This one has my brain burning a bit...

I have set up NAT on an Internet router for a business and some Microsoft
folks that also support them need the GRE protocol passed through the NAT.
I did a one to one NAT statement (ip nat inside source static <inside local>
(inside global) which apparently didnt give them what they needed. Since
GRE is a PROTOCOL rather than a TCP/UDP port range I am at a bit of a loss
as to how to do that. Do I need to change that association to an ip nat
outside source statement instead?
