I am currently running a company's FreeBSD web server and I am constantly
receiving the ICMP Bad Checksum warning.  It tells me that the severity is
low, but I've read that it may be best to block such traffic.  This advice
comes from

My question is should I try to block this traffic, and if so, what is the
best way?  This is my first time managing a UNIX-based server and am really
loving it, but still have a lot to learn.

Thanks in advance.
