Mapping Folder within VPN

By Working IT ·
I have a VPN setup with a Cisco router. My internal network is setup with IP 111.111.111.0-254 and Mask 255.255.255.0. And for the VPN connection, IP are set to 222.222.222.0-254 with a Mask of 255.255.255.0. Within the VPN, I can ping to the Internal network without any problems. But I can't use the "net use" command to map any network drive. Please help!

You didn't give the exact NET USE command you are using but I have seen similar problems with remote drive mappings. We have had better luck using the fully qualified server name - \\server1.company.com\share instead of just \\server1\share. The server name will resolve quicker with a DNS name rather than a netbios name which prevents the time out problem I think you are having. We changed that in the login scripts as well. Good luck.

The exact command I used was "NET USE T: \\SERVER_IP_ADDRESS\SHARED_NAME". Base on your answer, my problem is not caused by the difference of the IP settings between the VPN and the Internal network.

see if you can ping the ports used by netbios? you need netbios to map drives, isn't it?
maybe blocked at the router...it is considered an insecure protocol because of plain text passwords, i think...just 2 cents

good question. you don't use ping. you use telnet. the command is telnet <server address> -<port number> if you get unreachable or similar you know you got firewall blockijng that port.
and since i already passed my a+ cert i will leave it to you to google 'ip ports' and find yourself a handy list to look up this stuff...

What is the default port# for netbios? And how do I ping a specific port#?
