http(s) over ssh tunnelling

if machine A stands in DMZ(before the firewall) and B is part of the corporate network (behind the firewall),
on the machine A :
# ssh -gNL 33333:B:443 root@B
for example:
# ssh -gNL 33333:192.168.1.119:443 root@192.168.1.119
-g - Allows remote hosts to connect to local forwarded ports.
this will cause https://A:33333/ to work just like https://B:33333/ but from outside the network.
