Whitelist External IP By Port

post #1 of 4
Thread Starter 

Hello everyone,

 

I have a specific port on my router (DD-WRT) that I would like to whitelist, I only want certain IP's to be able to to access a port.


I have tried looking online and I haven't had much luck/understanding what it would take to do that. I would like it to reject(?) the connection, so basically you don't even know that it even existed.

 

I'm sorry if it doesn't make sense of what I'm asking, I'm just having a hard time trying to convey what I want.

 

Thank you in advance!

Be Rock Steady

You can do this with DD-WRT, I have mine set up to accept WAN connections from two VPSes. If you port scan or try to connect from other WAN addresses the port doesn't even show up as closed ('stealth' instead, indicating no reply at all received).

You can specify CIDR address ranges, as well (e.g. xxx.xxx.xxx.xxx/24). I used to do that so that I could access SSH at home from school, but not from anywhere else.

Thanks guys, I had the port forwarding setup but I didn't know the Source Net would cause it to essentially white list. +Rep to you all.
