With my current setup on the 5508 controller, I don't have the ability to see any name resolution for wireless clients. I'm wondering if there is some way that I can enable this.
The reason I think this should be pretty easy is because if I enable the access point feature of a smart phone (Android or iPhone), when a client connects, it shows the client name on the smartphone. What's different about how a smartphone sees the wireless client and how WLC/WCS sees it?
How to feel about having network devices resolve names? Do you typically do it? No? Why or why not?I feel like I haven't seen it set up a lot, but it could certainly be good for specifying logging hosts and things like that.
View 7 Replies View RelatedI'm having with my VPN Server on my Cisco 2621xm.
I started by creating a VPN - everything worked great. I assigned the DNS Servers, Domain name, WINS Server so when I connect I'm able to resolve local hostnames on the network with no problem, however I couldn't connect to the internet. I then set up a split tunnel access list. Since I've set that up, I'm now able to ping internet based addresses (www.google.ca), but no longer able to resolve internal host names. I can ping the ip addresses, just name resolution no longer works.

View 3 Replies View RelatedMy RV220w has a problem with DNS. I have configured the device for my network, but it seems as though DNS is not working correctly. For a background, I have a primarily Windows environment in my network, W7 PCs. I use homegroup to share files/printers amongst them. I like that I can type "\<server-name> in the Windows search box, and up comes the other computer's files. This functionality is still there with the RV220w, so that's not my issue. My problem arises when attempting to type "<server-name>" into the Remote Desktop Connection dialog box. I can no longer RDP to my other computers by name. Attempting by IP does get me there.

I am using code enterprise 15.1-2.SG and here are the relevant config snippets:

I read online there are some commands in a different code that support specifying the VRF along with the name servers, but I don't have those options. All I can do is set the source-interface on the domain-lookup command.
I have been trying to get my 851W to work with DDNS for a long while now. In fact I walked away from the problem in frustration and loaded DD Client on a Linux box until I had time to re-visit this. The folks at Zone Edit were not able to offer much with CLI problems.
When I debug DDHS updates I get to a point where the the router tries to resolve the DDNS update address and fails.So I have a number of questions:
a) Is this error the result of lack of DNS server names written to the config?
b) My WAN interface is a DHCP client to my modem. If the DDNS updater does need to resolve a name, shouldn't the DNS server info be provided by the DHCP process for the WAN interface? How do I ensure that name servers are automatically assigned for the DDNS updater to use?

I like the ASA 5505 for SMB and Home Offices very much, but I'm missing sadly a DNS Server or at least the ability of the DHCP Server to use static addresses for certain MAC's. In SOHO's the ASA is the only thing always powerded on and often even a Server where a DNS Server could be installed is missing.So is there a chance to see such a feature (DNS Server and/or static DHCP) in the next SW Release? how name resolution in a small LAN can be done without a local DNS Server?

View 3 Replies View RelatedI'm running a Windows Server 2008 R2 connected via cable to my RV220. The server is hosting several websites running in separate virtual machines. These websites are accessible through a reverse proxy set up on the 2008 R2. In addition the 2008 R2 provides access to storage over Windows file sharing (client backup, file sharing ...). Most of the clients are connected via wireless.My problem is that after some time (~24h) I lose the connection to the services provided by the 2008 R2 server as a result of (host) name resolution has stopped working. This only happens for wireless clients. Wired clients are not affected.To give more details: Network clients connected via wireless can't see clients connected via Ethernet and the network shares are not accessible anymore (even by putting in manually "\hostnameshare", but "\[IP address]share" still works). Being connected via Ethernet the communication between client and server works flawlessly - the server appears immediately on the network device list. The other way around is also not possible: the server can’t see clients connected via wireless. The reverse proxy is still accessible through wireless connection by putting in the IP address, e.g. "http://192.168.1.123/homepage" but "http://hostname/homepage" won't work.A restart of the router will fix things but only for the next couple of hours.

I just purchased an E2500. I have a small home network dominated by Mac and Linux boxes, with an occassional Windows machine. On my previous router I had been running OpenWRT.
One of the nice features of DNSMASQ is that it will do local name resolution from the /etc/hosts file on the router. Is there anyway to turn on similar features in the E2500? I have a NAS box and a networked printer that require local name resolution. I had hoped that I could just create a DHCP reservation for them, and that the router would resolve their names for other hosts on the network. This does not appear to work.
Should I just be boxing this thing up and returning it in favor of a unit I can flash better firmware on to?

View 7 Replies View RelatedI have an 1841 running Advanced Security IOS (12.4(25) I think, have to check when I get home) that I'm using to learn about CBAC and IOS' firewall functionality. Its external interface is connected to my Windstream DSL modem in bridge mode, and the router is doing the PPPoE authentication. It's also doing NAT for my internal network, and is acting as a firewall using CBAC inspect statements and ACLs.
Everything is working at at least a baseline level: the DSL authenticates and connects, and machines on the inside can browse the web. The problem is that browsing to some sites is slow or times out. Not all sites, just some. Latency seems to be okay when doing pings. The problem seems to happen with https connections, but again, not all of them. Gmail works fine (I have it set to always use https), while my bank and credit card sites either time out or take minutes to load.
I have an "inspect https" line in my config, and have allowed https through my outbound ACL.
I'm looking for next steps for troubleshooting this. I've check CPU utilization and it's very low; not sure what else it could be. I only have a few inspect statements, for the common stuff: tcp, udp, icmp, pop3, imap, dns, tftp, ftp, and ntp.

