Palo Alto VM No Internet in Browser

L0 Member

Hello,

I have PaloAlto on GNS3 i set a policy from inside to outside and i also do the NAT policy Plus the virtual router configuration.
from inside i can ping to internet but i cannot browse, is that related to licence or i miss something?

Thanks.

Did you do any policy trace as you may have allowed just the icmp and not web-browsing  or SSL (if you don't do decryption Palo Alto will see most applications as just SSL)?

Thanks for your reply, i allowed all services not only icmp.

You may also do policy trace for the NAT and check if you are using SSL decryption as if it is not configured corectly you may see issues. I suggest also doing pcap capture at drop and transmit stage as to see if the firewall is droping the traffic or not transmitting it as it could be GNS3 issue. I have made an article in live palo alto for such checks if the issue really is because of the firewall:
