Clients cannot ping the default gateway when connected to SSID

Here is my environment,
My controller is vWLC installed in ESXi which has to vNet Cards configured with all vlans(4095), then it is connected to a 3560 switch with trunk. The configuration of the switch interface is as belows:
LS3560CG#sh run int fa0/1
Building configuration...
Current configuration : 138 bytes
interface FastEthernet0/1
description To_WLC
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
end
The IP of management interface of WLC is 10.10.10.90, VLAN is 10, DHCP primary is 10.10.10.1 which is in the 3560, the DHCP pool is configured as blows:
LS3560CG#sh run int fa0/1
Building configuration...
Current configuration : 138 bytes
interface FastEthernet0/1
description To_WLC
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
end
The SSID is BYOD and I can connect the SSID and get the IP address such as 10.10.10.118/24, but for now, i cannot ping 10.10.10.1, but i can ping 10.10.10.90:
Can anyone help me with this? Thanks

Hi Scott
Correct! I have resolved this a few minutes earlier. I have assigned the vSwitch to Promiscuous Mode but forgot to switch it to "Accept", the default value is "Reject"
Thanks so much!

Default Gateway when connected to VPN

Thanks for reading!
This is probably a dump question so bear with me...
I have set up a VPN connection with a Cisco ASA 5505 fronting internet, with the customers environment behind it (on the same subnet), When connected ot the VPN I can reach the inside Router fronting me and one switch behind the Router (every switch is connected to the router), but nothing else.
My beet is that the Router is messing with my connection, but,, nevermind that!, the setup ain't complete anyway... my question is more related to the Gateway I'm missing when I'm, from the outside, is connected to the VPN on the ASA, could this mess it up? Shouldn't I have a Standard-Gateway in the ipconfig settings in windows?
This is who it looks like now:

The internal network is :

I didn't realise I had that crypto settings on, thanks my bad!!!
But... the 172.16.12.0 network is directly connected, the Router (that to be honest is a firewall) / switches is all on the same subnet (172.16.12.X/24), so sorry I didn't explain thoroughly, was more wondering about the GW and didn't want to overcomplicate things..
The Firewall/Router dosen't do any routing, so it should work right (I you count out the firewalling in the firewall and so forth, there shouldn't be any problems accomplishing this with the ASA)? The Firewall is more a DHCP for the clients/Firwall for the clients.. this will change in the future.. it will be removed,
the vpn network is staticly routed back to my ASA in that firewall...
I don't like this solution.. but this is who it looks.. for now..
(VPN network is 10.10.10.X/24)
But... shouldn't I see a default gateway under ipconfig when I'm connected to the VPN from internet, on the vpn client that's vpned in, is this correct?
THANKS for all the help!

I have a Airport Express I use primarily for AirPlay with my iPhone 4 (iOS6.1.3). Is there a way to set AirPlay as the default audio when connected to wifi?

At the moment, when I re-connect to wifi (come home), I must select AirPlay as the desired audio.
I know this is managble, but it would work a lot more easily if it was possible to select a default for AirPlay, or iPhone.

I would suggest that you perform a "soft" reset on the AirPort Extreme Base Station (AEBS) that you just got from eBay. This type of reset will temporarily (5 minutes) disable both the base station and wireless security passwords so that you can access it with the AIrPort Utility to make the necessary changes.

Why should client PCs always know the default gateway?

Considering that my home computer has only one connection and it is to my ISP,
why does it need the default gateway to be configured (being DHCP client)?
Where else my connection can be deviated from this unique connection cable?
Is it possible to configure a router to which my PC is connected and, then,
the client PCs would not need to be configured with default gateway?
Or client PCs always have to know default gateway?
Why?

