I am trying to buy a new UAG5100, however my supplier tells me that this product is discontinued. Does ZYXEL have any alternative? (with a comparable set of features).
You can consider both ZyWALL 310 and USG310 as the successor of UAG5100.
Here it is information of model USG310 & ZyWALL310 for your reference
Thank you for your answer, it's very much appreciated!
