[solved] Limit network traffic with Sanboxie?

Question

Hi all, 
 
 I'm running 5.30 on the latest Win10. I use it for having Chromium run in a sandbox, every time a new fresh browser(instance). The Chromium browser connects to a SOCKS5 proxy in the network. All work fine. 
 
 My question is: can I use Sandboxie to limit the Chromium sandbox, to only connect to lets say 192.0.2.1:1080 and nothing else? Just as a precaution, in case Chromium decides to leak traffic next to the SOCKS5 connection. 
 
 Cheers

Hi Wouter, 
 Sandboxie isolates programs so they cannot modify your host. It does not manage your network. We do have an all-or-nothing type of setting that you can use to restrict programs from accessing the internet when Sandboxed: https://www.sandboxie.com/RestrictionsSettings#internet

 It helped me in that I found https://www.sandboxie.com/BlockPort

I found that I exactly needed this. Now the sandboxed Chromium browser window can only access port 1080. Yes, on any IP instead of only 192.0.2.1 , but I'm happy with this. Solved. 
 
 Update on 22 nov 2019: Please be carefull in using this option: its broken in some versions of Sandboxie and will NOT help you block (internet) TCP traffic. Please see
