iptables error in android: iptables-save and iptables-restore not working

[preetb123]

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

When i push this binary to the emulator

i can execute commands like below successfully.

iptables -L
iptables -F
iptables -A INPUT -s Google -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 Google -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 atleast the above commands they work!

but when i try

iptables-save or
iptables-restore

i get error saying

iptables-save: not found

In my config file

CONFIG_NETFILTER_XT_MATCH_MULTIPORT=m

what is the problem..?? and how can i enable full iptables functionality in android or how can i save the current active iptables rules safely and reload them when next reboot.

please help. thank you!
