Configuration Of Internet Leased Line?
Dec 28, 2011
I got following IP address from BSNL to configure Internet leased line.OFC cable was terminated at our premises. it has to connect Ethernet port.Say eg.Wan IP : 192.168.1.6 255.255.255.252Public address pool : 172.168.10.6 to 12if i configure one address on Ethernet port1 as nat outside 192.168.1.6 255.255.255.252.the ip address given for wan & pool are different.Then how can i configure pool and how to configure nat inside eg 185.168.10.1 to 255the above ip are not actual ips just given for example.

I have configured cisco 1751 router for internet with nating. Internet browsing working fine. But We have polycom hdx 6000 conference system to connect from remote site.
1. While calling remote ip it is ringing and connecting but not displaying any thing on the screen but their side is displaying.
2. When they call our side ip it cannot connecting.
I have connected netgear router then video conference is working fine (with out port forwarding also). If I configured that router between 2 local sites (not on internet line) its working fine where i did not configured any thing just given routing. Configure same situation using internet leased line.

The reason is i want to know the difference between the leased line and the DSL line. The whole thing behind the confusion is, We plan to have a high speed internet connection in our office. We will don't have a branch office or some thing like that. I preffered to have high speed internet in our office. I found in some website that Lease line will have high speed connectivity(Upto 10Gbps). Can i use the lease line or DSL is enough for our office. Our office contains of 82 user who will use internet.

I have a cisco 2911 set up at one of my sites and it is configured with sub-interfaces as this provides a default gateway to each of the offices.I have just had a 100mb leased line put in and i have a couple of questions regarding the config.let me start by telling you how it is set up .I have 3 HP Procurve switches connected together then that connects to the Cisco and the Cisco connects to a Zywall
HP Switches > Cisco 2911 > Zywall > Internet
We are wanting to remove the Zywall and connect the Cisco to the Leased line box
HP Switches > Cisco 2911 > Leased Line > Internet
The config of the cisco is
G0/0 - is up but no cable connected as this holds the sub-interfaces
G0/1 - Connects the Zywall - 192.168.1.1 (this has firewall rules to forward traffic through)
G0/2 - Leased Line
The way i have configured the sub interfaces is with its own DHCP pool and default router, some of the offices have there own ADSL router and hold there own Internet connection and the default gateway for that is 192.168.xxx.253 and the offices that use the Cisco use default gateway of 192.168.xxx.254
Now my question is how would I move everyone onto the Leased line and get rid of the Zywall ? Would it be as simple as giving the leased line an address and put in a static route to forward all traffic through that connection ? Or am i missing a trick or 2.

Leased line is between dammam to dubai and the dammam office is getting internet from dubai.The ip address of Dammam office is class A (Public IP) x.x.x.x and for dubai it is y.y.y.y which we are using as proxy for accessing internet.I purchase the local DSL direct line connection through cable from Local Provider and this ip address range is 192.168.1.0 - 192.168.1.254.Is it possible to use the DSL line as failover, so if one line goes down the user should remove proxy and can use local internet.The router which is using is cisco 1800.
I believe that failover is possible, 100%, but would like to know how I can do it and requesting for sharing more inputs about failover in this case.

I am going to design one network. I had queries with this design.Let me explain scenario first( it was attached below).I have two sites, Site-A and Site-B, repectively.
In site-A i have one Cisco 1841 router, one Cisco ASA 5510 firewall and One cisco 3560 layer 3 switch.
in site-B i have one Cisco 1841 router, one Cisco ASA 5505 firewall and One Cisco 3560 layer 3 switch.
From ISP side
I have point-to-point leased line between sites A and B. And both sites have internet connectivity from another ISP.
I planned to terminate leased line in cisco 1841 router in both branches for branch to branch connectivity.
I will configure site to site VPN between two sites, A and B.
Here my query was i want make VPN as failover connectivity if leased line fails. In both the cases, i need internet to the inside users in both sides.
Summary requirement:Leased line is Primary and VPN is Back-up, if leased line fails. In both cases internet is needed to inside users.

I have two sites connected via 2901 routers to a head end with an ASA 5510, the WAN circuits are LES running at 100MB and at the head end we have a 100MB leased line. All WAN circuits are provided wires onlyby another supplier. I have setup the two 2901 routers with inside IP addresses on GE0/0 and a /30 subnet for the GE0/1 interfaces to the ASA over the LES circuit.
The LES circuits are set to 100MB but the problem I am having is that one of the 2901s will only negotiate at 10MBps Half Duplex with the ASA at 100MB Half Duplex, the other will negotiate at 100MBps Full Duplex at both ends. My WAN provider tells me both LES circuits are the same so I cannot work out why one will negotiate at 100MB Full and the other at only 10Mb Half.
At the head end I have and ASA 5510 connected to the WAN providers 100MB circuit but testing from my end sites I can only get 6MB download and 0.5MB upload on an Internet Speedtest.
I used Wireshark when downloading from my end sites and I can see lots of TCP retries and duplicates so I think this is a duplexing issue, my question is, my WAN provider is stating the issue is nothing to do with them and it is my 2901 and ASA that is at fault, they state if they connect a laptop to the LES circuit and then their leased line they get 100MB up and down.

