the question I am about to ask is pretty simple but since I've just graduated from a CCNA recently I am just a little unsure about how to acheive this!
I would like to use a Cisco 1800 series router as the main gateway in combination with a 2950 switch to provide the network foundation for a small data center which I am building.
Basically my issue is that I would like to assign public IP addresses to two NICs on a mainframe server, a Sun Microsystems Fire V480 which will run FreeBSD in combination with 'Jails' or OpenSolaris and Zones to provide a master/slave DNS setup.
Because of my lack of experience with this as I've never done it before I am wondering what the best way to acheive this is???
If perhaps I could use 2 of the switch ports on the 1800 for this and if so how? The 1800 has a layer2 managed switch built-in meaning that I could create a VLAN for the block of public IP's allocated but then if the routed port on the 1800 which most likely will be the ATM interface of the 1801, is within the same subnet the IOS will most likely complain.....
Is there anyway I can include the switchports in the same network path as the WAN interface?? Perhaps using a NAT outside definition if it's possible??
Currently I have a setup based around an 857W and one DNS server is open to the web but through NAT: http://www.optiplex-networks.com/lab/lab.html
I would appreciate any help or advice anyone has to offer :-)
Many thanks and best regards,
