I need to setup several LAN to LAN VPNs to carry untrusted (public access) IP traffic across a private network. At each site I will use a PIX 501 and L2 switch or a L3 switch. My question is what is the most cost effective method of concentrating the VPNs? There will be no more than 10 VPNs with 10 users at each site so a VPN concentrator seems overkill - can anyone recommend a Cisco product to fulfil this role?
Many thanks for any advice
