In /etc/rc.conf I changed the line
ifconfig_re0="inet 192.168.1.13 netmask 255.255.255.0"
to
ifconfig_re0="-rxcsum -txcsum inet 192.168.1.13 netmask 255.255.255.0"
Now the problem no longer appears, even with "net.inet.udp.checksum=1". Thanks
for answering this so promptly, hopefuly the re(4) driver can be fixed to
avoid this kind of problem (or the -rxcsum -txcsum added automatically for
this card).
