What ports are allowed on your ssl vpn?

Hi 

I create a test rule and allow all ports and services.

Source VPN  - Source Network VPN subnet   - All time

Destination Any - Destination Network Any  - Service Any

Hello AHMED SHATA ,

Thank you for reaching out to the community, Please refer the VoIP documentations below:
1.) UDP time-out value causes VoIP calls to drop or have poor quality
2.) VoIP call issues over site-to-site VPN or with IPS configured
3.) How to turn the Session Initiation Protocol (SIP) module on or off

These are the ports you need for Cisco jabber clients:

I guess It's the high ports that block your audio

Hi Sir

if i select any service, this means all services and ports ?

or i must add one by one port and service as you mentioned.

Regards.

Hello,

for testing purposes it is okay to use an any/any firewall rule.

Once done, you should consider to open only those ports for te services you actualle use.

So maybe only a small number of ports is needed for your normal usage.
