dynamic dns?

[xSauronx]

id like to use dyndns so i can have easy remote access to my debian box at home

both my dsl modem ( a zyxel 660r) and my router (buffalo flashed with dd-wrt) have dynamic dns clients built in, so getting that part done is simple enough (and, indeed, done)

but what do i need to do to be able to use ssh from another location to get to my home box? forward ports through my router is, i assume, a necessity, but what else?

the modem has a firewall built-in that seems quite basic, will i need to change anything, or turn this off?

any pointers to get me started are appreciated 🙂

Yep, all the ports that are needed for SSH and your remoting need to be open on the router and set to foward to a specific IP. I would do some port checking with a tool to see if the modem firewall is blocking those ports or not, to determin whether or not they need to be changed.

As an FYI I sometimes have issues with the router updating Dyndns, not always but sometimes it doesn't. Which its not that big of an issue since it doesn't cahnge alot.

search the forum for remtoe desktop, prettty much all the same pointers in them

This might indicate that your Modem is actually a Modem/Router combo.

It could be that Just disabling the Firewall does not open all the ports.

Many of these combos are very particular in the way they work.

If this is the case you should try to open ports in the Modem/Router and configure the second Router as a switch py passing double Routing.
