I'm forwarding TCP connections coming to me on a particular port to the other interface. It works fine when the connection originates from the outside host. It doesn't work when the connection originates from my own host. The description is here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239590 Connections originating from my own host are automatically made on lo0, and the same ipfw rule that works on the physical network interface doesn't work on lo0. Is this a bug, or am I doing something wrong? Thank you, Yuri
