Cisco WAN :: 2511 Default Gateway Pointing To ADSL Router
Aug 1, 2011
I have a 2511 TS linked into my CCNP lab and configured it with default gateway pointing to my ADSL router. The TS has a staic local IP in my LAN also I have port forwarding set up on my ADSL router to direct all Telnet (not cofigured for ssh yet) sessions to the TS.
The TS is linked to the ADSL router via the transceiver module ( CentreCom AT-210TS) which feeds the ADSL router with ethernet connection.I have tried to access the TS from a remote location but with no joy, fortunately I also have it consoled to my PC so I SSH to the PC and then run my terminal emulator from there. Using SSH to the PC and then minicom to the TS when doe this way (Remote Location>Ubuntu>minicom>TS) I can see the ethernet interface has no MAC address when i do a sh internet eth 0 mac is set to 0000.0000.0000.
I don't want to be connecting via ssh to PC before accessing the TS but instead just want to connect to the TS; for the life of me I still can't explain what's going on.

My network topology is as follows:
Internet <-> Residential Gateway (RG) from ISP (OEM: Pace) [192.168.1.254/255.255.255.0] <-> RV180 [192.168.1.253/255.255.255.0] <-> SG500 switch [192.168.1.250/255.255.255.0] <-> rest of network.
I know this is a cascading LAN-to-LAN arrangement. The cable from the RG to the RV180 is from a LAN port on the RG to a LAN (not WAN) port on the RV180.
I eventually want to segment my network into a few VLANs from the RV180 down. I am aware most people would recommend DHCP on the "primary" router, but the RG is non-VLAN aware, so I figure I need to handle the DHCP off the RV180. At the same time, I have also opted not to do a LAN-to-WAN cascade because I want to retain the ability to configure the RG from the rest of the network and not have to cart a computer over to the RG to do it.
On the RG, I've disabled DHCP, and placed 192.168.1.253 in the DMZ.
On the RV180, I've enabled DHCP and put it in Router mode.
The issue is that I do not have any Internet connectivity. If I allow the computers in the network to receive IP addresses over DHCP, the default gateway that is communicated is 192.168.1.253, which is the RV180. If I configure static IPv4 information on my computers to point to 192.168.1.254, I am able to connect outside, as you would expect.
How can I get the RV180 to pass out DHCP IP addresses, but point to 192.168.1.254 as the default gateway? I thought the solution might be to create a default route (or something). I went to the static routes tab but it wouldn't let me enter 0.0.0.0 as a destination IP to route through 192.168.1.254.
Further down the line, is it possible for both the RG and the RV180 to connect directly to the SG500, along with the other nodes in my network? That way the RV180 only serves to maintain the VLANs and pass out IP addresses via DHCP, instead of having it be the choke through which everything goes through on the way out?

I just purchased a Buffalo WZR-600DHP router and have been having a weird issue. When using the router on the shipped DD-WRT firmware I consistently get "The default gateway is not available" error and I have to reset my wireless adapter on my laptop. This issue doesn't occur on my hardwired desktop or interestingly enough when the Buffalo router was switched to the "user-friendly" firmware the issue didn't occur either. Both times the router was on the DD-WRT firmware I've had the default gateway issue.

Does ip default-gateway have any effect on a L3 device such as a 2811 router? I always thought that on a L3 device the default route would supersede any such command assuming it is accepted.
We have a client device that cannot be reached for managment directly and wanted to add that statment only if it might work.

hrome threw me a DNS lookup failed. I go into my network settings and I noticed that I had limited connectivity. It would switch between no network access and no internet access every few seconds. After a bit of fiddling around, I got it to connect through assigning myself a static IP. This isn't exactly convenient because I use this computer on multiple networks. When I try to have it on automatic IP, I get no IP address or default gateway when I do an ipconfig /all. It would appear that my router quit assigning my laptop an IP for no reason whatsoever. DHCP is enabled on the router, and all other devices work fine. What could possibly be the problem here? I'm 99% sure it's not an IP conflict either. It's not being MAC filtered because I'm on the thing right now posting this through a static IP. It's not my A/V because it's worked great in the past. Perhaps I should also mention it occasionally says "unidentified network" instead of the SSID

I have a central office and two branch offices, these offices are connected by a private routing service that has no connection to the Internet, the telecommunications operator in each office installs a router with a LAN and a WAN IP and configuration of these devices cannot be changed except the LAN IP. Only the central office network that is 192.168.0.0 have a router that has internet access. Remote offices have no access to the internet, what is needed is that remote offices can access the internet using ADSL router 192.168.0.254 at the central office. There are a small devices in each remote office that must connect to the internet and do not support any configuration except IP, mask and gateway, for example you cannot add a static route. Currently the pc's at remote offices has IP communication with the server from the central office using a static route. put some VPN routers between each LAN and the operator's routers (where RT yellow star appears in the diagram) and put the hosts of the two branch offices same IP range that the central office network? I had thought to use RSV400 routers?

I have a WRT54GX2 router and my laptop is connected wirelessly to the router. It worked fine before but now, the connection is only local, it's not connected to the internet.On the router, it says: Default Gateway: 0.0.0.0.I think that it should say 192.168.1.1 instead.I tried dhcp release and renew but it didn't work.The firmware version is 1.01.22.

I am currently using an E900 wireless router. The router is on the second story so I have to use a wireless router booster to enhance the signal strength. I have been using the booster for well over a month with no issues whatsoever; however, tonight I attempt to get onto World of Warcraft and I keep getting disconnected every 5 minutes. After I run the diagnostic it fixes the problem and says that the "default gateway not available". I tried restarting the router, restarting the booster, unplugging the wireless adapter, checked the firewall, and also restarted my computer.

