Hello all,
I have a DSL with a dynamic IP connected to a linksys router. I am trying to figure out how to setup a simple linux web server behind this setup. The IP seems to rotate between a list of 3 or 4 different numbers each time it reconnects. I poked around here but couldnt find a thread which dealt with this so I thought I would ask.

I have looked into serviced like dynip which will solve the dynamic IP problem, but it forces me to leave a port open for them. I am woundering if there are any known problems with this type of setup? My gut feeling tells me leaving any ports open is a possible hole. Is there a way to secure it?

I am also woundering if there is a better and safer way to link my domain to my linux box over the dynamic DSL?

Thanks for you time
