I have a cable modem with my 2600 Router and i have a little speed problem when I'm going out to the web via my F0/0.. according to regular speed test sites my speed is around 20mbps but when i hook up to my modem directly i get a solid 40mbps.. now I've changed my Cat 6 cable from my modem to my router and this are my settings in the router.

I see some drops and lost carriers but not sure what those might mean?
I work for a small pharmacy that uses a Cisco RV120W router to separate hospital VPN traffic from general internet traffic. The VPN traffic is redirected to a dedicated T1 line (Or T-something, I wasn't involved in the actual setup of the VPN) connecting our store directly to the local hospital, and general internet traffic gets redirected to a ZyXel PK5000Z DSL modem (We have Qwest/CenturyLink 7m/768k). The DSL modem is running the latest version of our ISP's custom firmware.
Prior to installing the VPN and RV120W, LAN traffic was handled with a basic D-Link DI-604 wired router. The router itself was configured with an IP of 10.100.100.254 (With all LAN clients assigned DHCP IPs in the 10.100.100.XXX range) and "WAN" IP of 192.168.0.4, and the modem configured with a LAN IP of 192.168.0.1. The router was connected from it's WAN port to one of the LAN ports on the modem.
The modem has it's own built-in router, but the store owner wished to have an "extra layer of protection", so to speak, and had the D-Link router installed to serve that purpose. Prior to connecting the VPN, a second router was admittedly redundant and unnecessary. However, now that we have the hospital VPN, a second router is REQUIRED to properly separate the VPN traffic from other internet traffic, since the router built into the DSL modem doesn't have the capabilities to perform this task (We had already attempted to operate the VPN over DSL...it failed miserably and spectacularly. A dedicated T1 was the only reliable option).Anyway, when installing the RV120W, we duplicated every possible setting from the old router, including configuring it with a LAN IP of 10.100.100.254 and a "WAN" IP of 192.168.0.4 and connecting it in exactly the same fashion as the old router (Modem LAN to Router WAN). Essentially, the RV120W was set up exactly the same as the old D-Link router, just with the added VPN functionality.
The problem is this: ever since installing the RV120W, we are no longer able to access the DSL modem's administration page (http://192.168.0.1). We were able to do this without any trouble whatsoever with the old D-Link router, but the RV120W seems to be blocking it somehow. Any attempt to load the modem administration page just forever sits at "Waiting for 192.168.0.1...". It never times out, it never shows any error messages. It just sits there, forever trying to load the page, showing nothing but "Waiting for 192.168.0.1..." at the bottom of the screen.
Now, we know for a fact that it is NOT a problem with the modem, because if we connect a computer directly to it via ethernet (Completely bypassing the RV120W), the administration page loads perfectly fine. And, admittedly, we could configure the modem in this manner whenever required. HOWEVER, the modem is located in a rather inconvenient location (In the ceiling, sitting on top of a ceiling tile), and having the ability to remotely manage it like we could before would definitely be something we want to be able to do again...especially since there are plans in motion to install new pharmacy equipment that will require us to do a ton of "trial and error" configuration to the modem.The RV120W has been updated with the latest firmware, yet the problem still persists.
I have a Home Virgin media cable connection at home. the only way to get this working with my Cisco gear is by putting the superhub on modem mode.On modem mode, it becomes just a dumb modem assigning and IP via DHCPI can get the switch to get an IP address from the modem with
no switchport
ip address dhcp
then I have created
0.0.0.0 0.0.0.0 fa0/48
to route traffic to the port connected to the mode,The switch gets the assigned Ip address from the modem but it does not route internet traffic.
From the different vlans and subnets on the switch, I can ping the modem.
From the switch I can ping 8.8.8.8
From the machines, i cannot ping 8.8.8.8
On my machines, what should be the gateway? the vlan SVI, the modem's IP address, The fa0/48 ip address? I have tried them all with no success.
I am with Virgin media and have a home lab (2611 routers, 3550 switches, 2950s etc) which i usually just use for testing things on and practicing.
Now I tried to connect it to the internet and got some weird things happening.
I got NAT and DHCP client all setup correctly on the router (or so I think!) along with DNS settings but I still can't get Internet access.
My network is all setup right so that through using OSPF the router is the gateway (0.0.0.0 route) for all devices. Doing a traceroute confirms this.
Yet I never get any further than the router? I see IP nat translations ticking up as I send more requests but never get a webpage or a reply from any of the machines in my network.
HOWEVER... The router itself does get some replies from Google.co.uk and bbc.co.uk but doesn't seem to want to give anything else on the "inside" a response?

