| getting my hand wet over cisco!! please help Hi all, let say that i got a configuration on this forum to launch home network. For this purpose i bought two transciever and the appropriate cable. Now my problem is that after i key in the configuration and save it in my router 2514 i don't know how to connect to the internet. I usually click on my dial up DSL to be connected but now when i do that i got no response. But i can see from my router that something is happening but i don't know what!
Now !is there a special setting that i should do to have my pc able to get me connect to my router? For those who can understand cisco this is my configuration:

From all this information can someone guide me through please. I have been stuck with this issue for at least 3 monts now and i like to learn, know and understand this cisco stuff. Any help will be appreciated. In particular when you have the modem connect through the transciever on Ethernet1 and on Ethernet0 i have a transciever which is connect to the ethernet port of my pc. and i have key in and save my configuration now what else i need to do so that when i open explorer i will see that i am connected to the internet? |

kudos:1 | Add this command Try to add command "dialer-list 1 protocol ip permit" and see what happen ...  |

Re: getting my hand wet over cisco!! please help What kind of cable are you connecting to the PC with
straight-through or crossover? You should be using a crossover if its connected directly to the PC. |

I am using a cross over cable. However after reading a post by a member it is state that you need a tftp server. this is what he develop:
I REPEAT THIS IS NOT FROM ME BUT IT IS AN EXAMPLE THAT I FOUND ON THIS FORUM!
**************************
A)For illustration purposes, I use:
* Cisco 806 router
* ISP provided static IPs
* ISP provided DNS
* PPPoE (have to put username and password to connect to ISP)
Also for illustration purposes, I run FTP server behind the router. This configuration can be modified to also have web or mail servers.
Just a bit of explanation. E0 interface is for inside network (LAN). E1 is for outside (ISP or WAN). Dialer1 is for PPPoE. The 1.0.0.13 is ISP provided static IP address for the use of the server. This configuration example is for running FTP server, which uses the standard port 20 and 21.
The LAN uses 10.10.10.0 network with 255.255.255.0 subnet. All servers in the LAN use static IP address.
Basically I suggest that you deploy NAT (Network Address Translation) and PAT (Port Address Translation) to setup your own servers behind Cisco router. The NAT is used to translate the ISP's given static IP address to your local IP address. The PAT is used to translate TCP ports (the port 20 and 21) between the two IP addresses.
Instruments used in this illustration are pretty much standard for running your own servers. Please note that IP addresses, username, and password are changed. However, you could always modify the configuration to suit your situation.
SO MY QUESTION IS SHOULD I RUN A TFTP SERVER AS WELL IN ORDER TO BE ABLE TO LAUNCH EXPLORER AS EXPLAINED? |

i have added the command :
dialer-list 1 protocol ip permit
and i can still see nothing !
in fact when the configuration is done and the modem is connect via the transceiver on ehternet1 and ethernet0 is link to the pc port what should then happen? let say when that is done if i open explorer could access the internet, or do i need some extrat thing? if someone as got this type off setting please help out. I think norezo did say on this forum that he succeded building such network connection with his router 2514. It is the same issue that i have now. i have finish the hardware connection now i don't know how to do to get the whole thing working. |

again i need to ask this. i got only one pc and one router 2514 load with ios 12.3 and 2 transceiver + 3 cross over cable. I have connect the port ethernet0 to the pc and ethernet1 to the modem. i have also configure the router with the above configuration that i save in my nvram.
Now i don't know what to do next because i thought that after those step if i click on the explorer icone i can be connected to the net, but it is not the case! so i know i am missing something. Normally i can do without the hassle by connecting directly my modem to my pc without the router. But i want to learn so i though of giving this connection router+modem+pc a try!. Can someone tell me if i need more stuff or if i am missing something please. The whole thing is driving me nut because i been on this problem for months and i just realized that without outside help i will never gonna be able to do it.:o:o:o:o:o |

It seems like ur connected since you do get an ip address. I would say try pinging your DNS servers or google.com or something, If you get replies then make sure u set the DNS servers on your PC. Other than that im not sure what the problem could be.
One more thing, try sending it through a switch instead of directly into the router. |

Clarification and suggestion After I revisit your config, there are some things that are incorrect. 1st of all, let me clarify something.
1) Does your ISP require you to use PPP (specifically PPPoE)?
2) Is it the IP address of 81.56.167.167 the proper IP address the ISP gave to you?
Assuming answers of above questions are all true, you cannot use 81.56.167.167 (or any IP in 81.56.167.x range) for LAN interface (e0). Why? Because you perform NAT. You have to use different IP segment (private IP address recommended).
The example on the FAQ stated, it used 10.10.10.x (10.10.10.1 255.255.255.0 to be precise) as IP address of e0. Now for the sake of simplicity, do the followings:
1) Replace the e0's IP address with 10.10.10.1.
2) Modify "access-list 10 permit 81.56.x.0 0.0.0.255" to be "access-list 10 permit 10.10.10.0 0.0.0.255" to match the modification on the step 1.
3) Add "ip tcp adjust-mss 1452" under interface e0's config to match the interface d1's.
4) Replace your PC's network setting with the followings. Set the IP address as (let's say) 10.10.10.2 with subnet mask 255.255.255.0 and IP default gateway as 10.10.10.1.
5) Lastly enter the DNS IP address (or addresses) to the PC's setting as well. If you don't know, ask your ISP; or see if you can find and use a working DNS.
Try these steps and see what happen ... |

| ok , i am giving it a go. i shall let you know in lets than an hour. Other than that the address that was giving to me by my isp is: 81.56.167.167 and you can verify it by looking at my ipconfig /all

Re: getting my hand wet over cisco!! please help Thanks aryoba, i follow your advice and now i am connected!!!!!!, everything start to make sense now to me! i have been the biggest idiot to believe that i could have use the fix ip address to configure my interface e0. But thanks to you i learn my lesson. I can think you enough, ss you man i am now enjoying a bit of my investment. many thank and have a great week end. |

kudos:1 | Yay! We did it! You're welcome! Actually I should give the advise at the 1st glimpse. This is what happen when I am in a middle of something.
FYI, instead of using the private address 10.10.10.x; you of course can use 192.168.0.x like the one you show. But I always like to use 10.x.x.x for PC's network settings and use 192.168.x.x for routers (or layer-3 capable device) for the sake of OSPF.
I hope we all can learn something here. And emidika, you might want to document this thread for future reference, in case you lost the config or face similar situation.
I always like happy ending ... |
