"Many to one" outbound port rule
EthicalSecurityHacker last edited by
I noticed in my firewall logs that my computer keeps rotating outbound ports with the intent to connect on the other side with 443.
I have been doing some research, but I suspect I do not know what the search term is I need to identify the solution. The all mighty google has failed to interpret what I need to a workable solution.
I believe i'm looking to do a "many to one" outbound firewall rule.
I believe the many should be any higher range port and map it to 443.
Could this be outbound port forwarding?? Not sure if that is even a thing.
I would think I could proxy that port somehow. I feel i'm over complicating it.
I tried a rule to allow 443 to a specific ip, but it seems to be blocking since i'm not talking outbound on 443.
I tried to write rules for these random ports, but it seems to pick a different one on every attempt to make the connection (dynamic port selection).
Could someone please help me by pointing me to documentation to continue my research.
Please and thank you.
What is the end goal here?
This sounds like the way things are supposed to work.
Source devices pick a random port for each outbound connection it wants to initiate.
If I have x3 tabs open in my web brower (gmail.com, bank.com, and movie.com) my device will choose x3 random ports that look something like this:
192.168.1.11:23456 --> gmail.com:443
192.168.1.11:34567 --> bank.com:443
