some firewall / port forwarding questions for mac

[Jreifler]

Hey friends,

How do you make sure that your MAC is always a specific # on the router?
I want to keep the MAC as .105 all the time.

I'm trying to set up videochat and have been troubleshooting for a few days now.

So far....

I turned off my internal mac firewall.

In my linksys router I opened port range forward 5060 UDP, 5190 BOTH, 5220 TCP, 5222 TCP, 5678 UDP, 16384 to 16403 UDP. These are all going to port 105, which is my computer's current listing.

I had the other mac computer that I'm attempting to connect to, follow the same steps for router ports and firewall settings and it didn't work.

Finally think I realized the problem. My computer keeps getting assigned different numbers. At least I am hoping this fixes it.

Any other troubleshooting suggestions?

Thanks for your help!

Did you follow all the instruction on this page for firewall ports? Also keeping the same IP number from you router is fairly easy. You first have to read your router's manual to see how to set internal static IPS or static DHCP IPs. Then on you OS X machine open System Preferences->Network and configure your ethernet for either "Using DHCP with Manual address" (for DHCP static IPs) or "Manually" for a full static routing IP.
