Technicolor Security Log

Hi
Can anyone tell me what the information on the attached screen dump of my router's log is telling me? Is it something to be concerned by? My router's firewall is set to 'high'. I've removed my own IP address.
Thanks

These "Destination Unreachable" messages are nothing to worry about, we all get them.
They're just trivial messages from sites you've visited directly or indirectly (through embedded advertising links etc), the timeout for these messages is quite long so their time stamp may not mean much to you.
Best ignored IMO

Thanks - really appreciate the response!
