|
I've been reading for several hours now. I think my problem is isolated to dd-wrt. Within my LAN I can ssh from Windows putty directly to my linux server, and I can also run VNCviewer over that SSH connection. However, when I SSH to the router WAN IP the putty SSH text connection works (I'm port forwarding the port I'm using for SSH access to the LAN-side linux server), but the VNC over SSH traffic is refused with VNCviewer saying "The connection closed unexpectedly." TightVNC says something about a graceful exit.
I see a lot of discussion about setting up the SSH connection to dd-wrt, and then hopping to machines on the LAN, which seems like more work than should be necessary. On the Centos 7 server I've tried SE permissive and firewall off, with no joy.
If my simple port forward of the SSH traffic wont work for VNC traffic, can someone explain why, please? I would assume that through the SSH tunnel from my external box through the dd-wrt port forward to the LAN-side server that dd-wrt couldn't know that there is VNC traffic in the tunnel. Bad assumption?
thx,
