Hi @Yasar2020  It really depends on the internetactivity. In my case we had situations where our 5050s were exhausted with 250mbps of internet traffic. The sessioncount I think was somewhere arount 18'000 concurrent sessions with about 12'000 decrypted sessions (it's already a while ago since I replaced them, so I am not 100% sure if I remember correctly). But with more and more websites offering decryption with stronger algorithms, the 5050 will probably have even faster not enough computing capacity for tls decryption. Without decryption the 5050s are probably still fast enough, but you cannot go higher than PAN-OS 8.1 which is also a point you should keep in mind when using these as internet firewall. ...

Hi @Yasar2020  Prior to propose a migration procedure, are you going to use the 5050 for ssl decryption and if yes, how many users internettraffic should be protected by this firewall and what internet bandwidth do you have? ... View more

In this case please open the website again but this time with developer tools opened in the browser and then go to the network tab. There you should see if some requests are failing. For further help here I kindly ask you to provide some more screenshots (network tab of the developer tools, security policy, logs on the firewall). ... View more

Hi @Joshan_Lakhani  I see two possibilities to do this: Configure the DNS proxy feature to only correctly resolve this one dns entry you need (the client/server then needs to have this dns proxy IP configured as DNS server) Create a custom application signature where you specify the DNS entry that you want to allow ...

Hi @raji_toor  You now reached a point where it is at least possible, that something on the firewall ist not compatible with the F5. So at this point I would recommend to open a support case and then continue with the following troubleshooting (these logs will also be required in the support case).  Obbiously you need to change the IPs and maybe also the port, depending on your configuration clear counter global debug dataplane packet-diag clear all debug dataplane packet-diag clear log log debug dataplane packet-diag set filter match source 1.1.1.1 destination 2.2.2.2 destination-port 443 protocol 6 debug dataplane packet-diag set log feature proxy basic debug dataplane packet-diag set log feature flow basic debug dataplane packet-diag set log on debug dataplane packet-diag set capture on Then you connect to the VIP with decryption enabled and right after that enter the following command. In the output, maybe you already see a specific counter which could lead to the reason of the problem show counter global filter packet-filter yes Try to connect a second time and then stop the logging and capture debug dataplane packet-diag set log off debug dataplane packet-diag set capture off Then aggregate the logs. The output of the command will show you the filename that you need to analyze debug dataplane packet-diag aggregate-logs Prior to analyze the logfile start now with generating a techsupportfile (for the supportcase) Maybe for analysis you want to copy the logile away from the firewall to open it in a texteditor but of course you can also view it in cli. About here I don't know what to do exactly, I would scroll through the logs to find something that maybe shows the reason why the TLS handshake fails after the client hello.   ... View more

Hi @Marc.Luecke  What OS version do you have and what TSA version do you use? At the time when this happens, did you check the allocated ports for this user? Did he maybe reach the 200 ports? How many users are connected to that server? Did you verify if the connection on this port really is from that user that tries to download something he should not be allowed? ... View more

Hi @raji_toor  Yes, I think you are right with this conclusion. But besides that I would recommend anyway to configure some stronger ciphersuites on the servers, you could give it a try with enabling 3DES in the decryption profile via CLI. I did not test it with an actual inbound decryption, but I was able to enable 3DES with TLS1.2 in CLI. On the WebUI then it does not even show 3DES enabled but in the configuration it is there. ...
