Strange answer this one, I take it that Trev thinks the local IP address is
changing, but this is not always the case, it could be the main ISP address
that is changing and effecting the link, this is done by ALL ISP's unless one
asks specifically for a fixed IP address, normally at extra cost to you!
So the answer really, is if its, the local address thats changing then it maybe
best to set it manually with your own one but within the adrress range of the
router (if you use one) these ranges are normally 192.168.x.x or 10.10.x.x
the other answer is that its the ISP thats changing (more likely) then you
have two options, ask for a static address and pay up or setup a DNS address
that will adjust your system to take care of the change, if you want info on
this goto www.dyndns.com and read up on setting a domain name, its free, so
don't setup one that costs you, mine is http:\\gb7pfd.ath.cx, this domain
address can then be entered into Xrouter, then along with a program
downloaded from Dyndns and loaded on your system it will keep the IP address
up to date so long as people who access your system use the Http domain name.
The ISP will normally change IP's every 8 hours or so, and for normal
Interent access this is not a problem, it is however a problem for the packet
UDP network.
Hope this answers your question Pete.
