            Bug ID: 2592
           Summary: -R bind_address not working, always bind 0.0.0.0
           Product: Portable OpenSSH
           Version: 7.2p1
          Hardware: amd64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: sshd

Hello!

At server running sshd with 'GatewayPorts yes'.
There is many active network interfaces:

eth0      Link encap:Ethernet
lo        Link encap:Local Loopback
tun0      Link encap:UNSPEC
tun1      Link encap:UNSPEC
tun2      Link encap:UNSPEC

IP address at eth0 is 10.10.10.10.

After connection:

./ssh 10.10.10.10 -p444 -R10.10.10.10:8081:127.0.0.1:80

I see at netstat:

#netstat -nlpt | grep 8081
tcp        0      0 0.0.0.0:8081                0.0.0.0:*              
    LISTEN      8729/sshd
tcp        0      0 :::8081                     :::*                   
    LISTEN      8729/sshd

#ps axuf | grep sshd
root      8728  0.1  0.5  28004  2680 pts/0    S+   16:37   0:00       
  \_ ./ssh 10.10.10.10 -p444 -R10.10.10.10:8081:127.0.0.1:80
root      7899  0.0  0.1  27932   972 ?        Ss   14:57   0:00
/root/openssh-portable/sshd -f sshd_config
root      8729  0.0  0.5  30492  2724 ?        Ss   16:37   0:00  \_
sshd: root at pts/1
root      8749  0.0  0.1 103316   804 pts/1    S+   16:37   0:00       
  \_ grep ssh

How can I bind port at specified address while requesting remote port
forwarding?
