Ipsec Ip Checksum Offload Error.
-
Hi guys,
I have configured multi site , site-to-site ipsec vpn between our head office with Bracnhes offices. When I get some packet capture on the wan interface off the pfsense ı have noticed that there are many Header checksum error on the traffic.
Due the this errors, the traffic between tunnels is so slow it effect all traffic especially RDP or file sharing traffic. I have capture some errors on the Terminal Servers ,
Header Checksum : 0xcf5 [incorrect, shoul be 0xc3f5 (maybe, casued by "Ip checksum offload "?]
I also disable checksum offload and reboot the gateway on the head office.
How can I resolve this issue on the pfsense.
Best Regards,

Not nearly enough information there.
Is this 1.2.3 or 2.0? Is this i386 or amd64? What kind of hardware is it? (ifconfig -a would help)
