Please help to configure the router for internet connection 871W!

Hello world!

I just started styding for CCNA, so I'm totally new to Cisco stuff. Recently bought a router 871W and spent two days in a row trying to configure internet connection with no luck! I use the port console for the configs and SDM/CCP. Would be greateful if someone could tell me how to do simple configs of internet connection. I googled everything but it's still confusing. I can't assing all-IP ports FA 0-3. I used instead of the VLAN. But all tutorials use FA0 and when I try to assign an IP address to FA0 it gives me some L2 cannot be assigned or something... :/ And I am also confused at what address IP use for WAN.

I connected the cable between the Modem and the LAN of the PC port and copied some IP addresses which I think I have to use to configure the router for internet connection. And here they are:

ISP IP: 76.114.54.255

SUBNET: 255.255.248.0

GATEWAY: 76.114.48.1

DHCP: 69.252.97.4

DNS: 75.75.75.75

75.75.76.76

If you can, please help! Thank you!

Hi david,

Looks like your 871w can not get a dynamic IP address: % unknown DHCP problem... No possible allocation

you could ask your ISP to perform a reset/clear MAC add and try again?

also, kindly post lastest "show run".

Edit: just to see you've updated your screenshot. could you add command under 4

  • Please help me solve the css for font colors in this menu!

    I finally understood how to make my drop-down menu work, but I need help, troubleshooting of this code. I have fiddled with the code for several hours and were still able to remedy. My problem is that I could not distinguish between top level links and links of the menu drop down. I want links to drop-a light cream color. However, they are shown as the same color as the color of the hover.

    Here is the Web page loaded online: www.theriveroverlook.com/Trial.html

  • Helps to configure the pix firewall 507e for e-mail access

    Dear experts,

    I called our provider cisco and ask for technical help regarding our current problem as we know on our set-up.

    She told me to convey my concern to the Cisco TAC. My friends told me to post it here under discussion Netpro.

    I am writing today to ask a few questions about my pix 506 firewall configuration.

    To give the implementation Details pls find below and attached seizures of the show tech command.

    We have subscribed the service DSL and Singtel give us 2 addresses valid public IP that is 203.125.100.246 255.255.255.252.

    I used 203.125.100.246 for my external interface of my firewall pix and singtel assign 203.125.100.245 to the DSL router. In this case, we will only use PAT for internet connection.

    Currently he works very well our Mail Server is resided in the Singtel Office having the ip address of 165.21.111.22. Not work that we can receive and deliver electronic mail on the internet, and we can also surf the internet.

    Now we intend to put our mail in our own network server, because sometimes we encounter slowness on receiving and sending emails. Pls check on the IP address below

    Our LAN IP address is 192.168.1.X 255.255.255.0

    default gateway, which is the IP address of the firewall pix inside interface is 192.168.1.1

    The new mail server IP address is 192.168.1.4.

    Here's what I've done so far.

    I created a static mapping for my mail server is here

    public static 203.125.100.246 (inside, outside) 192.168.1.4 mask subnet 255.255.255.255 0 0

    and modify the access list to allow smtp on our networks.

    192.168.2.0 ip access list ACL_OUT permit 255.255.255.0 any

    ACL_OUT list access permit icmp any host 203.125.100.246

    ACL_OUT list access permit tcp any host 203.125.100.246 eq smtp

    ACL_OUT list access permit tcp any host 203.125.100.246 eq pop3

    ACL_OUT list access permit udp any host 203.125.100.246 EQ field

    Access-group ACL_OUT in interface outside

    After doing it... I have loss all the internet connection, the email does not work... so I deleted immediately. because it causes network failure.

    I have rather edit it and create a static map like this.

    public static 203.125.100.246 (exterior, Interior) 192.168.1.4 mask subnet 255.255.255.255 0 0

    and modify the access list to allow smtp on our networks.

    192.168.2.0 ip access list ACL_OUT permit 255.255.255.0 any

    ACL_OUT list access permit icmp any host 203.125.100.246

    ACL_OUT list access permit tcp any host 203.125.100.246 eq smtp

    ACL_OUT list access permit tcp any host 203.125.100.246 eq pop3

    ACL_OUT list access permit udp any host 203.125.100.246 EQ field

    Access-group ACL_OUT in interface outside

    Saw what it did not cause a failure of network or interruption. I thought that it will already work with the config, I keep it and this is the current config now... But when I change the POP and SMTP settings so that it points on 192.168.1.4 which is the new mail server on our LAN. his does not work.

    To this day, we are in a discussion with my boss or not possible to create a static mapping on our new mail server address 192.168.1.4 to 203.125.100.246 which is already assigned as external IP address and is used for PAT.

    We are asking your help to know how to set up our internal mail server statically match our public IP address that is already used for PAT.

    Please check attached the tech release see the.

    Thank you very much!

    I'd appreciate your quick response.

    Your truth.

    Dennis Pelea

    Dennis,

    Can you please send to me your configuration full pix (unscrew sensitive information) to [email protected] / * /

    I am puzzled, why this configuration does not for you. I have several clients who use a public ip address for external intf more than several other services that use this single ip address.

    Thank you / Jay

  • How to configure the router Linksys DD - WRT for WVC54GCA E4200

    I don't know how to configure the router Linksys DD - WRT for WVC54GCA E4200. DD - WRT is very complcated. Help, please! Also, I used the TZO.com to the DDNS. Can I set up the DDNS for DD - WRT router? I used the DDNS to my old model router before. Thank you.

    Hi Majekho,

    Your domain name has decided to 99.245.xx.x. If you go to www.test.tzo.com from the location of the host, you must see this IP address. If these numbers are the same, then all with TZO works correctly. I guess that it is a simple problem with ports (80, 1024) is not open in the router and forwarded to the right internal IP address of the device (for example. 192.168.1.xxx).

    In addition, if you have a DSL, you will need to call your ISP and ask them to show you how to put your modem in "bridge mode". This will disable the firewall in the modem that blocks incoming connections even if you open ports in your router.
    In addition, during the test, it is best to test on your device remotely, this is due to a common problem called loopback with most routers. For more information about looping, take a look at:

  • Configure the router WRT54G with the PUBLIC IP address and use the DHCP protocol for internal computers

    Hello

    I have a service online Internet with 5 public IP addresses.

    The router and the AP are connected to a switch.

    I would like to set up a WRT54G Router with a public IP address and use DHCP (with private ip address) for the computers that will connect to the AP.

    That the AP is connected to the switch, it is possible that the other wired computers that are connected to the same switch can get an IP from the DHCP?

    Thanks in advance

    In this case, the routing is automatic.

    Hello
