Read the vlan docs for how to change the interface names to something like
vlan50 instead of eth0.50 This works for me:
vconfig set_name_type VLAN_PLUS_VID_NO_PAD
...or upgrade to iptables 1.2.5 or higher (1.2.6a is out). This is from
the 1.2.5 ChangeLog:
* make iptables accept '_' and '.' in interface names
