Dlink router blocking Symantec server

i started noticing this in my dlink router log, INFO] Tue Nov 09 10:45:46 2010 Blocked outgoing TCP packet from 166.98.6.30:80 to ###.#.##.##:49533 with unexpected acknowledgement 2863444291 (expected 1443073081 to 1443138601

 

The ip address in question is a symantec server but not sure why it's being blocked. Never had any problems before but it seems it's just started. monday, Live updates work fine, only think I 've noticed is Norton safeweb servers are a little slow.

 

I keep seeing these unexpected acknowledgement over and over again for the ip address 166.98.6.30:80

 

did a look here, http://whois.arin.net/rest/net/NET-166-98-0-0-1

 

I am thinking it has something to do with norton safeweb because some times when i do a google search it doesn't show the little green boxes. it something up with the norton safeweb servers?
