I have not been able to find any concrete information regarding running VPN on a PIX firewall or 2620 router as to which one would perform better for VPN. We have a PIX 520 firewall and a Cisco 2620 router (neither one has the hardware acceleration card). Which one would be better for running site to site VPN? We will most likely only have around 10-20 site to site tunnels. Also, we are wondering if it would be better to terminate the VPN tunnel inside the PIX so that the unencrypted packets could then get inspected by the PIX? Or is it better to pass the encrypted traffic through the PIX and terminate the tunnel on the other side (the inside) on the 2620 router? Thanks for your help,