I would like to know what ip addresses I should see in this table. Shouldn't my default gateway IP have the same mac address as my computer or router? There are 2 different ip address/mac addresses from different a ISP than mine. I have a cisco DPC3825..I suspect a someone is spoofing my DNS.

How can I change default gateway and DNS's for L2TP type of connection? I've tried to specify them in static IP address first and then switched to L2TP as adviced in one forum, but it didn't work. I don't understand why such settings as Gateway and DNS servers cann't be specified as for PPTP connection. Firmware is 2.0.37.

We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATAWe are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites.
Testing
Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for dataThe problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.We are using IP routing, should we be using route-maps?

So network was running fine for about a year or so. Network consists of 1 Motorola SB6120 cable modem attached to a D-Link DIR-601 wireless router. All settings were default except for SSID and WPA password. One day I just couldn't access internet anymore. I've narrowed it down to the default gateway that is being given out through DHCP. The default gateway that is being given out is the IP of the modem (192.168.100.1) and not of the Router (192.168.0.1). I can't find any option on Wireless router to be able to force the gateway address when handing out the gateway IP. Theoretically I thought I should be able to put router on same subnet as modem as 192.168.100.2 but that still doesn't work. If I set the IP adresses statically on the PCs and give it the Gateway of the Router everything works fine. I should mention this is for my boss' house and basically I dont want him calling me everytime he has a friend come over and I have to talk em through setting up a Static IP.
And just for an example this is what I get if I use DHCP:
IP Address: 192.168.0.155
Mask: 255.255.255.0
DNS: 192.168.0.1
Default Gateway: 192.168.100.1
And If I want it to work I have to change the default gateway to 192.168.0.1 I've tried updating routers firmware and reset to factory default numerous times. Is it possible for a router DHCP stop working?

I'd like to add a WRT54g2 to my LAN. I'd like it to communicate with my existing LAN router, and not to talk directly to the LAN. Therefore, in Basic Setup, I don't have the top part (Internet Setup) configured. Is that a mistake?But, it seems that when I enable DHCP, it hands out its own IP as gateway, and then doesn't seem to send the traffic on upstream. When I configure clients manually with the real router IP, they work fine.
So, I'd like, I guess, Linksys to forward traffic on a static route to real router. How do I do this? Adding a route to real router yields the error, "maybe default route already exists."

I am using a WRT310N. I have a Cisco ASA5505 as my firewall and don't need the routing capabilities of the WRT310N. So I just plug the LAN port on the WRT310N directly to my LAN switch. I just need the WRT310N to have an IP address for management. So I configure the LAN with an IP address, but there is no way to set the default gateway on the LAN. You can only set the default gateway on the WAN interface, which I don't use, since I am using this in an AP only type of configuration.

I am using a RV016 (192.168.1.2) as a router and DHCP. It automatically assigns its own IP which is 192.168.1.2. I can not set my RV016 to assign a Default Gateway IP of the server. The workstations will connect to internet via this server (192.168.1.1)

We were hit by hurricane Sandy a couple weeks ago and lost power for a week and a half. Now that our cable has been restored I noticed that the wireless internet wasn't working. The wired internet works fine to this computer but no Wi-fi.I think the problem is the routers default gateway. It's supposed to be 192.168.1.1 but right now it's 24.191.112.1 .So far I have tried:
-Powercycling everything
-ipconfig/ flush DNS
-ipconfig/ release and ipconfig/renew
-Checking all the wires are pugged in fine (They are).

I have my E1200 connected to my Netgear FVS318 router (which is a wired router) and the Netgear is connected to the internet.When a wireless client attempts to connect to the internet after automatically receiving an IP from the E1200, they do not have internet access as the default gateway that gets assigned is the IP of the E1200 192.168.2.100, which is not correct. It should be assigned 192.168.2.1, which is the IP of the Netgear router. Thefore, I have to manually set their IP addresses to use 192.168.2.1. How do you configure the E1200 to assign the correct Default Gateway IP to wireless clients who want to use DHCP?

I've been having a weird issue lately with my WRT310Nv2. Sometimes when we, and by we, I mean two different computers (one Mac, one XP PC), try to go to a website, it will point us to an entire diffrently website. For example, earlier today I attempted to go to Twitter and twitter.com appeared as some random Blogger website. I've had issues where Amazon.com kepting point to UPS.com, or Facebook.com pointing to MySpace.com, etc.
I haven't been able to pinpoint a regular pattern, except the fact that it is most likely the wireless network, since the Windows PC (Server 2003) plugged directly into the router has never had this issue.

Periodically, I drop internet everywhere around my college's campus. I'm literally four feet from a router, but it doesn't seem to matter. I'll disconnect, run troubleshooter, and I'll get the error message saying that the default gateway is not available. My college is designed for Macs, but I'm running Windows 7. My Mac colleagues do not experience problems. The computer works at home and at nearly every other wireless network I've brought it in range of. Specifically, either IBM or Dell.

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]

I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?

We have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?

I am having issues playing certain games on my ps3. So I've been searching for solutions and I came across a video that wanted me to go to run/cmd/ipconfig. I have little knowledge of computers but I'm not sure that what my ipconfig is showing is supposed to be there. At first I googled and learned about ipv6 addresses because i found that weird but i think that checks out fine. I then googled about the weird numbers and letters in my default gateway and came up empty. Is there a reason thats there?
