Problem Description: IP packets that should be forwarded after being decrypted
out of a IPSec tunnel are not forwarded.

B is the gateway between A and C.
A<------->B<------->C
First check that ping from A to C are working. If not check forwarding options
in B.
Then create an Ipsec tunnel between two hosts A and B.
A<========>B<------->C
