Configuration Of Video Conference On Cisco 1751 Using Internet Leased Line
Feb 20, 2012
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.

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.

Site A Cisco 2911 -- 2 T1 WIC. One going to Site B 1841 another going to Site C 1841.I am looking for a way to setup a Polycom QOS, judging by several forum posts about this, would it be better to create an access list with the Polycom IPs to limit the bandwidth to 512Kbps? Or if not, a link for Polycom QOS configs? What is happening is when noone else is using the connection except for the video conference, after about an hour with the T1 not being 100 % utilized, the 2911 GE0/0 interface will start developing input queue errors. What I usually have to do is reboot the router at night and that alleviates the problem since regular data traffic will not cause this problem.
Current configuration : 3529 bytes
version 15.0

I have connected CeeLab C300 video confernce system to our lan connectet to linksys wag200g. I have forwarded all the ports listed in manual to work without public ip. The problem is that system connect with our branch in other city, sound is great but i have no video on our tv. The other side has an audio and video but using public ip. Is a wag200g compliant to work with videoconferencing system? Support of the Ceelab ask me that Linksys is capable to NAT the H323 codec for audio & video/

There are two Polycom devices behind ASA (Terminal HDX7000 and MCU RMX1000), ASA is connected to Cisco 1900 router which is connected to ISP.
Polycom devices are NATed (unique global address per device) on router and h323 inspection is done on ASA. The issue is that when trying to connect from outside to conference on MCU I don't receive any video (but MCU shows me like a connected participant). The same is true when MCU try to call outside terminals, they are shown as connected participants, but there is just a black screen. On ASA all ports are opened (both in and out) and there are no ACLs on router. And what means NAT configuration on Polycom devices, why it is needed when NATing is done on router (such configuration option I've seen also on Tandberg and another vendor's devices)?

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.

my client wants to make videoconference call thorugh Microsoft Office Communicator, this should be operating between host from one site to another one, but we already configured some rules in the firewalls, and making some test I see that the videoconference use dynamic ports (1024 to 65535) and if we let to operate the videoconference we should remove all the rules in the firewall and that's not the point.

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 do not have a cross over cable and have to use xmodem. I set the baud rate to 115200 and I can see everything fine. Using Tera Term when you send the file via xmodem it freezes and closes on packet #3 or about 384 bits. When simply clicking the send file button you get the error-
*** Reserved LVL 7 Interrupt ***
PC = 0xfff0bc98, Vector = 0x500, SP = 0x80004c4c
Not sure what to do from here. I have tried everything.Error you get when you boot the router:

about three months ago I set our 1751 router as the NTP server of our domain for both our AVVID phone system and our Microsoft Active Directory domain. Been working excellent up until last night. Our company's building had a power cycle and the router got rebooted. Not a huge issue, since it's actually been rebooted a couple of times since becoming the ntp server.
After it's reboot, the time somehow jumped ahead an hour according to all the devices that sync with it. Phone calls stopped working and Active Directory pretty much became useless.
I finally had to break all the devices off of syncing with the router and set them back to the way they were (phone servers sync with each other, active directory doesn't sync with anything externally). It took a few hours to get everything stable again, and I'm still working on parts this morning.
Here's what I've had setup now for three months, we're in Central Standard Time:
ntp clock-period 17179971
ntp master
ntp server 69.26.112.120
and I set the "clock timezone CDT -6" It's been like that for three months and everything was fine till last night when it went out of wack.

I have a Cisco 1751 that I wanted to use to create another network behind my Actiontec m1424wr Verizon router. My plan was to connect a linksys wrt54gs to the Cisco router for device connectivity. And I wanted everyone else in the house to still be able to use the Verizon router as expected. I know this is probably not the best way to create an internal network. But I am studying for the CCNA & CEH and just wanted to use the Outdated Cisco IOS on the 1751.

Connected via wireless. All ok and says have Internet connection, but cannot access any video content' I.e. iplayer, etc. when check via refresh internet content (as Sony recommend) says "configuration failed while connecting. The system has encountered an error. If problem persists contact Sony (5006)". Sony say wireless strength insufficient, but when tried wired set up be relocating NETGEAR router gives same error message. Have NETGEAR wireless extender good signal with full connectivity via laptop, iPad and iPhone. Also when try server display settings says servers cannot be recognised. When go to options and select update list repeats "servers cannot be recognised. Have checked all IP etc and same as on laptop:

I am current trying to configure the network settings on a standalone DVR.I have been doing trial and error all day long to get a 'SUCCESS' on a 'check' while entering the DDNS SVC information.After figuring out that the IP Configuration & Allocation of the Network in the router was messed up, I finally got the DDNS SVC to give me a 'SUCCESS' reading. Thus, enabling me to remotely access the digital video recorder via a Internet Browser.Here's the catch ;I am only able to access the DVR from the PC that has the configuration of the network. (example 10.0.0.1)and the settings on the DVR have been set to :IP : 10.0.0.5ubnet Mask :255.255.255.0Gateway : 10.0.0.1DNS : 10.0.0.1Port of device is set to 20410.So entering http://10.0.0.5:20410 directs me to the webclient that enables me to remotely access the device

I can't seem to skype or video chat of any sort (ie: aim video chat, facebook video chat, etc.) on my computer. Whenever I start skype or try to start a video chat on aim/facebook, it fails and my internet disconnects for everyone. I don't know what could be wrong. Using the same wireless internet, my friends are able to video chat on their macbooks. It seems like my computer is the only one that can't video chat. Video chatting works when I use a sprint internet card. I have a sony vaio laptop running on windows 7. Our router in our apartment at school is a D-link wireless N? In addition to this problem, my internet loves to disconnect randomly too...this problem also persists at home with my Cisco Linksys router (model WRT160N V3) and Speedstream 5100 modem.
