hi I have a virgin media box that I normally set to 'modem/enable' that provides me with a public ip address that I usually plug into my 'isa 2006' firewall.
note: I have not tried so I am not sure if I can setup 'cbac' as a firewall on the layer 2 cisco 2950, but presumably should be able to set this up on my layer 3 3550.
now I would like to know how to do the both:
question 1. what do I need to set on a layer 2 switch cisco 2950 to gain internet access ?
question 2. as I do not know the public ip address, but I could plug a cable into a server nic card and write down the ip address that does not change for a few months at least, but how would I set that on my cisco 2950 or would I set up dhcp as the public ip address provided would still come from my isp dhcp server ?
question 3. what do I need to set on a layer 3 switch cisco 3550 to gain internet access ?
note: I presume once the above can be done I would then do the following to confirm the public ip address has been detected :
- sh ip int brief