How IP Packets are Routed on a Local Area Network
http://www.anitkb.com/2010/06/how-ip-packets-are-routed-on-local-area.html
Thanks, this helps but still confuses.
The article tells:
" Now that WK1 has WK2's MAC, it can send the packet directly to WK2"
A)
I do not understand what does it mean if computer has one outgoing network cable to switch.
It is switch who has different connections and, thereafter, can commutate different communication circuits.
So, I can only understand that WK1 somehow tells to switch to connect him directly to WK2 but not to router.
How?
B)
Were WK1 and WK2 connected directly to a hub, instead of switcher, would they be able to communicate directly?
(The definition of a hub is that it takes a signal and broadcast it through all connections)
C)
Also, reading about switch-router-hub, I cannot understand which role is played by a client computer in communication
(of a hub, of a switcher?)?  Neither of them? What?
A. I believe a fundamental understanding of what a switch and the differences and the similarities between a hubs, bridges and switches, as well as the OSI model, may be helpful at this time.
First, the OSI model is an industry standard defining how hosts communicate with each other. There are 7 layers. THe bottom layer has no intelligence and is the physical connection. As you go up the ladder, the intelligence increases.
7 Application (Application Gateways, Proxies, etc, operate at this level)
6 Presentation
5 Session
4 Transport (TCP, UDP, SPX live here and operate at this layer, NAT overlaps 3 & 4)
3 Network (IP & IPX live here. NetBEUI and DLC overlap 3 & 4. Routers operate at this layer)
2 Datalink (MAC addresses live here. Bridges and Switches operate at this level)
1 Physical (Hubs operate at this level)
Hubs, Bridges and switches allow ethernet hosts to communicate with each other, no matter what protocol is being used, whether TCP/IP, IPX/SPX, NetBEUI, DLC, etc.  They transmit packets on the network.
A hub is a Layer 1 device. It is a dumb device blatantly allowing all hosts to communicate to each other with no discerning source or destination addresses, whether MAC, IP, IPX or any other factor, in the packets.
A bridge is a Layer 2 device. It bascially has two interfaces connecting two network segments together. If a host on one side of the bridge, we'll call that SegmentA, is trying to communicate to another host on the same SegmentA, the
bridge will not allow the traffic to go to the other segment on its other interface, SegmentB. This helps reduce unnecessary traffic and reducing collisions, which slow down the network. If the host on SegmentA is communicating with a host on SegmentB, the
bridge allows the traffic. This is because a bridge has enough intelligence to read the Link layer, which has the MAC address (the physical address) of the interface or network card. It can read the source and destination MAC and determines whether to allow
that traffic across or not depending on where the source MAC is and where the destination MAC is.
Switches are basically multi-port bridges. When a switch intializes, it reads the MAC addresses of all connected devices and creates a "destination table." Notice I didn't say "routing table" since that is associated with IP addresses.
Therefore, if a host on port# 14 on a switch needs to communicate with a host on # 33 on the switch, the switch reads the source and destination MAC address in the Datalink Layer (Layer 2) and knows the destination is on port# 33 based on the destination
lookup table it created of all connected devices. It will then only send this traffic between the two ports. This essentially reduces unnecessary traffic on other ports increasing efficiency.
There are also Layer 3 Switches. They are combination switches and routers that can be managed where you can configure each port to either be switched or routed.
So to answer your questions:
A)
I do not understand what does it mean if computer has one outgoing network cable to switch.
It is switch who has different connections and, thereafter, can commutate different communication circuits.
So, I can only understand that WK1 somehow tells to switch to connect him
directly to WK2 but not to router.
How?
As explained, the switch simply discerns traffic by MAC address. The client side TCP/IP subsystem using the ANDING process, as I've explained earlier, and JM's blog explains, determines where the computer is sending the packets. A computer does not "Tell"
the switch or hub anything. It simply dumps the packet on the wire and the switch reacts to what it finds in the Datalink layer, and if a hub, it simply sends the traffic on all ports.
B)
Were WK1 and WK2 connected directly to a hub, instead of switcher, would they be able to communicate directly?
(The definition of a hub is that it takes a signal and broadcast it through all connections)
It's not called a 'switcher.' It's called a 'switch.' As explained, a hub blatantly broadcasts traffic on all ports. It is up to the sending host and receiving host to read all packets and figure out what belongs to it or not. If a destination address doesn't
apply to a computer that hears the data, it simply ignores it.
C)
Also, reading about switch-router-hub, I cannot understand which role is played by a client computer in communication
(of a hub, of a switcher?)?  Neither of them? What?
The computer is simply plugged into these devices. The devices have their job to do, and the computer has its own.
I hope that explains this part of your networking questioning.

