Microhard Systems VIP4G - IP-Passthrough

© Microhard Systems Inc. 68
4.0 Configuration
IP pass-through allows the 4G WAN IP address to be assigned to the device
connected to the physical LAN or WAN Port (DHCP or Static). In this mode the
VIP4G is for the most part transparent and forwards all traffic to the device
connected to the specified port except that listed below:
 The WebUI port (Default Port:TCP 80), this port is retained for remote
management of the VIP4G. This port can be changed to a different port
under the System > Settings Menu.
 The SNMP Listening Port (Default Port: UDP 161).
Local WebUI of the VIP4G is retained by using the first 3 octets of the Wan IP
and changing the last octet to 1.

In some cases, a user may want to lock onto certain carrier to avoid data
roaming. There were four options presented to a user to choose from, Auto,
SIM based, Scan & Select and Fixed.
 Auto will allow the VIP4G to pick the carrier automatically. Data roaming is
permitted.
 SIM based will only allow the VIP4G to connect to the network indicated by
the SIM card used in the unit.
 Manual will scan for available carriers and allow a user to select from the
available carriers. It takes 2 to 3 minutes to complete a scan.
 Fixed allows a user to enter the carrier code (numerical) directly and then the
VIP4G will only connect to that carrier.
