So the default is now UDP instead of TCP.
In the lab we will have 12.4 so this won't be an issue. I think :)

Subject: 3640 SNAT cannot use TCP to talk to peers, not compatible with
older 12.3 routers
Appreciate any response,
my 3640 is c3640-ik9o3s-mz.124-8a.bin
the 12.3 router is 2600, which doesn't have choices with
the transport layer.
my 3640 refuses to use TCP:
