Hi,
I'am using transforming our iptables FW script towards IPTables::IPv4.
All went well until I tried to convert my DNAT rules.
Below a small test file that fails.
(I'am using IPTables::IPv4 CVS version dated 21 may 2003)
--
#!/usr/bin/perl -w
# I need the equivalent of
# iptables -t nat -A PREROUTING -s 1.2.3.4 -j DNAT --to 5.6.7.8
#
use strict;
use IPTables::IPv4;
my $nat = IPTables::IPv4::init('nat');
if (! $nat->append_entry('PREROUTING',{
'source' => '1.2.3.4',
'jump' => 'DNAT',
'to-destination' => '5.6.7.8'
} )) {
die "Append error: $!\n";
}
if (! $nat->commit() ) {
die "Commit error: $!\n";
}
and I get:
# Commit error: Invalid argument
# running iptables -t nat -A PREROUTING -s 1.2.3.4 -j DNAT --to 5.6.7.8
on the command line is OK.
Any clue ?
Thanks
alex
