I'm sure that this must be a FAQ item, but I looked and did not find it.
Anyhow, let's say that I have the following setup:
+-----------------------------------+
| |
| |
| |
| |
REMOTEFIREWALLHOST MYHOST
|
|
|
REMOTEINTERNALHOST
REMOTEFIREWALLHOST has a REAL IP address
REMOTEINTERNALHOST has a fake IP address ( 192.168.2.x )
MYHOST has a real IP (or fake, but NATed/masqueraded) address
Port 22 (SSH) on REMOTEFIREWALLHOST is forwarded to REMOTEINTERNALHOST
port 22 via 'redir'
I can already SSH from MYHOST to REMOTEFIREWALLHOST and it pushes me
through to REMOTEINTERNALHOST (which runs sshd2).
I want to be able to SSH from MYHOST and have local (MYHOST) ports
forwarded a port on REMOTEINTERNALHOST. Eg, port 8080 on MYHOST would
forward to port 80 on REMOTEINTERNALHOST. I can't seem to get this
going.
I've tried: ssh -L 8080:REMOTEFIREWALLHOST:80 REMOTEFIREWALLHOST
but this does not work. I'm assuming that this is because
REMOTEINTERNALHOST is not a real IP.
Suppose REMOTEINTERNALHOST's IP (fake) is: 192.168.2.222
I've also tried:
ssh -L 8080:192.168.2.222:80 REMOTEFIREWALLHOST
ssh -L 8080:127.0.0.1:80 REMOTEFIREWALLHOST
ssh -L 8080:localhost:80 REMOTEFIREWALLHOST
The latter two appear to resolve to MYHOST, instead of the localhost
where the sshd2 is running...
Is there an [easy] means to do this?
Does/shouldn't SSH defer the creation of the remote/destination port
until after the connection is established?
I'm guessing that MYHOST tries to resolve the hostname right up front,
rather than letting the sshd2 host resolve the IP/name.
Is my assumption correct or false?
Any help and feedback are greatly appreciated.
Thanks.
