I'm attempting to configure a GRE tunnel over IPSec to a remote network for the first time; my core 6500 switch lacks the hardware for this, so I'm trying to implement two 1700 routers as the headends in both networks.
Are 1700s up to the task of this implementation, or are other routers required?
Can a VPN endpoint device also be a GRE headend device?
We normally find that (depending on exact type of traffic) we can count on a 1721 -WITH- the hardware encryption adapter will push about 1.9mbit (just short of an E1) of mixed traffic (average packet size 1280 bytes) full duplex over GRE/IPSec 3DES.
Your milage may very, but I wouldn't expect much more than that.
