.. on xp machine I have tried to configure on internet connection in the "secondary dns" the ip:

192.168.0.36

..now ipconfig /all (the first PPP is internet connection, the second PPP is vpn connection):

Scheda PPP tin:
Suffisso DNS specifico per connessione:
Descrizione . . . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Indirizzo fisico. . . . . . . . . . . : 00-53-45-00-00-00
DHCP abilitato. . . . . . . . . . . . : No
Indirizzo IP. . . . . . . . . . . . . : 213.45.204.232
Subnet mask . . . . . . . . . . . . . : 255.255.255.255

Server DNS . . . . . . . . . . . . .  : 192.168.0.36

Scheda PPP Pix:

..when on xp client I execute:

nslookup dnsserver (name of dns server machine), on the vpn gateway:
 
[root at fw root]# tcpdump -i ppp0
tcpdump: listening on ppp0
