Domain config on Split Tunnel

L4 Transporter

Hi All,

I have excluded few of the domains in Split Tunnel config. I am not able to verify if the split tunnel is working curretly. If we check the route print we are not seeing any difference in the route table. Is there any way i can test this or confirm the split tunnel is working?

Also is it necessary to * before the domain? For example *protection.outlook.com or only protection.outlook.com works?

Please suggest.

Hi @Sanjay_Ramaiah ,

As mentioned here - https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000oM3WCAU&lang=en_US%E2%80%A... adding domain exclusion or inclusion will not make any difference to the routing table (except that it will add default route pointing to the tunnel, if such does not already exist).

 

Probably the easiest way would  be to generate some traffic to the excluded domain and check firewall logs if you see traffic reaching the firewall - either check traffic log, filtering by  destination IP, or URL log filtering by url (if the generated traffic is HTTP/S)
