Hello, tell me how to set the bitmask (https://black.riseup.net/) on whonix gateway.
If anyone has an invite to riseup.net, please share. My email - hectar@tuta.io
Or tell us how to set up VPN Debian Gateway to Virtualbox for the Whonix-Gateway. I tried could not adjust. (need the correct settings iptables or route table)
I second that 
I tried and failed at the same tasks.
Another ineresting idea would be to daisy-chain 2 whonix-gateways, one regular one (with tor) and one as vpn-gateway (vpnbox).
Like this: whonix-gateway->whonix-gateway(tor)->whonix-gateway(vpn) - but I also failed at getting this to work.
document bitmask:
https://phabricator.whonix.org/T516
user -> Tor -> bitmask -> Internet - not possible at time of writing, documented that and added a reference here:
Connecting to Tor before a VPN
User -> VPN -> Tor -> Internet inside Whonix-Gateway - discouraged due to conflicts with Whonix firewall:
Connecting to a VPN before Tor
User -> VPN -> Tor -> Internet with Separate VPN-Gateway:
- Qubes-Whonix only! Non-Qubes-Whonix is unsupported!
- Using bitmask with Qubes is not documented at time of writing.
- Connecting to a VPN before Tor
