Problem cannot connect via SSL VPN

[eluser]Unknown[/eluser]
Hi all,

I have problem with connecting to my application written in php codeigniter framework via ssl vpn box(SonicWALL Virtual Office)

Application can be accessed within LAN without any problem, such as http://LOCAL_IP/myapp/
but cannot access via vpn box such as https://OUTER_IP/go/http://LOCAL_IP/myapp/

Other applications written in pure php can be accessed with the same url format https://OUTER_IP/go/http://LOCAL_IP/otherapp/

Could anybody help me on this problem?

Thanks
