Firewall Tab

[breese]

When I click on the Firewall tab I see Time, Reason, Source IP, Port, Dest IP, Port, Protocol, Info
Some of the entries are see do not make sense to me and there is never anything listed in Info
Time: I understand
Reason: Port Range (I understand), Checksum Failure (why?)
Source and Dest IP (I understand)
Port N/A (Why?)
Protocol (I understand)
Info (Like I said, I have never seen anything listed here)

Hi

Checksum Failure: the packet was discarded because it failed checksum validation. All IP packets have checksums in the header, and TCP headers have checksums as well so you can tell if a packet was corrupted in transit on the wire.

Port N/A. Only TCP and UDP have a field in their header relating to port. ICMP for instance doesn't have ports.

Info. Only time you're likely to see anything here is if the packet was a DNS request, in which case it gives you info about what is being looked up.
