You can add these > parameters to your rc.conf. 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).
