4000/5000 Modems’ User Guide
Examples of commonly used ports:
HTTP - TCP port 80
FTP - TCP port 21
TFTP UDP – port 69
VPN Support
The modem acts as pass-through for the standard VPN types (Virtual Private Network)
allowing your client VPN to connect through the modem to your VPN server:
PPTP
L2TP
IPSEC
GRE Tunnel – in this case, the modem needs to be configured with this feature
enabled using AT+BGREIP (refer to the BlueTree AT Command Reference
document)
DHCP Settings
4000/5000 series modems have a Dynamic Host Configuration Protocol (DHCP) server
enabled by default. DHCP enables TCP/IP client automatic configuration. The DHCP
server stores IP information and disperses it to client systems on the network.
In BlueVue Device Manager, click on File then Configuration to display the Modem
Configuration page. Click on the LAN IP Configuration tab to see the default LAN IP
configuration of the modem. In the Ethernet section, the DHCP settings are displayed.
