What IP Ports and Protocols do ADOTs VPN system run on?
ADOT uses IPSec (IP Security Protocol) exclusively. If you are trying to connect to ADOT’s VPN System and there is a firewall between your computer(s) and the Internet, the following bidirectional “allow” rules must be added to your firewall to allow the secure traffic to pass. Authentication Header (AH) is not a required protocol. Host: 184.108.40.206 IKE (Internet Key Exchange) UDP Port 500 ESP (Encapsulating Security Protocol) IP Protocol 50 NAT Traversal – Network Address Translation (NAT) is commonly used on small office/home networks when a router/gateway is deployed. If your network uses NAT, create a firewall rule to allow this feature, in addition to the rules specified above.
