46 I found traceroute on the router.  Thing is, it doesn't like IPv6
47 addresses.  It keeps saying "illegal characters".  I can't find it on
48 the modem but I could have sworn it was on there.  I've even looked in
49 menus that wouldn't make sense for it to be there.  Still can't find it. 
50
51 I tried traceroute6 with both options but get the exact same result.  I
52 went to the info the router has for IPv6.  I used ping -6 and am pretty
53 sure I can ping the router.  It receives the ping from what I see.  Then
54 I went to the modem and tried the IPv6 addresses it showed there.  After
55 trying all it shows, ping isn't reaching the modem.  It seems the router
56 is getting it but not able to send it on up to the modem. 
57
58 That sort of makes sense since it shows a IPv6 connection to my puter
59 but the info for the modem connection does not.  I'll send you a reply
60 off list.  Maybe it will make sense with it being unedited.  Subject
61 line will stay the same tho.
