MX85 Firewall Rules

[MariamT]

Hello everyone ,

My client uses Cisco Webex  softphone on his Lan machines .

I have opened the ports :

1)  5062,8934,6970 TCP 

2)  5004,9000 , 8500-8700 UDP

3)  SIP : 5060-5070 TCP .

But the client can't make calls , but it works  when he switchs to his mobile connection .

Do you think there may be other ports that I should open on the Firewall rules ??

P.S : the ports 443 , 80 , 53 , 123 are also opened .

Thank you .

Hi @MariamT ,

Run this tool to see what ports etc need to be opened (it assesses your environment pre WebEx deployment)

Whilst it’s running it may also be worth looking at the firewall logs (maybe output to a syslog) to see what’s happening

Thank you @DarrenOC ,  I'll send that link to the client and see what we'll get .

Another way to troubleshoot that under a minute.

Take a packet capture. 

Run your tests / calls 

Sort all the conversation without any packets from B -> A ( B = destination , A  = your source client ). Which means the firewall was blocking the outbound packets.
