GlobalProtect Gateway is being used, and all traffic is being routed to the firewall except for some network.
DNS lookup takes a long time when I input the domain (website which not in the PC DNS table) that the browser accesses first while connected to a VPN
- DNS Lookup time takes about 5-10 seconds
The DNS server is using an internal server, and the network is belong to split tunneling exceptions.
I am wondering why DNS lookup processing is delayed.
Or is it correct that DNS lookup takes a long time during VPN connection?
The issue was resolved as follows.
Cause: Querying queries to all NICs that have DNS Lookup enabled, so lookup time increases while waiting for results from VPN NIC
Resolution: Register in paloalto registry to run batch script after VPN authentication.
The script content deletes the DNS Server settings of the VPN NIC to set DNS queries to use only the primary NIC of the PC.