Either there is no default mail client of the current mail client cannot fulfill the messaging request-----error Outlook 2010

I've tried EVERYTHING suggested in this link (http://blog.timolthof.com/outlook-no-default-mail-client-error/) and everything google and bing and still this message keeps popping up. Now when I do a windows search for email, I'm not able to view
the email due to this message.
For the record, I am running W7 Ultimate x64 and connected via Excange Server. I do have another system that is running Office 2010 with none of these problems so I don't know if it's related to Exchange though the searches I've done don't allude
to that.
What's up?

Hi,
I understand that when you tried to open Outlook 2010 beta on the Windows 7 64-bit computer, you encountered the following error:
"Either there is not default mail client of the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and
set it as the default mail client."
You have checked the settings under the registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Clients\Mail\Microsoft Outlook
I understand the inconvenience you have encountered and appreciate the time and effort you spent on this issue. Please be assured that I
will try my best to help you.
Now let’s troubleshoot the issue by the suggestions below. Please check the results after each suggestion until the problem is resolved.
Suggestion 1: manually set Outlook 2010 as the default e-mail client on Windows 7:
===================
1.
Click Start.
2.
Type "default programs" in the
Search box.
3.
Click Default Programs under
Programs in the search results.
4.
Now click Set your default programs.
5.
Highlight Microsoft Outlook on the left.
6.
Click Set this program as default.
7.
Click OK.
Suggestion 2: Start the Outlook program in safe mode
==============
1.
Click Start, point to All Programs, and then point to
Microsoft Office.
2.
Press and hold the CTRL key, and then click the Outlook program you want to start.
If the problem does not occur in the safe mode, this issue might be related to some third-party add-ins in the Outlook program, we can try
to disable them. Normally, you could do the following to disable the conflict add-ins in your Outlook program:
Disable add-ins
Click
File menu, click Options >
Add-in, click Go button in the Manage:
Com-in Add.
Check if there are any add-ins,
clear the checkbox to disable them.
Close the Office program and
restart it.
Add one check back each time to the list of Add-In,
restart the Office program, and repeat the above procedure. Once the issue reappears again, we can determine which add-in causes this problem and then disable it.
Suggestion 3: Test the issue with a new Windows user account
==============
We can follow the steps in the articles to create a new user account to test the issue. If the problem does not occur in the new user account, some settings
in the old account are corrupted. We can copy the main user files from the old account to the new account, delete the old account, and then continue using the new account.
For the detailed steps on how to create a new user account and copy data from the old account to the new account, you can refer to the following articles:
For Windows Vista/Windows 7:
http://windows.microsoft.com/en-us/windows-vista/Create-a-user-account
http://windows.microsoft.com/en-us/windows-vista/Fix-a-corrupted-user-profile
Please take your time to try the suggestions and let me know the results at your earliest convenience. . If anything is unclear or if there
is anything I can do for you, please feel free to let me know.

Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run ...

