24 Hours of Leopard: Back to My Mac

I have the following network configuration at home:
DSL modem connected (wired) to an airport extreme which transmits signals to an airport express with bridging configuration.

My iMac and iBook are communicating with airport express for internet and music. Back to my Mac works within this network. However from other place I cannot connect to my iMac (iMac is not sleeping, .mac account is the same).

How can I activate NAT for this configuration to be able to use Back to My Mac from other location? Is there anything else to try?

Hello. I can use back to my mac with no problems when i am using in the local lan when i try to use it from an external mac it don´t shows up in the finder sidebar. Can anyone help me? Back at home i have an imac with an Airport extreme connected to a D-Link DSL-G624T. Is there any configuration that i need to put in the dsl modem?

No, there is not a .Mac for corporate environments. They have a single-user account and a family pack that includes several sub-accounts, but nothing that would be appropriate for a corporate environment.

No, you cannot get BTMM from a Windows machine on the road, it's only Leopard-to-Leopard.

I've only been playing with my Leopard installs for about an hour now, but I'm loving the fact that this feature lets me run my media server headless without the lags and dropped connections I always got with VNC clients. Not the most useful part of Leopard, but it's a nice little bonus for people like me.

Doesn't the "Wake for Ethernet network administrator access" option in the Energy Saver pref pane serve as a Wake on LAN option?

Can you get back to your Mac from a Windows machine on the road?

Any idea how this will work for someone who wants to remote control someone's mac without using iChat (i.e. just remote in without them signing into ichat and accepting a screen sharing invite)

Also, how will this work for multiple clients? My company supports many mac users, and we all have them on logmein, we can see all the computers in one list and remote in whenever we want.

Is there some type of .mac for corporate environments?

#9 -- Luigi, not sure what you mean by "a NAT thing." You need to have an Internet connection, and if it's behind a router chances are NAT is active. B2mM will work over some connections, not over others -- you'd have to try it and see.

You could just set up a VNC client, but you'd also need dynamic DNS (to keep track of the home IP address), file sharing, and possibly a VPN tunnel as well as pointed out above.

I need to know... do you NEED to have a NAT thing? I could never figure out how to set it up...and if ya did need it, why wouldn't you just you a vnc client?

#7 -- Rob, thanks for the alternate solution, interesting points on encryption and VPN; I think you're missing the B2mM point though.

a) Your solution, though technically superior, requires a level of sophistication that might just be outside the comfort zone of some (not to say most) Mac users. :-)

b) This isn't the only reason to get .Mac, so "expensive" is a red herring. Yes, .Mac is expensive compared to putting together all the features yourself, but (speaking for me) my time is valuable enough that $100 would not compensate me for the 8-24 hours I'd spend cobbling all the functionality together.
