I have D-Link DSL-2640B router.
I'm not able to connect through Intranet, i.e. to another IP address within LAN, from a PC within the same LAN.
For example, I have activated SwiFTP server on my Android phone. To connect to it, I need to use 192.168.1.50 and port 2121 with an FTP-client. I'm unable to do so.
Same happens with VNC-server, which is 192.168.1.50:5801. Or, I believe, with any other port.
I'm also unable to do printer or folder sharing.
While in the other network, with different router everything works fine.
I'm able to ping that IP. I'm able to login into the router using the web interface and change settings.
As far as I know, "Firewall settings", "Port Forwarding", "Port Triggering" options in the router are for setting up access from WAN to LAN, though I've tried to play with those options too.
Any ideas how to resolve this issue?
