Fowarding Traffic via Port UDP 53
Posted: Fri Jul 24, 2015 1:52 am
I have a Ubuntu Server in Digital Ocean , and im looking to bypass a very restrictive firewall from a known ISP , my server config is something like this
and my client is something like this :
Its a Scrambled Config
It has no problem connecting , but i cant surf the web
even if i change the dns configs in my client .
Im guessing that iptables can help me out in this , since udp53 its the port to resolve addresses in my ISP (DNS) .
Someone knows how to foward the traffic in order to get dns to work properly ?
Thanks in Advise !
