I assume the 6 in dhcp6 in your regexp is a typo you introduced while posting. Other than that, did you notice how many fields are between IPv6 and > in your second line? How many fields do you have in your regexp? Otherwise I would also recommend using ".*?" instead of ".*". Unless you really know what you do, that is usually what you intend. (.*? means match a sequence of any charachters, but as few as possible...) gc
