[SOLVED] Incorrect checksum on localhost packets, no localhost traffic

I launch a tigervnc's vncserver. Than I launch vncviewer. Vncviewer doesn't connect. Iptables has the ports open correctly, same iptables.rules was working on an earlier installation. Tcpdump on -i lo shows that all the TCP packets to localhost from vncviewer have incorrect checksums.

I don't know about checksums but the connectivity issue for tigervnc was a typo in iptables.rules that I did today.
