You're forwarding 192.168.0.128:80 onto localhost:80, but ssh won't let you do that 'cause the port is in use (probably by a web server you have running on your local machine?). Try changing the local port to something like 2280. --Erick At Wed, Mar 28, 2001 at 11:53:17PM -0500, Michael Richards said this: :: Hi; :: :: I've got an odd situation where a development machine behind our NAT :: firewall has to go into test production with a desktop client.
