This is my topology I have configured Clientless VPN hosting two application as, paloaltonetworks.com (external-application) and amazon.forest.in (internal hosted application). But i am unable to access the application that hosted inside. In this question have attached my configuration also. other than that there is no sent byte for clientless-VPN traffic also.
ISSUE NOTE : 1.External Application working but there is no sent bytes
2.Internal Application not accessible
This sigfnals a routing issue or DNS issue as 0 bites are send. Check if the DNS resolution is working for the Palo Alto as maybe the routing or Service route is wrong (palo alto by default uses the managment):
Also check the config:
Finally just check the global counters, tcdump for drops and the security policy:
Also there are a lot of articles for debuging web issues for clientless vpn and try using different browsers:
Hello, Did you test the DNS resolution and routing are correct ? If so using another browser as your error seems to be seen a lot for chrome browser and then finally doing tcpdump/pcap capture for the rewrite action to see how Palo Alto rewrites the HTTP/HTML content and you can find this from the links I shared and also using Fiddler to see how direct access to application looks like without the Clientless VPN and with it and to compare.
