Did you test from clients with different public IP addresses (not 
masqueraded behind the same NAT device) ?
AFAIK the generic connection tracking and NAT should handle properly 
multiple GRE tunnels between a masqueraded server and multiple clients, 
provided that the server sees a unique IP address for each client so 
each tunnel creates a unique conntrack/NAT tuple.