I am having an issue with my network that has me perplexed. I have a DPC3010 cable modem (Charter internet). I previously had it connected to a Linksys WRT54GL with DD-WRT installed and that was working OK except that I had to reboot it 2-3 times per week. I replaced it with a Cisco 861 (non-wireless) router and it worked OK for a few hours then it started dropping the internet connection (it goes up and down constantly). If I switch back to the Linksys everything works fine again. I am using the same cables in either case so I know it's not a cabling issue. I upgraded the firmware to c860-universalk9-mz.151-4.M3.bin, but it made no difference. I was starting to suspect a problem with the physical ports on the router, but I decided to try connecting the 861 behind the Linksys and turns out it works fine in that setup.
So to recap...
If I connect the 861 directly to the modem my internet connection bounces up and down
If I connect the Linksys directly to the modem my internet connection is fine
If I connect the Linksys directly to the modem and the 861 to the Linksys everything works fine (my PC is connected to the fe0 port of the 861)
Are the 861 and the modem simply incompatible or is it a configuration issue? I have attached my 861 config to this thread.
I have a TPLink WDR3600 wireless router wired to AT&T's cable modem.
The modem assigned this ip to the router: 192.168.1.60.
The router creates a network with these IPs: 192.168.0.x
Question: I want to be able to RDP into my laptop that's connected to the router (ip: 192.168.0.4). Before I had a router I would just open the firewall on the cable modem and expose the laptop but now it feels like there's two layers i need to go though: the cable modem and then the router.
How do those two work together? Should I put the router in the cable modem's DMZ Zone and then just work on the router?If I want to open just a port do i need to open it both on the cable modem and the router? How does the incoming connection know which device to go to? How does it know to go to 192.168.0.4 instead of 192.168.0.2 for example?
Here's the components:
1 - AT&T 2Wire cable modem. Internet comes in the house through this box. Assigns IPs like this: 192.168.1.xxx
2 - TP-Link WDR3600 gigabit/wireless router. Assigns IPs like this: 192.168.0.xxx
3. WD My Book Network Storage. Wired connection.
4. Desktop PC. Wired connection.
5. Laptop PC. Wireless.
6. 1 ipad, 2 iphones. Wireless.
Current setup:
1. internet cable goes into 2Wire Modem.Wireless on this device is OFF.
2. cable goes from LAN port on modem to WDR3600 router's internet port
3. cables go out from router to Desktop PC and Network Storage
4. all other devices are connected to the 5GHz wireless network created by the router.
I just switched to Roadrunner Lightening via Brighthouse Networks. There is no configuration capability in the Cable modem/ router / wireless - Ubee provided to make the Modem a bridge. You have to call Brighthouse to do that. They indicated that they only do that for supported routers and the EA 4500 is not one of them. I'm ready to call them to say I have one of the supported modems so "do it" and then find out what happens.
Meanwhile I have connected my EA4500 through their router and have a network in a network. I've noticed another more significant problem. The speeds through the EA 4500 drop to 90%. Is there something wrong with the router configuration that would cause this significant drop in speed? I'm afraid if the problem is the EA 4500.
- I have an older router 2600 running 12.1(4) IOS.
- There are a few clients connected to it via the frame relay connection.
- There is an IP that clients access 192.168.1.10 for example
- We need to do a NAT for this IP for one specific client only like "ip nat inside source static 192.168.1.10 1.1.1.1"
- However if I do that, that will effect other clients too
- On the interface for this client I'll be using "ip nat outside"
- Is there a way to accomplish this without effecting other customers?
I've been working with these two Cisco devices in my home off and on for several months now but I just can't take it anymore, I'm about to throw them away and go back to Linksys router.
I have a Cisco 2600 Router with only one Ethernet card in it so I have to trunk from my 3550 Switch to that device. I'd like to have my ISP and all users plug into switch and all trunk back to the router's sub interfaces. Currently, I have started over...again, and am unable to simply get the router and switch to ping each other if I put sub-interfaces on the router. See my configs:

Port F0/24 is in VLAN 1, as are all ports but Port F0/1 which is my desktop PC. I mocked it up in Packet Tracer and it works just fine. This is just a simple setup and I'm making sure I can ping between switch and router before I move to each next step.
I am trying to configure SDM 2.5 on a cisco 2600.I have access via telnet to the router and was able to change the enable password - which i think is level 15 (right?) and setup (and bring up) the ip on the ethernet interface. I can ping - and get response from - the router Trying to install SDM on the router i need to provide the default username i tried both admin/administrator but SDM can't communicate with the router?

