We changed ISPs and in doing so we changed our IP addressing. We are behind a firewall on a private network. When we attempt to hit sites on the internet, about every 10th one we can't get to. We have flushed the DNS and actually went to OpenDNS. Most sites are accessible but many aren't.

Doing a tracert to one of the sites, I seem to get stopped at our router.

Any thoughts?

If you are not even making it outside your network then it sounds like your router may be bad. Do a a few more tracerts. If some are making outside your router but have timeouts along the hops then your ISP may have a problem on the circuit.
