Posted: Sat Apr 06, 2013 20:07 Post subject: Blocking all traffic except certain websites and FTP
I run 1/2 dozen laptops (wired & wireless) off my iPhone tethered to my WRT54GS.
Everything works great but I would like to block everything (all ports and websites) except specific websites and our FTP.
I created some firewall rules but the FTP will not connect. It will resolve the DNS.
Can someone see what I'm missing or have done wrong please and thanks.
I use Filezilla server and client.
FTP is connecting to "ftp.xxxxxxx.org"
Our site is "www.xxxxxxx.org"
Just posting my findings so if anyone else runs into this it might help.
After a good nights sleep, it dawned on my to get rid of the -dport on the domains. This was it allows all ports specified on that domain including the random passive ports for the FTP.
I also allowed port 53 so any systems could go directly to the DNS servers specified in the various computers.
