I'm pretty sure this doesn't belong on serverfault. Anyway, I'm confused with DynDns. Its supposed to change the IP address whenever your IP address changes, but for anyone to access the host I have to make it point to my router's global IP address, which I have to forward port 80 to my computer's current local IP Address, and the port forwarding won't automatically change when the IP address changes. Any help? Thanks. By the way, I'm on an iMac, with Aiport Extreme (AEBS) router.
Ohh Its the global router ip that changes, that dyndns deals with? Ohh ok now I understand.. But I don't think I need to make the local ip static because Airport Extremee always tries to use the same IP, so far the local IP for my mac has never changed. – mk12 – 2009-10-15T02:26:14.463
1If you never have any other device come onto your network, you will probably be okay. However, if you have more than one device on your network that gets its address from DHCP you could get assigned a different one. It may not be likely, but possible. – heavyd – 2009-10-15T02:29:59.213
+1 deleting my answer it it essentially duplicates what you say but with less detail than in here – A Dwarf – 2009-10-15T02:41:12.300
Actually, it's Chris who does. +1 there too ;) heavyhead answer is just as good though – A Dwarf – 2009-10-15T02:43:32.077
Yes, it is definately using DHCP, and I also have 5 other devices that connect through the router via WiFi. – mk12 – 2009-10-15T19:53:29.227
Then I would suggest putting your server on a static IP outside of the DHCP range of addresses to be sure that the server doesn't end up with an IP that you're not forwarding to – heavyd – 2009-10-15T20:16:47.120
please see my new question regarding making the static IP outside of DHCP range -- http://superuser.com/questions/55930/how-make-static-local-ip-for-server-on-os-x-airport-extreme.
