Dear all ...
Sorry for this probably stupid question.
I have a router with public IP connected to local network.
I need computers to connect to VPN. This is quite easy. I can ping computers from the local network but I cannot access them by computer names.

Does anybody have any idea?

Thanks

If you mean network discovery It is not posible, because the network discovery is using NetBIOS protocol witch can not be routed.

Another way to use computer names is having a DNS server in you LAN, with the registers of all computers names. Then, when you connected via VPN you can use this DNS server to reach the computers by name.

Regards.

Windows uses WINS to resolve hostnames. On your remote PC's when they connect have the clients configured to use your internal Windows server as both DNS and WINS.

On the remote site you may also need to suffix your hostnames with hostname.yourdomain.com to get them to correctly respond.

Mikrotik can do this automatically in dhcp but not PPTP.
