+         This module implements an Application Layer Gateway (ALG) for
+         SNMP payloads.  In conjunction with NAT, it allows a network
+         management system to access multiple private networks with
+         conflicting addresses.  It works by modifying IP addresses
+         inside SNMP payloads to match IP-layer NAT mapping.
+
+         This is the "basic" form of SNMP-ALG, as described in RFC 2962
+
