Manually opening Ports from Internet to a server behind the remote firewall which is accessible through Site to Site VPN involves the following steps to be done on the local SonicWall. Bonus Flashback: March 3, 1969: Apollo 9 launched (Read more HERE.) To accomplish this the SonicWall needs a Firewall Access Rule to allow the traffic from the public Internet to the internal network as well as a Network Address Translation (NAT) Policy to direct the traffic to the correct device. interfaces.
