I have a masqerading firewall that is the gateway for my network.
Since installing 2.0.30, the syslog has been filled with the following:
MASQ: failed TCP/UDP checksum from xxx.xxx.xxx.xxx
This really happened during a fetchmail session from my ISP. What sould have
taken only about 20 min or so (300 messages), took over 3 hours due to the
firewall having to recover from these errors.