I am a total new comer for Cisco Router. All I know is plug the console cable to a serial port on a PC, fire-up HyperTerminal to view and that's it. I don't know any command or scripts.
I am trying to setup my client connection, I already receive the required configuration settings from ISP. It is a Leased Line Serial connection.
How to setup the router with the below configuration.
Serial IP : 1.X.XX.222
Serial Netmask : 255.255.255.XXX
LAN IP : 1.X.XXX.1 to 1.X.XXX.31

We plan migrate an old existing WAN architecture based on legacy data serial links. These links will be consolidated on a E1 channalized card.
My question :
Is the HWIC-2CE1T1-PRI need a PDVM DSP ressources on router to oparate for data leased lines or no?
The VWIC3-1MFT-T1/E1 will be used for the backup dial in ISDN connexions? this type of cards a PVDM DSP ressources for data connexions or no?

NTP server When I setup NTP server to take time from [URL] everything is working fine but as soon as I reset my router during boot I can see that router is first trying to get time before it's even connected to ATM and when it can't get time from NTP server it's removing NTP line from configuration (ntp server uk.pool.ntp.org source Dialer0 ). How I setup to wait with sync and do it once ATM connection is up and established? Or How to get IOS to leave this line and sync with NTP every 10 min)?

I have remote access as I work at home on a government laptop that has Entrust( for security). My IP lapse time is set for 1 hour and every hour I am losing full connection due to having to sign back into Entrust. I need to be able to lenghten my lapse time on my work computer. My other two personal computers are fine with 1 hour as there is no Entrust on either of those laptops.....is it possible for me to change the lapse time to say 12 hours, 1 weeks, whatever??

My current setup.
Layout:
Line01 Line02
| |
Cisco 2951 Cisco 2951

Cisco 3750G - Server #1 & #2 for domain controller, sharepoint, etc
|
---------------------

Cisco 2960 Cisco 2960
| | | | | | | ... | | | | |
workstation #1, #2, .... #70
And I would like to ask some opinion on the best configuration for the above layout:
1. Configuration #1 - Using load sharing and automatic failover So I want to ask whether there's any link/url that provides details/guides on how to setup the load sharing and failover?
2. Configuration #2 - Workstations 1 - 35 will be routed through Line01 gateway and workstations 36 - 70 will be routed through Line02 As for this configuration, it's done now. However, I want to know whether there's any software (preferred web based application which allows me to change the gateway from line #1 to line #2 for all 70 computers instead of having to go to each workstation to update the gateway).

I've got a problem with my phone line which is preventing me from connecting to the internet.In my house we have a phone line (Provided by Telstra) and Internet (provided by TPG)Recently at 7 at night all of a sudden our internet dropped out. I did some checking around and look at my modem and the DSL light refuses to light up.I disconnect the phone and modem separator and plug the modem in directly to the phone line. Still no DSL connection.When i connect the phone directly to the phone line (and when it goes through the seperator) it still works, but i hear strong grainy static through the phone.

We have Comcast cable (I believe) and it comes into a modem. The modem has a line out to an ethernet switch. Coming into the E switch is a line from the Upstairs router (Realtek PCIe GBE).I want MY computer to be completely private from the rest of the family, and be invisible if someone were looking. (I'm mom and I keep my frustration journal on my Microsoft Word). I don't want to use wireless.
So, I bought a Belkin N150 and put it between my computer and the switch, and the internet didn't work at all. However, if I use a line that comes from the Realtek router, it works. I am SO confused! (I found out that if you are hooked to the same router as the others in the house, they just have to be smart enough to configure that router and they can see everything you do on your computer!)

I'm trying to configure policing and/or shaping on a setup of 2 x ASA 5505 Sec Plus. The units are placed in office A and office B and each have a ISP connection to the internet and a leased line with a capacity of 4/4 Mbit/s for interoffice communication.
On each ASA there's four subnets. VLAN 200 is used to connect the offices through the leased line.
Subnets:
Outside = 2
Data = 10
Voice = 100
Linknet = 200
I've read a lot of articles and posts about shaping and policing on the ASA but still can't get it to work like I wan't to. I'm trying to limit all traffic besides IP-telephony traffic to 3 Mbit/s and thus reserving 900 Kbit/s for voice traffic. I tried setting a service-policy on the linknet interface on each ASA and set Traffic match to Any traffic and QoS settings for both input and output.
I can see traffic passing the policy when I run the "show service-policy police" command but it never seems to be high enough to be policed which is strange since the ASDM monitoring shows that I'm pushing 3900 kbit/s. I file transfers verifies that policing does'nt work.

I have got a TP link wireless router connected by TP link power line ethernet adapters connected to my sky box, one to Samsung Smart TV, which both work fine the third I have connected to my computer. This shows up as as a local area connection but with no internet access. I have similar problems to other people with internet access dropping out after installing Windows * and had hoped an ethernet connection would be more stable. Any thoughts on why I can't connect to the internet via my powerline adapter.

