Can an existing lan have a connection to the internet simply by plugging in
the router to the existing switch?
The problem is that the IP address for the existing network will not work
with the Routers IP address.
Consequently I have to change the Ip address each time I access the internet
and vis versa

The inside interface of your router should be on the same subnet as
your LAN. Turn on NAT, point the workstations to the inside router
interface as gateway, and off you go.

The existing lan is through a 8 port switch, by plugging in a broadband
router/modem to the switch , I was hoping to enable all other pc's to access
the internet without compromising the security of the server.

That's a LAN locally with no ISP connection?
That;s using NAT router, firewall, av and safehex, such as

Now you want to add internet access to the LAN. Security of what server?
What sort of broadband? What kit has your ISP supplied? Cable broadband
to Ethernet? ADSL modem to Ethernet, some basic details are required.
If it's ADSL you get an ADSL modem/router, depending in ISP connection,
you may aldredy hace an ADSL modem.
If it's cable broadband, then you have a cable modem and need to get a
Cable modem compatiable Ethernet router.
You let the router do all the IP addressing, use it's NAT, Firewall
features. You set the PCs to DHCP (or all static if you want), except
for the server (whatever that is) if the server is to be reachable from
the internet, you setup port forwarding on the router to the port /
service the servier provides.
If you need more than 8 ports, you use the 4 the routers usually provide
for 3 PCs, in the 4th you connect your 8 port switch then the rest of
the PCs in the switch.
If you still don't like that idea, you can easily reconfigure (on
Windows PCs) from Internet to LAN using netswitcher www.netswitcher.com
you simply setup 2 profiles ans switch between them as needed.
BTW, on the included paste of the "Leythos" bit.
That's a repeater.
A switch passes traffic based on knowing the connected device addresses
on specific ports. SO 2 PCs hammering each other on a LAN game / file
transfer won't affect a PC using the internet connection.
Of course 1 PCs doing a DVD download from the internet will swamp the
link for all internet access. While the LAN gaming is okay :-)

If the existing LAN already has internet access and the router is connected
between the switch and the PC's then yes. You will have to manually set the
IP address of the router to a static address that works with the switch. Any
IP that is given out by the router should not interfere with the switch.
