Only thing I couldn't understand was why telnet from A to D works.
It seems like there are duplicates in your routing table.
On B - 10.0.0.0-10.255.255.255 routes to eth2, but 10.0.1.2 routes via
the encryption (if I understand correctly - I have never worked with CIPE).
On both - the 192.168 networks are marked as netmask 240, which means
that they are the same network. You probably want to have them defined
as different networks.
On C - 192.168.2.0-192.168.2.255 - eth0
192.168.0.0 - 192.168.15.255 - 10.0.1.1 (notice that one network is
contained in the second)
You probably want the routing table to read:
B:
192.168.1.0 255.255.255.0 eth0
192.168.1.1 255.255.255.255 eth0
10.0.1.1 255.255.255.255 cibcb0
10.0.1.0 255.255.255.0 cibcb0
192.168.2.0 255.255.255.0 gw 10.0.1.2
default - whatever you use to go on the internet
C:
192.168.2.0 255.255.255.0 eth0
192.168.2.1 255.255.255.255 eth0
10.0.1.2 255.255.255.255 cipcb0
10.0.1.0 255.255.255.0 cipcb0
192.168.1.0 255.255.255.0 gw 10.0.1.1
default - etc.