I've just recently upgraded a Cisco 877 to 887W router.
I basically copied most of the config across to the router with no problem.
ppp chap hostname and password all ok. ATM and Dialer1 interface comes up.
The problem I'm having is when I open Internet Explorer up, default homepage is Google. Google loads up fine, type a search is fine but when you click on the link or type URL, for example BBC News or Sky Sports, it takes a long time to load or times out (Page cannot be displayed)
DNS servers configured on Cisco router are: 8.8.8.8 and Virgin's DNS servers.
NSLOOKUP in cmd prompt it returns IP add no problem. however in web browser it fails except for Google.
However, with the same config on a 877 everything works perfectly...

Material in question:
Router Model: RV082
Firmware: 2.0.0.19-tm
Only primary WAN port used
Description of problem:I've had a 50mbps internet line with a 2mbps upload for a couple of weeks. I thought my ISP was having trouble because I was only getting 30mbps down and 700kbps upload with noticeable packet loss, however after connecting a laptop directly to the modem after office hours, I realized that I can reach 53mbps down and almost 2.5mbps up. But when I connect directly into the router I only reached the much slower speeds mentioned above previously. (40-60% slowdown)All transfers over LAN reach their full 100mbps transfer speed. So it seems to just be a problems with the WAN.My next move is to back up the router, flash it and then try it with basic default configurations to see if a setting is causing the slowdown.On the other hand, it just occurred to me that perhaps the router was not designed for such a fast line. Does the RV082 can handle a 50mbps internet connection? How to successfully deployed such a fast internet line with this router?
We have a network between two locations. WAN is 100 Mbps MPLS provided by service provider. There is a FWSM module on core switches. Problem we are facing is FTP file transfer between two servers across WAN link never crosses 20 Mbps. Link is 100 Mbps. However if we do parallel file tranfers each transfer is 20 Mbps . But we dont get transfer rate above 20 Mbps in a single FTP session. Is there any bottle neck where traffic is getting restricted.Traffic between two mservers passes through 100Mbps MPLS WAn link, 6500 core switch and FWSM module in switch.

View 4 Replies View RelatedI have just got a cisco 1720 router and set it up for my internet connection.I have a cable modem and when running on any previous cheap firewall I could pull about 15 meg download.Now I can only pull about 9.3 meg download.But saying that does not really explain it well as there is a serious lag when I go to a page even like google. When I go to my android phone and download updates, it downloads them one at a time - before putting in this router the updates would come in all at once - not one at a time.
The cisco has an addin 4 port switch which connects to my network.I am connecting the cable modem to the built in fast ethernet 0 interface.
I am not that good with Cisco so I may be doing something completely wrong but don't know where to look.Here is the interface commands I have used on the external FastEthernet0 interface, [code]
Oh by the way I have set the duplex and speed settings to auto but seems to make no difference.
I am not a network person, but I am not sure our Network Team is qualified either. For a long time we have been using a dying Cisco 2950 100/MB switch for imaging our computers using GhostCast. Multicasting on the 2950 was never an issue other than it was flooding the switch and making all the other ports unusable. But at least the multicast portion was imaging with decent times. We had two Intel Pro NICs teamed to get 200 MB/s and a typical multicast session was about 6.5 minutes. When using only 1 NIC, it takes about 8.5. Running two concurrent unicast or multicast sessions, well that is a different story. It then triples or quadruples the time.
Now we have a 3560G setup. A single session takes a little over 3 minutes. If we multicast off of this switch, the time is about 12.5 minutes. That is 4 minutes longer than the 2950! If I run 3 concurrent unicast sessions, it takes all of them between 3.5 to 4 minutes. So obviously there is an issue with multicasting.
The switch is in a lab separate from the production network. The server with our ghost images is plugged directly into the switch and so are the computers we are imaging. From what I was told from the Network Team is that IGMP snooping is on, but multicasting is off. He said that multicasting does not need to be turned on since all traffic is going through the local switch. Probably true since our old switch didn't have multicast turned on either, but it still imaged using multicast faster.
Below are some screen shots of the imaging. The first one is the 2950 using multicast to 3 laptops. The second one is the 3560 using multicast to 3 laptops. Finally is the 3560 using 3 unicast sessions to the same 3 laptops.
I recently inherited a small network. There is an existing 1.5mbps Internet connection (fa0/0) (includes MPLS as well/same provider). We added a new ISP that allows for 50mb down/5mb up. I added the new ISP to fa0/1 and modified the NAT overload statements accordingly. I alo changed the default route to ONLY use the new, faster ISP connection. Using speedguide.net, I am only able to get 6 to 10mb down, most of the time. if I plug a laptop into the cable modem then I get 37 to 50mb down. Why the 2811 is so slow?
I have attached the config and various show outputs (nat, sh ver, memory, etc.). the file called "latest logs" contains a "sh ip traffic, sh int switching and a sh proc cpu sorted". [code]
This is a multi site network. Site A has a Cisco 3825 router and connects to 3 other sites over ISP A and 2 other sites over ISP B. Both ISP A & B provide a layer 2 full mesh network. ISP A provides a 100mb pipe while ISP B provides a 20mb pipe.
File transfers (Windows - CIFS) over ISP A's fiber are fast enough and throughput is good. However, file transfers (Windows - CIFS) over ISP B's fiber are slow, even though latency is good. On the 100MB ISP A pipe, file transfer speeds up to 6 M Bps are achieved. On the ISP B 20MB pipe, speeds up to 300KBps are seen for file transfers.
ISP A connects to an on board gig port on the 3825. ISP B connects to a fast ethernet port on an HWIC-2FE card on the same 3825. Both ports then connect to ISP Switches and then full meshed to remote site Cisco routers. What could be the issue? Why am I facing these issues only with ISP B even though the configs for ISP A and ISP B are the same?
