Firewall appliance hardware is a good choice for new users to OPNsense since it offers an affordable, quiet, and energy efficient solution in a small form factor (similar to consumer grade routers).If it is a virtual pfsense, you could be hitting an issue due to use of paravirtual (or whatever they are called) NICs. You may need to disable hardware checksum offload as described on this page: Virtualization — VirtIO Driver Support | pfSense Documentation You can also use a virtual NIC model like Intel e1000, that might do the trick as well. cfa books schweser The difference I am looking at, at the moment is the good server is using a MSK card that has no hardware features like checksum offloading, no TSO but does have hardware VLAN. The bad server is using a NFE card which currently has RXCSUM,TXCSUM,VLAN_MTU,TSO4 enabled, its also sharing a irq with a usb port.The settings for Hardware TCP Segmentation Offload (TSO) and Hardware Large Receive Offload (LRO) under System > Advanced on the Networking tab default to checked (disabled). 3.

For an explanation on why this needs to be done, there is more information in ...Just received new SG2440 from pfsense store. I noticed that the following two options are checked (disabled): Disable hardware TCP segmentation offload. Disable hardware large receive offload. I would think the intel nics in the new boxes should be able to handle these…any reason I should not uncheck?Hardware LRO (Disable hardware large receive offload) VLAN Hardware Filtering Specs on the firewall are i5-7200U / 6 port Intel 82583V NIC / 16GB RAM / 256 GB SSD. Under System -> Settings -> Miscellaneous I have turned on aesni since I know the CPU supports it. Any other "tuning" advice would be appreciated. 1 comment 100% Upvoted bungalows for sale in eastham and bromborough
