[whispersystems] Signal IP addresses

["Matej Kovacic" (via whispersystems Mailing List)]

Hi,

I have Mikrotik router and for certain devices (phones) I would am
blocking all Internet access.

However, I would like to pass through only Signal traffic. So those
mobile phones will not have Internet access, but will be able to use
Signal for messaging or voice.

The problem is that Mikrotik does not support using host names in
firewall rules, at least not directly.

There is a "hack":
https://wiki.mikrotik.com/wiki/Use_host_names_in_firewall_rules

Anyway, the problem is, I need to enable access to *.whispersystems.org.
And this does not work with Mikrotik hack described above.

So, is there an IP list which should be opened in firewall?


Regards,

M.
