SSLVPN to S2S, Source IP

[Chura]

Hi, I' m configured on my 1500D with SSLVPN Web Portal only (No tunnel mode). Using ' Native RDP' widget i' m trying to access DRP server behind S2S. Since the client doesnt really hold IP in my network, i see that the device trying to use the first available IP as source for this session, which is my MGMT interface . I' ve tried to look for confuration that tells the FG what IP to use for such actions (For instance, i' m using FAZ on the other site and there I can choose source IP) Thanks Chura
