To bypass AllowTcpForwarding no try using socat and nc:

socat TCP-LISTEN:<local port>,reuseaddr,fork "EXEC:ssh <server> nc localhost <remote port>"

For example from your desktop run:

socat TCP-LISTEN:8080,reuseaddr,fork "EXEC:ssh 1.2.3.4 nc 10.0.0.1 3000"

This will listen on local port 8080 connect via ssh to 1.2.3.4 and use nc to connect 10.0.1.1:3000
