Android iptables error: iptables-save and iptables-restore not working

I have compiled Linux for android emulator with full netfilter functionality. And I got the iptables binary after building the android from the source.

When I click this binary code on the emulator

I can successfully execute commands like below.

iptables -L
iptables -F
iptables -A INPUT -s www.google.com -j DROP

with this error:

# # iptables -L
getsockopt for multiport failed strangely: No such file or directory
getsockopt for multiport failed strangely: No such file or directory
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
#

and

# iptables -A INPUT -s www.google.com -j DROP
getsockopt for multiport failed strangely: No such file or directory
getsockopt for multiport failed strangely: No such file or directory
FIX ME! implement getgrnam() bionic/libc/bionic/stubs.c:344

but at least the above teams that they work!

but when i try

iptables-save     or
iptables-restore

I get an error

iptables-save: not found

In my configuration file

CONFIG_NETFILTER_XT_MATCH_MULTIPORT=m

what is the problem..?? and how can I enable the full iptables functionality in Android and how can I safely save the current active iptables rules and reload them the next time I reboot.

please, help. thank!
