If needed, you can change the default maximum number of ports available for PPTP, L2TP, SSTP, and IKEv2 VPN tunnels in RRAS.

To configure ports

Fill out the Configure Device dialog box as shown in the following table. For information about how to configure ports for your site-to-site connection, see Enable Routing on Ports.

Option Action

Remote access connections (inbound only)

Select this option if you want to allow connections from individual remote access users in addition to connections from a remote router.

Demand-dial routing connections (inbound and outbound)

Select this option if you want to enable a site-to-site demand-dial connection. This is the default.

Demand-dial routing connections (outbound only)

This option is available only for a PPPoE connection to the Internet. Select this option if you want this router to function only as a calling router.

Phone number for this device

If you configure a value for Called Station ID in the remote access network policy associated with this connection, you must manually type a value for this field:

  • If this is a dial-up connection, type the phone number that was entered in the Called Station ID attribute of the remote access network policy.

  • If this is a VPN connection, type the IP address of the VPN server (entered in the Called Station ID attribute of the remote access network policy).

Maximum ports

For PPTP, L2TP, SSTP, and IKEv2 VPN routers, change the default number of ports. For optimal scalability, use 10 or fewer ports.
