Trying to setup ASA5505. Semi working but having issues with accessing services from the outside.
ASA5505 Basic License, Version 8.2. (plus upgrade to unlimited inside hosts).
Alert: I'm a Cisco Noob.
321.321.39.X is a place holder for privacy.
I came up with this config and tested it tonight.

The servers that had static forwards did not have any outside network access. couldn't ping google.com for instance. mail server couldn't Domain POP the Barracuda spam filter from our ISP etc.
So after doing some reading I removed the statics for 172.21.37.11, 12 and 13, and replaced those three with what's below..
static (inside,outside) tcp 321.321.39.11 https 172.21.37.14 https netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.11 993 172.21.37.14 993 netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.11 smtp 172.21.37.14 smtp netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.11 1001 172.21.37.14 1001 netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.11 465 172.21.37.14 465 netmask 255.255.255.255

static (inside,outside) tcp 321.321.39.12 https 172.21.37.24 https netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.13 www 172.21.37.17 www netmask 255.255.255.255
static (inside,outside) tcp 321.321.39.13 https 172.21.37.17 https netmask 255.255.255.255
Now the servers (for instance 172.21.37.14) could ping the outside world again. Mail started flowing (Domain POP was successful) etc. etc. But I forgot to check if webmail worked from the outside admittedly.
But the webservers at 172.21.37.17 and 172.21.37.24 still didn't respond from the outside world. Although I was able to PPTP VPN in on 321.321.39.10 (interface) which is the outside interface IP address. and it is static mapped to 172.21.37.20.
So I'm thinking there must be something wrong with NAT somewhere? no response from 321.321.39.11 to 321.321.39.14..
Could anyone look over the config and please let me know what I've done wrong? Is there something I've missed? well obviously but.. please help! Thank you.
