Dear all,

i setup a remote vpn connection.

I want the sale office of my company able to access to our erp system.

Actually when they connect to the vpn they can connect, but they have no internet anymore.

That's mean no email, no web surfing, they just can access to our local server.

Could you tell me how to fix that ?

Thanks a lot !

Fly

Ok.

Then you should NOT have a DNS entry on the External NIC, ONLY your Internal NIC should have a DNS entry and it should be pointing to your Internal DNS Server that should be able to forward external requests to your ISP DNS Servers
