Re: to tepatel

have a seperate router/firewall for access to the internet.

shanghi--------->beijing (headend router) -----fasthethernet---firewall---internet.

If you have a local Cisco office they can help with the DSU/CSU selection that

could be built into the router. this works will with frame relay.