I am currently in a situation where I want to share internet between a couple buildings at the site I work at. The problem is that it is a forested area and the buildings are about 1/2 mile away from the source of the internet. The only physical connection of the buildings is the phone lines running between them. Is there any way to use the existing phone line to transfer the internet connection to the other buildings and split it between 2 computers. I know that it would probably involve a substantial loss of speed, but I'm ok with that as the internet at the other buildings will not have heavy use.

My ISP is Sky who I use for phone calls and internet, the line to my my house was installed by BT several years ago. I live in a fairly rural area and have never had more than a 1.5mb connection.
Two months ago a neighbor who was repairing his guttering accidentally broke the main phone line coming from the pole directly to our house (the ladder he used was left unattended and it fell over catching on the wire). The line broke in the middle of the length that runs from the pole directly in front of our house to the connecting shackle on the house fascia board, on the first floor.
I connected the broken wire back together, I only have one line in, so all that needed to be soldered were the white and orange wires. The other colored wires I cut flush. The remaining three steel core wires i used as holding wires. Everything was heat shrink sealed, insulation taped up, heat shrink over the whole lot and then more insulation tape put over the whole join, allowing around three or four inches over run at each end of the join. Afterward I did a quiet line test (17070 option 2) and the line was good. My internet speed was as per usual, 1.5mb.
Last Wednesday I was checking my email and web pages kept timed out, i logged on to the router and checked the speed I was connected at. My speed was 560kbps / 56k. After several router resets the speed was still not any higher. I did a quiet line test again and there was a considerable amount of line noise.
As it had rained a few times since my repair to the wire I thought it best to check to see if any water had gotten in. Unfortunately, even with all the insulation water had indeed got in. There was a score mark on the cable and that was the obvious route of entry. Upon opening the repair back up I could see the copper wire inside the orange line had turned black. I had to cut back the damaged line about 10 inches total, to get shiny copper cable and remove the scoring on the outside of the cable. I re-joined the line as I had done before. A quiet line test was good, but my internet speed remains at 560kbps / 56k.
I bought a new ADSL filter, and have tested the router directly in the master test socket without my phone extension, no difference in internet speed at all, and like I said the quiet line test is perfect.
Before I bite the bullet and get BT to come and renew the cable (which I am going to get done, when my neighbor can afford it) is there anything that I could have overlooked, or is it possible that the water has damaged something i.e. the Sky router or other parts of the cable?

About a week ago I changed over 9 HP Procurve switches that were previously stacking in series (yeah, daisy-chain) to a Access-Distribution type scenario with 2 (or 4 on server switches) Gb ports on each switch Trunked together connecting to a central full 48x Gb switch.
During this I updated firmwares on all the switches (most still on their shipped 5-8 year old versions) to the latest stable release (and in the process found out that HP switch firmware is absolutely brutal and untested - See ProCurve 2510G FW 11.16 as an example) .
I saw vast improvements across the network immediately after the change (wow, really? 9 48-port switches effectively sharing a single 1Gb line to the servers and internet was a bit slow? Don't tell my co-workers, they don't think that's possible ) .
The only thing that I didn't see an improvement in was on some Linux and BSD servers, which would top out at 11MB/s doing a SMB (SAMBA) transfer. These are managed systems part of our business system, but we still need to be able to pull local backups for ourselves. So I contacted our vendor. The vendor confirmed that the line speed is showing as 1000T-FDx (same as the switch is showing).
Vendor is now claiming that after these changes were put in place, the speed on their servers (and their servers ONLY) was reduced to a maximum of 5MB/s (~60Mb/s?) doing rsync transfers between themselves. And they are all on the same 2510 (48 port all 10/100/1000), which makes absolutely no sense whatsoever to me. Furthermore this is on the ONLY switch on the entire network that had an updated firmware already installed - that's not even a possibility here.
I put some windows servers on that switch and can get 60MB/s+ all day (SMB transfers). I've also tried from their one server that I can access to doing an rsync or scp to another BSD box, and max out at 15MB/s (with 100% CPU usage on the test box - I'm assuming the decryption is pretty heavy?)There is absolutely no QoS, limiting, or any possibility of throttling the links the servers are on the switch. There are no excessive broadcasts saturating it, and the ports and cables test fine.

I have been trying in vain to setup my home network so that I can perform wake on lan (WOL) over the internet. I have been able to do WOL with a magic packet utility within my local network - so I know that the PC NICS are configured correctly - but this does not work when I try it from my office for example, over the internet.
I have a virtual server set up forwarding ports 9 and 7, UDP to 192.168.1.101 initially, but found some threads about using the broadcast address so changed this, but still no luck. I had to downgrade to 1.20 from 1.21 as I found several threads here about firmware versions not allowing broadcasts.
My setup is as follows:
Router: 192.168.1.1
PC1 192.168.1.101 (static assigned by MAC address in the router)
PC2 192.168.1.102 (static assigned by MAC address in the router)
Broadcast address was 192.168.1.255
