Using dynamic DNS at SRX with non DYNDNS service provider

When placing a network equipment without a static IP address, the best way to remote access to the device is by using the dynamic DNS service. Juniper has import this feature into their network security products such as Netscreen ScreenOS and JunOS SRX.

In my low budget case, I have found an alternative way to solve this problem, which is to go for the free DNS service from Hurricane Electronic. Continue reading →
