Title: DIR-825 Blocked incoming TCP packet from ... to ... with unexpected sequence
Post by: FUBARinSFO on July 17, 2009, 07:17:06 PM
Hi:

With SPI enabled, I'm getting lots of blocked packets.  Below is a section of the log, showing one remote system trying to access my bittorrent program port.  The '48836' port is the NAT port of utorrent, hosting 200 torrents.  I'd like to better understand why I have to disable SPI in order to suppress these warnings and allow the presumably legitimate packets to go through.

Thank you in advance for your help.
