User's Manual

technique of transceiving network traff ic through a router that involves re-writing the
source or destination IP addresses and usually also the TCP/ UDP port numbers of IP
packets as they pass through. EI ON refers to destination and source address
translation as DNAT and SNAT respectively.
SNAT substitutes the packet source address with an explicit I P address. In most cases,
the explicit address is one of the router network interface addresses. However,
sometimes the router address is dynamic and is therefore not known at the time of NAT
conf iguration.
DNAT and SNAT rules can be configured using the NAT menu. The setup of NAT is
similar to ACL. Each NAT entry has a list identifier, an action, a source and a
destination.
The difference is that snat and dnat rules have the “to” section, which describes an
address or a range of addresses used for substitution. The “to” section may also be
used to specify TCP/ UDP ports to put into the translated packets.
