IPChains::PortFW - Perl module to manipulate portfw masquerading table.
my $masq = new IPChains::PortFW( option => value, ... ); $masq->append();
IPChains::PortFW is an perl interface to the linux kernel port forwarding facility. You must have ipmasqadm and the portfw module installed for this module to work. A kernel compiled with CONFIG_IP_MASQUERADE_IPPORTFW would also helps.
It has a similar interface than the IPChains(3) module. You create an IPChains::PortFW object with new(), you can query or set attributes with the attribute() method and you add or deletes the port forwarding rules using append() or delete().
Here are the attributes valids for IPChains::PortFW.
This is the local address from which packets will be redirected.
This is the port from which packets will be redirected.
This is the address to which the packets will be forwarded to.
