Only allow local connection for ssh forwarding

Post by jones5000 »

I wish if it was posible to only permit local connection to secure the server to only permit local connection via a ssh tunel .
I think this is not posible now in ultraVNC , but is posible in TightVNC :(

Thanks

Did you check both Registry settings in
HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3


LoopbackOnly: Setting this entry to 1 causes WinVNC to accept loopback connections
AllowLoopback: Setting this registry entry to 1 will cause local-loopback connections to be allowed. Setting it to zero will filter out such connections
