Is it possible to encrypt all TCP or IP packets going out to a corporate public virtual network without using IPsec. All routers going on the corporate VPN would hardcode this way of doing things (no policy negotiation).
Our problem is that we are using a cisco 3250/30 router and that the GETVPN feature is not available on those router. The GETVPN feature is used in secure networks using multicast. Because we are using multicast, the only other alternative is DMVPN which is less than adequate because each packet is replicated for every destination.
Thank you in advance for your support.
