I have installed an SA520w as our office side gateway and users are continually getting dropped connections when trying to use RDP to our terminal servers. Thing is, they are not going "through" the device, it's just their gateway address, and from there the hop to our internal 4503 router to get to the terminal servers. When I put the 1701 back in place instead of the SA, things are fine. Users just basically "bounce" off the SA to get to the internal network. To top it all off, when I go to the administration tab to check settings, I get logged out saying the session has timed out. I cannot do anything with the device. I have upgraded firmware to 1.1.65 already...what is left to do?
