Can you do an extended ping from the ethernet interface of your branch
routers to the ISP router? (ie Does the ISP router know how to get back to
your local LAN's.)
The only ping you've mentioned that does work is from your branch router to
the ISP ethernet. As far as the ISP router is concerned this only involves
directly connected subnets. What routes are there on the ISP router?
Your next step after that is to confirm the connectivity from the ISP router
to the Servers and back. Can the servers get back to your branch subnets:
Do the servers use your ISP router as default gateway?
If not, does their default gateway know how to get to your branch subnets?
Depends on your IP addressing scheme as to whether it matters, but not
having 'IP classless' in the config can mess things up.
Something to start with anyway.
