Morpheusbi, Read "Carefully" the Firt Post of this Thread on page #1.
Hi HotRod, I read through your Router Problem more than once...From your description I expect the problems originate with your ISP. One reason for several different IP#s is the ISP has been changing their "Subnets". That would be caused by major Network changes within their "Backbone" structure. It sounds like they are messing around with the DHCP "Licence Renewal" as well. Most ISPs use 24/48 hours as a time span. 6 Days is something that an ISP would do to reduce the "Licence Renewal" load on their servers. If the DHCP servers give you 96 hours, the "Renew" process is updated after half of the time is used ie. 48 hours.
All of this only relates to the "External" Routable IP#s that are on the "WAN" side of the Net. Once your Provider gets their "Act" together it should settle down and likely you will have a Dynamic IP that seldom changes.

Once you are there I can update your Number on the Server.
For your internal Network (LAN) you can use Non-Routable IP#s (192.168.x.x) as described in the Linksys Manual. That part including the DMZ setup can remain the same once you have configured that the way you want it to be.
