problem of route

Hello,
i have a problem of routing and i need help :/
Site 1 : 10.54.145.0/255.255.255.128
Routeur CISCO -> 10.54.145.1
Routeur Zyxel (Zyw 5) -> 10.54.145.2
Site 2 : 10.54.190.64/255.255.255.124
Routeur Zyxel (Zyw 5) -> 10.54.190.74

I have build a VPN from Site 1 to Site with the Zyxel Zywall 5 (

In the zywall 5 on the site 1, i have Routing table configure like
this:
10.60.0.0 / 255.255.0.0
10.243.0.0 / 255.255.0.0
10.54.240.0 / 255.255.240.0
10.54.0.0 / 255.255.248.0 /
10.54.170.0 / 255.255.255.0
10.112.192.0 / 255.255.192.0
to the cisco as gateway (10.54.145.1) to access to external site.

from the site 2, i can access to the serveur in the site 1.
My problem is that the site 2 can not access to all adresses write in
the routing table.

do you have solution ?
Thank's
