Port Forwarding

The ioLogik 2500-GPRS/HSPA supports port forwarding on its cellular and Ethernet interfaces for WAN-to-

LAN communication. Using port forwarding, the ioLogik 2500-GPRS/HSPA allows external WAN hosts such

as SCADA/HMI systems to connect to specific field devices within the LAN by linking with the ioLogik 2500-

GPRS/HSPA.

Ethernet packages from public ports will be forwarded to the assigned Internal IP and Internal Port. In the

example shown above, Ethernet packets from the ioLogik 2500’s port 80 will be forwarded to

192.168.127.50:8000 (IP: 192.168.127.50; Port: 8000).
