 but if ı use SSL VPN to and want to access my exchange server from VPN AREA , it does not allow me to connect. But while still use VPN ıf ı want to access with local ip of my exchange , its okay. 
 not: use as a default gateway İN VPN CONFİG if we connect VPN 
 also use firewall rule to VPN-WAN AND NAT RULE For local exchange. 
 also use firewall rule ANY TO LAN(PUBLİC İP OF EXCHANGE)AND NAT RULE for public exchange.

Hi Furkan Aracı , 
 Thank you for reaching out to Sophos Community. 
 Assuming you've created NAT rule to access exchange server publicly. Ensure that you have added SSL VPN network in NAT rule and VPN zone in a respective firewall rule. 
 After that try adding a WAN IP of the exchange server under 'Permitted network resources (IPv4)' of SSL VPN policy.
