Plz Help me in Pix 515E

hi u all tecnhocratic geeks!
i am a newbie in the world of cisco, administrating a college WAN and LAN. at a first instance i was have just two class C public Ip , one i hav given to router 2600 and 2nd for ma pix 515E outside interface. everything was going fine but recently my HQ changed ma Ip Addresses and alloted ma with 29 bits subnet. as per old prefernces i alloted one to router and one to pix and one to my database server ( new addition ). now the problm is tht my inside clients ( college Faculty ) are quite happy as they hav no prb but internet traffic to my database server ( to which i hav alloted a public ip with the pix outside interface ip as gateway ) is stopped . very strange to say tht even database server can ping the router and pix but internet traffic is blocked on it. so i m confused in tht. and wana help from all u geeks.

The route of my WAN is mentioned here

router ============> Pix 515E ===============> Catalyst 2950
thrh cross cable straight cable

one thing more tht i didt make any chage in catalyst 2950, it hav default setting.

the configuration of router and pix is given below plz consider it thorughly and give me helpful decision.
