NETMAP for the local and remote network
In this example, the NETMAP rules from NETMAP for the local network (Page 206)and from
NETMAP for the remote network (Page 211) are combined. There is, however, a special
feature with the outgoing queries. With outgoing queries, whose source IP address is
translated from 192.168.20.0 to 192.168.200.0, they can have both the IP address
192.168.10.10 as well as 192.168.100.10 as the destination IP address. The rule for
translating the destination IP address requires a further NETMAP rule. The addresses are
translated by the M876
② and forwarded to the destination ③.
With the incoming query both IP addresses are exchanged.
al network > remote network:
The source IP subnet 192.168.20.0/24 is replaced by 192.168.200.0/24.
The destination IP subnet 192.168.100.0/24 is replaced by 192
.168.10.0/24.
With queries with the destination IP subnet 192.168.100.0/24 the source IP subnet
192.168.20.0/24 is replaced by 192.168.200.0/24.
