In

Is there any way to specify which interface should be bound on gateway

I found
https://unix.stackexchange.com/questions/16057/use-ssh-with-a-specific-network-interface
And my ssh manpage has indeed got a -b to change the bind address on
your initial outgoing connection and also -B to change bind interface.
The rest about binding for the listening onb a fwd is indeed not
helping your cause.
Ah I misunderstood. You want the machine called "gateway" to bind
against a specific interface when doing the forwarding. I had assumed
this to be done by your choice of IP in the portion before the first
port the "webserver" being remote and the part you want to route out to
but I think I can see the issue now. How do make sshd choose to use a
particular binding for a host. I can't see a -b in man sshd but man
sshd_config does have GatewayPorts. Otherwise route update or socat
sound reasonable.
