The version of IPFilter on my server (FreeBSD 8.4-STABLE) does not support
variable definitions/substitutions else I could have used the CIDR.
My latest attempt at opening the relevant ports can be seen at
http://goo.gl/0xnhw8 but still it did not work! Maybe it's me who's getting
confused with the rules??
I have to literally leave the firewall open for Whatsapp calls to work,
which is pretty bad!
I'll appreciate any info from your contact at Whatsapp..
But also take a look at my rules and lemme know if you can act as my 3rd
eye to see where I could be missing the point/going wrong with the rules -
which are derived from http://freebsd.therek.net/handbook/firewalls-ipf.html,
to be precise.
