Hi

im running 841nd as dump ap and running openvpn client.

i only have one device connected to it ( 192.168.1.66 ), but i have lots of requests from other lan ips.

tried everything to block but nothing works.

example:
IPV4    UDP    192.168.1.66:4097    209.209.209.209:53713    1.83 KB (28 Pkts.)
IPV4    UNKNOWN    dsldevice.lan:0    all-systems.mcast.net:0    1.69 KB (48 Pkts.)
IPV4    UDP    192.168.1.81:138    192.168.1.255:138    229.00 B (1 Pkts.)

how can i block ports 53713 , 138, 137 using iptables ?

the ideal solution is only allow ip .66 use ports 443, 53 and 80 nothing more.

thanks
regards

On a "dumb AP" as described on the wiki, traffic does not go through the firewall (which, according to the recipe, would actually be disabled).
