Overview

Serv-U Gateway by default does not listen for Serv-U control connections on 1180 on any public IP addresses as most customers use private IPs combined with static NAT rules in their DMZ.

The following gateway configuration setups are supported:

Serv-U with Public IP --> Gateway with a different Public IP with CIDR
Serv-U with Private IP --> Gateway with Public IP with CIDR
Serv-U with Private IP --> Gateway with Private IP

When adding the Serv-U MFT public IP in the Serv-U Gateway CIDR, it has to be per subnet ex. IP_address/20 or IP_address/32.

Resolution

If Serv-U is on a NATted set up, use the IP that is in the gateway’s interface therefore it is the private IP address and not the public one as seen on the screenshot below:
