Unfortunately, since GRE is an IP protocol, it requires having two IPs on the endpoints that can route directly to one another, or in your case a NAT router that can support forwarding IP protocol 47 to your NATed endpoint. > What is my best option to build a GRE tunnel betweent these two > routers?

JunOS has a DHCP client, just set the "dhcp" option under your iff (interface .... family ....) interface and any associated options that you'd like.
