On your Firewall, you have specified the default Gateway as the same Address you specified for the external interface.   They cannot be the same.  

Plus, from your definition, it seems that you have the same subnet defined for the internal and external nets.  

Internet 203.194.128.xxx
|
(External IF)
ZyXel External Modem
(Internal IF 192.168.1.1)
|
(External IF)
Firebox 700
(Internal IF)
|
Switch
|
Server 192.168.1.10


If you look, you have the same subnet (unless you are subnetting but I doubt that) on the outside of your firewall as you have on the inside of your firewall.  THis is a no-no.  

Try assigning as follows
Internet 203.194.128.xxx
|
(External IF)
ZyXel External Modem
(Internal IF 192.168.1.1)
|
(External IF) 192.168.1.2 SM: 255.255.255.0 GW: 192.168.1.1
Firebox 700
(Internal IF) 192.168.2.1 SM: 255.255.255.0
|
Switch
|
Server 192.168.2.10 SM: 255.255.255.0 GW 192.168.2.1

Good luck
