Hi, is this a flat L2 network between HO & Branch?

[Sihanu N]

Hi Syed,

Yes this is a flat L2 network.there is no router or firewall in the network..

Thanks,

If this is a tryue flat L2 topology (bad idea) then you must make sure all of your hosts have the correct subnet mask, and that should be 255.255.0.0. check some of the affected hosts for this issue.

Then get some routers.

Regards

Stephen
