I have a strange Problem:
On my V2110 Controller I use the esa0 Interface for the AP registration.
If my AP's (Siemens AP2610) are in the same subnet, everythings works
fine. Now i want to bring one AP to a remote subnet, the registration fails, but the controller knows the new AP IP address (172.18.24.0/24). I can telnet the AP and ping the controller and the controller can ping the AP (no firewall between them). There is also a DNS Record "controller.domain.name" pointing to the 172.18.31.25
So there must be a communication between AP and EWC, because i can ping and enable/disble Telnet. But the AP is not shown in the active AP list.
I don't know where I misconfigured it.
