Re: How to configure dynamic DNS client?

The way you describe it, your entire network is available to internet
including any file sharing you are doing. Is this a business and is this
what you want?  I really don't think so.

You should consider reconfiguring your entire network .. something like
this:

====<DSL>===[DSL MODEM]---->[RH eth0]
                            [RH eth1]--->[10/100 switch]
                                         /     |    \
                                        /      |     \
                                     [PC1]   [PC2]  [PC3]
Obviously Verizon allows you to pull more than one IP address but
because of the frequent disconnects you will always have problems.
