Ping is an ICMP [1] echo request/reply protocol and it uses UDP [2], so transmission of packet is not guaranteed. But, SSH uses TCP [3] protocol, which is a stateful protocol. A session is maintained between machine A and B. When the OP is able to SSH between his machine and the remote, as per TCP sequencing, the remote machine will send back information. So, the question of routing between the remote machine and the local machine shouldn't come because SSH already works from OP's machine to the remote machine. Please capture packets using Wireshark to see the network traffic between the two systems.
