Allow more than one ip through specific port ?
 

Friends,

I can allow only one ip through specific port like the below way :

iptables -I INPUT \! --src 192.168.0.1 -m tcp -p tcp --dport 3000 -j DROP

But Now If I want to do the above restriction for more than one IP (like, 0.1, .0.2, 0.3) and reject all other ip , then how can I write the above rules .

Plz help ... ...

You can do it using the iprange module...

...and another option could be to use the "recent" module and then echo IP addresses into /etc/proc/net/ipt_recent/${LISTNAME}. 'man iptables' (search for "recent") for details.

Block a port for specific ips!
 

Thx fukawi1...

I give the below command to enable a series of IP to nrowse using 3000 port :

"iptables -A INPUT -m iprange --src-range 192.168.0.36-192.168.0.56 -p tcp --dport 3000 -j ACCEPT"

But it is not working . using the above rules everybody can use 3000 port . But If I use below :

"iptables -A INPUT -m iprange --src-range 192.168.0.36-192.168.0.56 -p tcp --dport 3000 -j REJECT"
Then its working ,the above ip's are not connected with 3000 port for 36 to 56 ip range .

Actually I want the above first one condition where I can give the acceptance some few ip (like 192.168.0.2,192.168.0.30,192.168.0.34) and reject all other ip . Would you plz help me giving example.
I am grateful to u ... ...
