Could you be a bit more clear in what you are trying to do?

are you trying to do




Because if you are trying to use your MPLS to connect to your Internet VOIP Provider then that will not work unless you are getting fed an Internet route via the MPLS Cloud. You need to provide a bit more detail to get a correct answer.

Thanks for the quick reply. i am trying to do:

2811-->mpls->internet->voip provider.

I do have an internet feed via the MPLS,which happens to be fed by my same voip provider for another 2811/voip connection (this is totally seperate from my MPLS)the 2nd 2811 is phycally in the UK and it works fine, sending calls over the 10mb ethernet link bet my location and my voip provider in UK. I now have a 2811 here in NY,and i try to send traffic from the 2811 here using my MPLS.

I hope this gives you a more clear picture.

Note: I use the same FW and switch for my MPLS as well as for the 10mb ethernet for internet access.

So you have a seperate connection for internet, it is not provided via the MPLS link? If that is the case you will need to use the public ip ont e 2811




Is this what is should look like if i understand what you have
