I have a problem in my Computers network. We have more than hundered computers in our network. When I ping from my computer to other computers that are on the same switch. Does not show any problem. But when I ping to the computers that are on the switched which are not directly connected to the same switch but are on the other swtiches. Ping replys some times and some times it gives request timeoue.

Tired having to ask to get on the internet everyday.

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.
I have 1 2611xm router and 1 2801 router. For my own lab purpose, i want to configure them back to back to support voice services. I don't know what configuration will be required at each end. in 2611xm, i have NM-2V and its also detecting the card, so i hope it will work ? also what commands i need to run on both ends .

The E1 connections has been provided by our local telco, and they are completely private. The customer is a bank, and they asking me if this is a secure connection or not. If possible, we need to guarantee that no body can get access to the bank network even if they brought E1 modem at one of the ends (telco PoP).
I searched a lot but couldnt find a clear document about connecting 2 G.SHDSL routers back to back.First of all I am not sure which type of cable (RJ11) is used for connecting two 878 routers. Does it have to be cross or straight cable.
Which RJ11 pairs will be connected each other [code]
According the configuration samples One router must be CPE and the other must be CO for simulating DSLAM.
I'm having some trouble getting two Cisco 888's to work correctly back to back.. The two routers will ultimately be used in conjunction with a BT EPS8 circuit which is effectively four wires short distance between customer sites. We have configured lots of these using the older Cisco 878's.
Anyway, as i've been struggling to get line sync on site I've gone back to basics and connected the two 888's back to back. However, I've found that no matter what I do I can only get the routers to sync at 384kbps!? And that's with a one meter RJ11-RJ11 cable.. Very strange. When we've used the 878's we get much more bandwidth. I have tried statically assigning the line rate at both ends but it still only works at 384kbps.

I followed this amazing document to understand the concept of BRI and configuration. url..but it never says if i can use the module that i have mentioned.
Q1. What cabling i need to use to setup back to back BRI using 2x 2901 routers with these modules?
Q2. What cabling do i need to use.
Q3. Is it actually possible to use these 2 modules alone to simulate a back to back BRI..?

View 7 Replies View RelatedI was having an issue with Comcast phone and internet services.Comcast had me disconnect and reconnect my modem and router. When service came back to normal one of my network connections was no longer available to me. I have two connections (one for use at my home which is a secured one) and one I use when I go to my sons home. My computer now only allows me to connect to a network called "Linksys" which may be available to the public. The connection I want to use shows up if I go to control Panel/View Network Status/Manage wireless network, and it is the first choice on the list, but the computer always uses the unsecured "Linksys". I'm afraid to do my banking over that network but I'm also afraid to start fooling with it and having no network. [code]
View 14 Replies View RelatedI have a ASA 5505 configured with three VLANs: Inside, Outside, and DMZ.I am running an exchange server on the Inside network and have configured NAT to allow connections to it from outside. This works fine. I can also happily connect to it using it's internal address from the inside. In the DMZ I have setup a linksys router to work as a guest wifi network. I configured the ASA to block any traffic from the DMZ to the internal network.This has been working fine for the last few weeks.Wireless users cannot access any internal resoureces, but can browse the internet etc.. etc..
My problem is that I want users to be able to connect to the wireless with smartphones, tablets etc..., if they do so, they can access the internet, but not get their email. From my (limited) understanding, the problem is that the ip address I am trying to connect to is the same ip that I am transmitting from. Is there any way to send the packets to the outside network and then loop them back to the exchange server?
I've got a 5520 running 8.4(1).I've setup a simple NAT: [code] Running wireshark on the outside of the ASA, I can see the packets going out fine (the source address has been translated). I can see the replies coming in from the 'net. But the replies don't get through the ASA to the internal host.What do I need to do to allow the reverse packets to get through the ASA back to the host ?
View 3 Replies View RelatedI have set up port forwarding for my WD Network HDD, which runs a Media Server (Twonky). Now, I have tested the ports and accessed it through the internet and it works fine, until... I click a link to open a folder and suddenly I get a "No such page" error thing. I have however identified this problem, it seems that when I go off the main page it re-routes to the original network address, not my IP forward address. For Example if my IP was 82.9.12.456 and the port was 800 i would go to "82.9.12.456:800" and it would load but once I navigate i go to "192.168.0.*:800/*****" and does not load the page. If i then copy and past my IP into the URL it works, but this is annoying.
