Question regarding the IPsec VPN implement

jlee9168 · ‎07-01-2010

Hi Experts,

We will setup IPsec VPN over GRE Tunnel in the HQ& branch office environment( Hub & Spoke) use the cisco ISR 3900 serial router. But currently the HQ(Hub site ) site have the Juniper firewall ( HA configuration) directly connect to internet. Just want to know how to implement the cisco 3945 router before the Juniper firewall to setup the IPsec vpn over GRE tunnel between spoke site.

Your kindly information is very appreciate.

Best Regards,
