirus-related telecommuting or not. My Tor server is separate from my firewall. Which firewall gives better performance, IPFW's In-Kernel NAT or PF NAT? I am dealing with 1000s of concurrent connections but browsing-level-bandwidth at once with Tor. Also, I hope you all stay safe and healthy during the Coronavirus crisis. -Neel === https://www.neelc.org/
