Tweaking MTU

[MrChips]

Hi,
I've just used the optimiser for the first time. I tried the MTU tweak to find the optimum MTU. When I pinged I got an error message "Host does not accept ICMP pings" I tries all the other URLs and all gave the same error?
Any suggestions?

pings may be blocked on your end by your router/firewall ?

I'd try "tracert" or "ping ...." in command prompt.

Thanks for your suggestion
I tried a " tracert 4 " ping and got an error message
I tried the MTUtweak in the TCP optimiser again with firewalls off and gtr the same error message as before.
I'm puzzled
