[Users] SER behind PIX

Hi everybody.  In the topology:

INTERNET
        |
    PIX  (NAT static translate 200.x.x.2 to 10.1.1.2)
        |
    SER (10.1.1.2)

I can´t register UA from internet.(unauthorized)

The PIX is configured with the "fixup SIP" and "fixup udp SIP" commands.
I guess there is a problem when UA generates HA1 with the external IP, then 
de PIX translates this to internal IP, and the SER can´t authenticate it by 
the erroneous hash.

Anybody know some solution for it?

Thanks!

Diego
