whatsapp on Cisco firepower on ASA

[Samer R. Saleem]

Why when i create a rule and enable a specific IP to use whatsapp on the policy applications list,it wont work?

or it would be very slow when sending text....

In order to allow WahtsApp to pass trough ASA firewall properly (inside -> outside) you need to allow:

• udp/3478

example: access-list acl_inside line 1 extended permit udp object insidenet any eq 3478

• tcp/5222-5228

example: access-list acl_inside line 2 extended permit tcp object insidenet any range 5222 5228

Also, I assume you have already allowed:

• tcp/443
• tcp/80
