There is a site to site IPsec vpn. Site A is 18down/3up Cable broadband, Site B is 18down/18up dedicated line. Not taking in consideration overhead or inconsistency of the broadband ISP.
It is my understanding that the VPN tunnel bandwidth would be 3up/3down. However, my colleagues which are much more experienced than I am, informed me that it would be 18down and 3 up. Can someone please clarify this for me and provide me a location where I can read about this.
