    Cisco CCNA lab

    I would say that you need another router or two. In the CCNA you wont really do that much layer 3 switching, that comes later. You can also do all the routing in GNS3 as another option too.

    Dual LAN [Suggestions Needed]

    Hi zwunder, It is a real bad idea trying to have this machine on both networks, to do this properly this machine should be behind a firewall that connects to the internet facing segment. Then you should allow ports and flows that you need to connect to. If you bridge this you are exposing the secured LAN to the net, this includes adding a dual network card setup to the machine. If you could give me a little more info on the models of router/firewall that you have I can help you to design something that will be secure and give you the function that you need.

    Python Help!

    Yeah it is used to replace the %d with "%highest" and the the "d" signifies that this should be a digit.

    network puzzle

    the reason that the bridge didn't work is cause there is nothing on the windows box that I know of that will handle that ppp authenticated session. What is it about the modem that is the bottleneck, the 10/100 switch ? you would be cheaper buying a new router that can handle this for you.

    network puzzle

    you may not be able to do this in this way. It would depend on how the ISP handles the authentication on the line, are they using pppoa or pppoe?, if this is the case then you would need some kind of software to handle this, something like PFsense. what is the connection that comes in from the provider, is it a rj45 or rj11 ?
  6. There is not much to know if you only want to setup a small home network, If you are looking at Google fiber then they should give you the router that you would need. That just leaves number of ports that you need and add a wifi access point (if needed). If you are looking to get into networking as a job or for enterprise design then I would suggest looking at the CCNA from Cisco

    Way to test stability of network?

    i know that each frame would be fragmented, but how does this equate to a good stability test ?

    2nd router decreases speed.

    try this http://documentation.netgear.com/wnr2000/enu/202-10397-01/wnr2000-03-3.html

    2nd router decreases speed.

    it will use an IP to access the GUI, it will be 192.168.X.1, the X can change. The way that I would find this out is to disconnect it from the 1st router, then connect a computer, let the computer get an IP once you have that if you do an "ipconfig" on the machine, whatever the default gateway is, that should be the IP to get to the GUI. Could you let me know the make and model of the 2nd router please

    2nd router decreases speed.

    you would need to access the settings to get it to work. I would disconnect the second router and reset it to factory, then you will be able to access the GUI, then you should be able to turn off DHCP. Also the physical cabling you would need to connect a Lan port on the 1st router to a Lan port on the second.

    2nd router decreases speed.

    you would have to give me a little more info on the setup to help you more. when you say 2nd router you mean WiFi Access point right ? Also could you let me know what router that you have as if you are indeed using a router as an AP then there are a few things that we need to do to get it working right.

    That Article that you have posted is the router acting as a PPTP VPN server, not the client that was the original question, you would really want an SSL or IPSEC VPN provider that connects to the router and then supplies that connection to the users, this should be transparent to the end users.
  13. flexin1981


    I have taken a quick look at the docs online for that router that you have listed and I cant even see that VPNs are supported. May be worth just doing a quick google on that first.

    Way to test stability of network?

    I don't even think that is a good recommendation considering that ping is a singular packet Request/Response, Yes this can be a good quick test to see if get to the other side but if you are looking for stability testing we would need to see if there is loss over a TCP connection. We would need know if there is any issues in getting a series of packets to the other side without excessive loss, re-transmission, fragmentation etc. This would give us the best result in this kind of scenario. Let me ask you this question, what application these days sends a singular packet and expects just one packet back. The answer to this is NONE. Even HTTP will send more than one packet just to setup the TCP connection, that is before it starts asking for stuff.

    dam that is one big packet LOL, considering that the MTU of a typical Ethernet is 1500 and the PPP standards usually take a little off that I don't think a packet that large would even go. Also ping is usually ping is given less wight than general traffic across the internet, so I don't think that this is a valid test, I would go with some kind of real world data test like the FTP one suggested or a HTTP download test perhaps.
