Hello, everyone, Currently I have the problem to build an IPSec tunnel between a PA200 (A) and a PA220 (B). My one side A has a Telekom hybrid Internet connection (its a german product with LTE and cable connection) to a Speedport router. Thus only one dynamic official IP. The other side B is a normal company connection with a fixed IP address. I have configured my tunnel so that only side A is allowed to start the tunnel. (B side enable passive mode) If I now start the tunnel on page A, I also see in the monitoring at page B the requests ike on port 500 for port 500. Unfortunately then nothing happens further and page A has then a Faild Due to timeout. You can also see that page A transmits data but does not receive any data. What could that be? What is the best way to narrow down the problem?
