I just had Fidium Fiber installed with my TL-R600VPN plugged directly into their ONT.  The router received one of their IP addresses, and everything looks good from their side, but nothing on my side can do much of anything.  I can't get to web pages or even run Speedtest.  Sometimes tracert works.  If I connect to the comcast router that is still running, everything works fine.

The reason for the question in the subject line is that I am getting strange results when using the diagnostics under system tools of the router to do Tracert and Ping - By the way, I have multiple WAN ports configured on the R600, with Fidium connected to WAN1 and Comcast connected to WAN2: 

- ping of www.google.com via WAN 1 works fine

- ping of www.google.com via WAN 2 works fine

- Tracert to www.google.com via WAN 2 works fine

- Tracert to www.google.com via WAN 1 sends back either 10.10.10.10 or **** for every hop

So, Do Ping & Tracert from the router management interface bypass the firewall in the TL-R600VPN?  If so, then I think it is safe to say that there is something messed up on the Fidium side.  If not, then I suppose there could be something going on in the TL-R600 that is messing up my internet access, although I find it hard to believe that Comcast would work fine at the same time that I can't do pretty much anything with Fidium.

Thanks,

Tom