Lync 2013 generates repeated messages stating “Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.”. Events that
seem to generate messages is disconnecting and re-connecting to a network but it also happens randomly and the messages will stack up during a working day. Everything seem to work OK but it is an annoyance. The computer is upgraded (uninstalled first)
from Office 2013 ProPlus to Office 365 ProPlus. Outlook (Desktop) is default mail client. 64-bit Windows 8.1 Enterprise, 64-bit Office (both before upgrade and after).
(Links removed to remediations I've tried)
Made no difference what so ever and the messages continue. What's next?
I posted the above to the Office 2013 forum (unfortunately I'm not allowed yet to post a link to that posting) but due to the fact that the computer affected by this is a networked domain computer I've been redirected to this group instead. I
was asked some additional questions ing the other forum regarding the problem:
Are you able to send mails from other applications like Word or Excel?
NO
Is the PC connected to any Domain/Server? YES
Is this an issue with one PC only. NO - affects all computers that once had Office 2013 Pro Plus installed and now has Office 365 Pro Plus (Originally I posted this question in the Office 365 community but was directed to first the Office
2013 forum and now this forum)
Right click on any file and Click on Send to-> Mail Recipient and check if you are able to send mails using Outlook.
NO
Also check if the Lync add-in is enabled in Outlook.
Start Outlook
Click the File tab.
Go to Options.
Click Add-ins.
Check if the Lync add-in is enabled. YES
My last posting in the other forum contained the following additional information regarding our problem:
As far as we can see installing 32-bit Office 365 Pro Plus using click to run makes no difference.
We do not send any mails from Lync, Lync is however the process that generates the message most frequently (as Lync seem to react upon network events).
Other processes that have Outlook plugins may also be the parent of the message popup (third party applications).
Yes the Lync add-in is enabled. Lync functionality in/from Outlook seem unaffected.
It is not possible to send emails from other applications (explorer, word, excel etc.) ie. right clicking and send to generates the messages and
a follow up error message concerning lack of MAPI enabled e-mail.

How get the RVS4000's DHCP server to assign another IP address other than its own as the default gateway to its DHCP clients?

Hi,
I have a RVS4000 router with DHCP enabled and in router mode.
The LAN is 192.168.2.x. The RVS4000 static IP address is 192.168.2.8
The router is not the RVS4000 and is at 192.168.2.1
The RVS4000 dhcp is assigning it's clients a default gateway of 192.168.2.8 instead of what I want 192.168.2.1.
How can I get the RVS4000's DHCP server to assign another IP address other than its own as the default gateway to its DHCP clients?
Thanks

Hi Gail, you cannot do this. The router, as the DHCP server will only assign a default gateway of what IP interface the DHCP server runs on. If you have the default IP, the gateway is 192.168.1.1. If you create a second vlan, by default it would be 192.168.2.1.
There are not configuration options for the built-in DHCP server. If you'd like to expand this functionality, you would need an external dhcp server.

How to setup default gateway in a DHCP client. The default gateway will be the Ip address of the server that has RRAS installed, hence routing cabalities.

Hi Bill,
Thank you for replying back...Yes, I was actually asking how do you set the default gateway address on the DHCP server?,
I believe I got the answer below:
To configure the DHCP default gateway option Click Start, point to Administrative Tools and then click DHCP. In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Scope Options Click Configure Options, check 003
Router, type the applicable Server name and IP address, and then click OK.
Thank you

WRT350N : how to specify the default gateway?

Hello,
I would like to use my wrt350n as a dhcp server, but want to specify another router as the default gateway.
I have my wrt350n (192.168.1.254) and another modem/router (192.168.1.1). When a client connects to the wrt350n, it automatically receives as default gateway the adress of the wrt350 (192.3168.1.1). I would like to change that to reference the other adress 192.168.1.1.
Thanks for your comments
Raph
Solved!
Go to Solution.

Hello,
Thanks for your answer.
I try to give you more information.
The modem router (bbox2 : 192.168.1.1) is connected to an ethernet port on the WRT350 (192.168.1.254). I would like to desactivate the DHCP server on the bbox2 (because limited to 802.11g), and activate it on the wrt350, to have a wireless network in 802.11n. The problem when I do that, is at the dhcp server, the default gateway returns is always the ip adress of the wrt350 (so no internet access). Nevertheless, I have to specify the ip of the bbox (192.168.1.1) for the internet traffic. I don't find a way to change the value of the default gateway returns by the wrt350. I can set different values for DNS, but not for the gateway.
Actually, I turn on the dhcp server on the bbox and turnoff it on the wrt350, but my wireless spped is limited to 54Mbits (802.11g), and this not annoying for surfing purpose, but annoying when streaming video from my san connected to the wrt350n.
I don't know if it's clear now?
Thanks for your feedback
