Imac G4 connected to Airport Extreme via Ethernet to a Motorola surfboard SB5120.
Cannot fix the NAT error issue have tried the following independently
1: Mapping port TCP Port number 6881 in system pref/firewall with no change
2: Unchecking Distribute IP addresses in Airport Admin...
Upgraded from Panther 10.3.9
installed new system folder and archived old one
Had many problems since
- cannot activate airport
-cannot fully download updates(downloads thru Safari or SW update but never mounts or completes- just keeps spinning) - so I can't try to upgrade to 10.4.2...
