By meanigful traffic I mean traffic like Http traffic

Am able to ssh no problem.

Most of the clients on the link are using it for browsing.
However we find that even though they are able to resolve and ping different sites.
When it comes to opening of the page we have the page reading as opening opening .. but the page never gets opened.

Regards,
Jacob Miller

What exactly do you mean by meaningful traffic? ICMP from port to port works, can you pass TCP? SSH between routers? Establish a TCP session over it?

Are you using Juniper SRXs ? :-)
