Site to Site with Fortigate 500D and Cisco ASA

[boozely25]

I have a site to site tunnel that is up and connecting and kind of passing traffic. 

Fortigate - Internal pc's 192.168.203.11. 192.168.203.17 NATd to 10.26.30.130, 10.26.30.131

ASA - Internal servers 192.168.50.10, 192.168.50.11,192.168.50.12,192.168.50.13,  NATd to 10.26.30.10, 10.26.30.11,10.26.30.12,10.26.30.13

In phase 2 I have local\remote addresses set to named address  _internal and _Remote

Local -  _Internal (contains two pc ip addresses) 10.26.30.130, 10.26.30.131

Remote - _Remote(contains 4 server addresses) 10.26.30.10, 10.26.30.11,10.26.30.12,10.26.30.13

the pc's can connect to 10.26.30.10 but cannot connect to the other 3 servers? Do I need to change this to subnet instead of named addresses(local Address - 10.26.30.128\25, Remote address - 10.26.30.0\25).

Also, traffic only passes from the pcs to the servers if the server initiates the traffic.

Any light  someone can shed as to why the servers need to initiate the traffic and it is not bidirectional?

Thank you
