EFW Support

I have networking of  office to 6 branch office already done using leased line.

One branch office has Lan ip 192.168.1.215/24 gateway 192.168.1.1
the  office has router with Lan ip : 192.168.0.30

I have install endian efw with following settings to share internet at  office
WAN ( RED) ip: 192.168.60.2/24 gateway 192.168.60.1

LAN GreeN IP : 192.168.0.175/24

The internet is working on local clients connected to 192.168.0.0/24 network having GW 192.168.0.175

I want to have branch to  office client's connectivity using lease line and simultaneously use internet at  office client pc.

 office client pc ip : 192.168.0.165/24 GW 192.168.0.175
Branch offic client pc ip : 192.168.1.215/24 GW 192.168.1.1

i HAVE MADE STATIC ROUTE
source 192.168.0.0/24  destination 192.168.1.0/24 gateway 192.168.0.30 ( lan ip of  office router )

i can ping to client pc 192.168.1.215 at branch office from  office 192.168.0.165

i can ping to  office EFW gateway 192.168.0.175 from client at branch office 192.168.1.215

but i cannot ping from client at branch to  office client
i.e not ping from 192.168.1.215 to 192.168.0.165  ( it gives request time out )

i have added even firewall rules
192.168.1.0/24 to 192.168.0.0/24 allow all

why is that i can ping to  office EFW gateway 192.168.0.175 but not the clients inside  office

You can not ping PCs behind EFW from outside (GREEN from RED) because traffic between GREEN and RED is not routed, it is NATed.
