I have a IBM T23 laptop that I have reformatted and am trying to log onto my wireless internet via a linksys pcmcia card which When I try to connect it tells me I have private IP address and I am not sure how I can reconfig so that I can connect via my router to the internet.

I'm on my way of taking the CCNA Exploration, and even though I haven't got to the LAN Switching and Wireless course, one question does bug me. In your average LAN, does your average switch has an ip address, or is it a 'dumb' device like a repeater ? Is the same true for layer 2 switches and layer 3 switches or is there a difference in terms of IP addressing ? Can you even assign an IP address to a switch ? Would you want to do that and why ?

View 4 Replies View RelatedI have been assigned to create a basic IP Addressing Scheme. The company has a single class B private address range of 172.16.11.0/16 and it needs to be divided into four subnets. They are all based on a single router.
Subnet A: 500 hosts
Subnet B: 200 hosts
Subnet C: 50 hosts
Subnet D: 20 hosts
How can I subnet them correctly and how would I make an addressing scheme for each subnet? (Host range, server, peripherals, gateway address? etc.)

I am carving up an internet Class C for customer. This class C is used by 3 distinct QA, Corporate and Production firewalls. I want to carve up IP space so there is a /26 for each environment. The issue I have is the firewalls may need communication with each other via the public IP space. Currently I don’t have any L3 switches in between the firewalls and the edge internet router. So with subnetting, it would seem I need to push everything through the internet router for the intra-firewall communication.I would rather not push this traffic through the edge router, so I came up with an idea to allocate all firewall outside interface IP’s in the 4th (last remaining) /26. That way, I can allow firewalls to communicate over the primary interface IP’s, which will all be in the same subnet – without going through a routing “engine”/device.
For the actual environment subnets (NAT's on respective firewalls), I create a static route on the edge router pointing to each of the firewall’s primary IP’s for the respective environment routes (the first 3 - /26’s).This is still a beta design, but I have done this before on small scale when ISP gave me 2 subnets for example, assuming I was going to put a router in between the customer firewall and ISP. I would use the “routed subnet” on the ASA interface, and then pull the NAT’s from the other subnet. The ISP would have to add a static route directing the NAT subnet to the “routed subnet” correct IP - which would be the firewall outside interface primary IP.I recently found out that with ASA OS 8.4.3 and up, ASA will not proxy arp for IP’s not in its local interface subnet. This means the ISP/router will have to assign static ARP entries on the edge router. This can get messy after the first few NAT entries. So I am debating the design now. I think this kind of stuff going forward won’t be worthwhile with newer ASA 8.4.3 code.
How to communicate between different ASA’s, while still carving up the Class C into usable smaller subnets? The primary reason for doing this in the first place is to support routing on the edge router. I am thinking it might be time to ask for another Class C to do the routing functions, and keep the firewalls all at Layer 2 in one /24 - Class C?
I am getting ready to setup avtice/standby failover on our ASA 5520's and have run in to an issue.I currently only have one External IP address available. My Idea was to use a private/placeholder IP address for the standby external IP Address, will this cause any issues with the failover? I know I won't be able to access the secondary from the outside, but that is not an issue.

I'm starting college in the fall and will be living in the dorms on campus.

I'm looking to put together a solution for a customer that wants to "bridge" between their current office and a new office space they have rented. I know how to set up a site-to-site VPN between two sites with different private IP ranges. For example, site A is 192.168.1.0/24 and site B is 192.168.2.0/24. But is it possible to make both sites appear as a single IP block? This way, systems could be moved one by one without renumbering.I am guessing there might be a way to tunnel the layer 2 traffic and make it work, but I am concerned about broadcast services being broken. I am using non-cisco platforms so I am just looking for pointers on the protocols that might be used so I can do further research.
