## Usage
|
|
|
|
|
|
|
|
|
|
You may use different Signal accounts for different identities, such as
|
|
|
|
|
personal, work or pseudonym. Maintain the `signal` qube pristine and clone it
|
|
|
|
|
to the assigned domain, `personal-signal`, `work-signal`, `anon-signal`. If
|
|
|
|
|
you don't maintain the qube pristine, you will have to apply the firewall
|
|
|
|
|
rules manually.
|
|
|
|
|
|
|
|
|
|
Signal might loose connectivity due to [upstream rotating IP
|
|
|
|
|
addresses](https://support.signal.org/hc/en-us/articles/360007320291) with the
|
|
|
|
|
use of [CDNs to evade
|
|
|
|
|
blocking](https://signal.org/blog/looking-back-on-the-front/).
|
|
|
|
|
You will have to reapply the firewall rules eventually.
|
|
|
|
|
|
|
|
|
|
TODO: Is it worth using the firewall? If you allow all [cloudfront.net
|
|
|
|
|
IPs](https://ip-ranges.amazonaws.com/ip-ranges.json) for region "GLOBAL", what
|
|
|
|
|
is blocking an attacker from using that to host his malicious callback server?
|
|
|
|
|
Recently (2023-11-11) signal stopped working with the current firewall.
