why don´t work correctly DNS, SMTP and www in PIX firewall version 6.2(2)

I have any server ( DNS, SMTP, www) in inside interface with private IP address.

With static command i traslate public address in private address:

static (inside,outside) 200.21.225.243 mail netmask 255.255.255.255 0 0

static (inside,outside) 200.21.225.247 proxy netmask 255.255.255.255 0 0

static (inside,outside) 200.21.225.245 unicornio netmask 255.255.255.255 0 0

static (inside,outside) 200.21.225.244 borges netmask 255.255.255.255 0 0

static (inside,outside) 200.21.225.242 www netmask 255.255.255.255 0 0

I configure access list to permit DNS, http and smtp traffic, but is don´t work.

?which port or service require to , to this ?

I think that http, https, www , smtp, pop3,domain (TCP), domain (udp) was enough.?

Is there any new restriction with this service?

Thank

Re: why don´t work correctly DNS, SMTP and www in PIX firewall

Can you include the access-list commands you used? Did you assign an access-group to the outside interface mapping to this ACL?

What does the PIX syslog show when you try an inbound connection? This should give you a good indication of what's going on.
