airport extreme port forwarding

[jw 1]

Help Please!!!
I have fibernet (fiber optic internet) I connect directly into the wall, no router. I have my airport extreme hooked up to the internet for wireless connections and my desktop connected into the back of the (router) airport extreme.
I need to open ports
The paper work says Firewall Specifications
123/UDP:
443/TCP:
4500/UPD:
500/UDP:
4500/UDP:
I have tried every post and here I am.
Any chance of getting a step my step on setting this up?

This is what AT&T sent me


Configure the network to allow the following:
DHCP is on
MTU is set to 1492
MAC address filtering is either turned off or allowing the MAC address of the AT&T 3G MicroCell
IPSec Pass-Through is Enabled
Block Fragmented Packets is Disabled
TCP/UDP Ports
NOTE: All ports listed need to be configured for inbound and outbound connections.
123/UDP: NTP timing (NTP traffic)
443/TCP: Https over TLS/SSL for provisioning and management traffic
4500/UDP: IPSec NAT Traversal (for all signaling, data, voice traffic)
500/UDP: IPSec Phase 1 prior to NAT detection (after NAT detection, 4500/UDP is used)
4500/UDP: After NAT detection, 4500/UDP is used
