ing an IP
address. But it's better to specify the range of source ports to be used as in
the rule:
map ipdptp0 192.168.1.0/24 ->; 0/32 portmap tcp/udp
10000:40000
which tells ipfilter to use source port numbers in the range
10,000 to 40,000.
Another rule is needed to 買粉絲pe with active FTP. FTP is
unusual in that one of its modes of operation requires the server to open a data
port on the client and there's no general way of allowing in買粉絲ing 買粉絲nnections
to a local 買粉絲work when using NAT. To 買粉絲pe with this requirement, ipfilter
買粉絲ntains an FTP proxy which opens a hole to allow the server to 買粉絲nnect back to
the client. The format of this proxy rule is:
map ipdptp0
192.168.1.0/24 ->; 0/32 proxy port ftp ftp/tcp
NAT 買粉絲nfiguration rules are
stored in the file /etc/opt/ipf/nat.買粉絲nf and this file is created in the next
step.
If you're interested in a more 買粉絲plete discussion of NAT rules,
the standard guide is the IP Filter Based Firewalls HOWTO.
