Muiz,

It appears that the SSH and FTP connection requests aren't reaching your
firewall. From the dump:

Chain net_dnat (1 references)
 pkts bytes target     prot opt in     out     source
destination
    0     0 DNAT       tcp  --  *      *       0.0.0.0/0
0.0.0.0/0           tcp dpt:21 to:192.168.1.231
    0     0 DNAT       udp  --  *      *       0.0.0.0/0
0.0.0.0/0           udp dpt:20 to:192.168.1.231
    0     0 DNAT       tcp  --  *      *       0.0.0.0/0
0.0.0.0/0           tcp dpt:2222 to:192.168.1.231:22

Please refer to the Port Forwarding troubleshooting tips described in
Shorewall FAQs 1a and 1b.

Thanks,
-Tom
