Ho un problema di configurazione di una VPN Pix-to-Pix tramite rete
Fastweb. Sulla rete interna ho un server SMTP, ho un unico indirizzo
pubblico e posso NAT-are o un intero indirizzo privato sul pubblico
oppure posso NAT-are fino ad un massimo di 10 porte da più indirizzi
interni sul pubblico. La mia attuale configurazione è la seguente:


I have a problem with VPN Pix-to-Pix. In inside interface of Pix i have
an SMPT server.
I have one pubblic IP and i can make nat for a number of
max ten ports (rules of my provider) from inside ip address to global ip
addres. My configuration is:


IP private port protocol IP pubblic port
192.168.1.1 http (80) tcp/udp 83.x.y.z http (80)
192.168.1.1 https (443) tcp/udp 83.x.y.z https (443)
192.168.1.1 isakmp (500) tcp/udp 83.x.y.z isakmp (500)
192.168.1.1 ipsec (1293) tcp/udp 83.x.y.z ipsec (1293)
192.168.1.1 pptp (1723) tcp/udp 83.x.y.z pptp (1723)
192.168.1.1 ipsec-nat-t (1723) tcp/udp 83.x.y.z ipsec-nat-t (1723)
192.168.1.1 ssh (1723) tcp/udp 83.x.y.z ssh (1723)
192.168.1.2 smtp (25) tcp/udp 83.x.y.z smtp (25)
192.168.1.2 imap (143) tcp/udp 83.x.y.z imap (143)
192.168.1.2 pop3 (110) tcp/udp 83.x.y.z pop3 (110)

All works well but the VPN with remote peer.

Is it necessary turn on other ports ?
What ports ?

Thanks a lot
