The wget command I posted in my previous mail was supposed to be run
from node A (IPv6 client), not B (Jool).
If you want to run it from Jool, you have to use IPv4:
kunal at B:~$ wget http://34.196.x.x
Alternatively, try curl:
kunal at A:~$ curl -g -6 http://[2001:ab5::34.196.x.x]
kunal at B:~$ wget -g http://34.196.x.x

1. Please give me the exact output of these two pings:
ping6 2001:ab5::34.196.x.x # Run this on A
ping 34.196.x.x # Run this on B
2. Is node C outside of your domain? Do you have a terminal on it?
3. Which version of Jool are you using?

Given a packet that comes from node A,
Its source address will become Jool's pool4 address (172.19.61.209)
Its destination address will be translated with pool6 (2001:ab5::/96)
For example:
1. You're trying to send 2001:ab5:0:1::X -> 2001:ab5::34.196.x.x from node A.
2. The source address is translated with pool4, so it simply becomes
172.19.61.209
3. The destination address is translated with IPv6, so we remove
2001:ab5::/96. So 2001:ab5::34.196.x.x becomes 34.196.x.x
4. The outgoing packet is 172.19.61.209 -> 34.196.x.x