So far I have read regard NAT it degrades performance as it need to translate every data packet comes from the source and goes to internet. So a question comes in my mind is there any other way how I can share this connection among users with private ip address? Or NAT is the only method to share internet connection among users with private ip addresses?
I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:
0/0 DHCP 10.X.X.X
0/1 192x.x.x

I have a Cisco 2600. I would like to know how to redirect traffic going to a certain IP address three hops away to an IP address on a locally connected segment.
Ex. Packet leaves a device with source IP of 10.10.10.10 and destination of 20.20,20.20 When the packet hits the router (10.10.10.1) I want the router to redirect the destination of 20.20.20.20 to 30.30.30.30 (locally connected segment).
The router has two physical interfaces.I am thinking along the lines of creating a VLAN with an ip of 30.30.30.1 and then doing a NAT translation from 20.20.20.20 to 30.30.30.30.
- How can I connect an old 2600 router to a linksys WRT54G2. to access the internet. I think it is not possible
- What device do i need to be able to do it
We have Cisco IP phones behind a 2600 series router:Most of the time when the PBX receives a packet from the phone, the source IP of the packet is set to the public IP of the router (1.2.3.4) as expected. However, once in a while, we get packets (at the PBX) with the source IP set to the private IP of the phone (10.0.0.12).The router is configured by our provider, and they can't give us any explanation for this behaviour. Is it safe to assume that PAT is not configured properly at the router?
View 2 Replies View RelatedSo I have a 2600 that I have configured three sub interfaces on. FA0.0.1 is set for DHCP and supports VLAN 1. FA 0/0.2 for Voice, FA 0/0.3 for Data. I have this router interface plugged into FA 0/24 on my 3550 and the 3550 is configured as a dot1Q trunk (I have attached configs for RTR and SW).I have most ports configured as access VLAN 1 which is where i have my ISP connection plugged FA0/1 on the 3550. When I connect the service provider link FA0/0.1 never picks up an address. If I take my internal DHCP server and connect it to FA0/1 of the 3550 it snags an address almost immediately.In my mind this validates that my config is fine. I also took the same cable from the service provider cable modem and connected it to my laptop and the laptop is pulling DHCP.

I recently lost my configuration when attempting to reset the password for our Cisco 3560g switch, the switch connects to a Cisco 4506 switch via fiber back to our main office.
I have the switch temporarily routing all traffic to our 4506 by using the default route of 0.0.0.0 0.0.0.0 10.10.10.254 but the same switch is connected to a cisco 2600 router that is on a 10.10.20.0 network and the 3560g is on a 10.0.0.0 network.
Host computers sit on the 10.0.0.0 network, but they need to go to the 10.10.10.0 network for internet, domain, etc the same computers need to go to the 10.10.10.20 for remote connections and other services.
The address of the 3560g is: 10.0.0.254
The address of the 2600 is 10.10.20.2
When the default route is set to 0.0.0.0 0.0.0.0 10.10.10.254 (4560 switch) domain browsing works perfectly
When the default route is set to 0.0.0.0 0.0.0.0 10.10.20.2 (3560G) switch I can ping any ip address in that range and the address on the other
interface ip adresses on the 2600 (eg. 10.10.30.1 / eth2, 10.10.40.1/ eth3 etc.)
I have tried to weight the routes after adding them both to the configuration, but that doesn't seem to work at all.
The switch connects back to the office via vlan1 (10.10.10.253)
The 2600 is connected to port 1, which belongs to Vlan2 (10.10.20.1)
And client computers sit on ports 2-12 belonging to Vlan10 (10.0.0.240)
So in a nut shell, how would I go about setting it up so the machines on 10.0.0.0 can connect to 10.10.20.0 and 10.10.10.0 and vice versa at the same time? Everything was working fine until I rebooted the switch (3560g), which makes me think the person that configured this before me didn't save the running config to the start up config.
I’m working with a managed switch that has three V LANs setup on it. Recently the domain changed and the wireless V LAN can no longer access the internal website. I found access rules, in the switch that allowed the wireless V LAN to use the DNS server on the private/staff V LAN. Their DHCP scope is on the switch and DNS is set there. The Website is also on the V LAN with the DNS server. This configuration totally cuts out external DNS usage. It stopped working though. It is as if when things switched on the Domain the wireless users were denied DNS requests. The switch was not touched at that time. I’m looking at it though and it seems that I may have conflicting rules.
The version is 12.2. I believe its a Catalyst 2600~

However, the “ permit ip any any “ rule, makes all the port rules pointless because when this rule is in place solo, I can ping and access everything on the 192.168.1.0 network. Is there a way to deny everything, except what I permit? Because when I remove the ip any any, then they cant even get out. Perhaps there a better way to say, the wireless users can get out but only get into the sub net over specific ports? I have a feeling it may have not be thought out entirely when initially created. However, the big mystery is that it worked before secondary domain controller failed.

View 5 Replies View Relateddoes Cisco 2600 series switch support 802.1x and DHCP snooping?
View 6 Replies View RelatedMy network generally runs older routers (2600 series) with 16 port switch modules (NM-ESW-16). This has always worked great since I can configure the router and the switch ports on the fly, making changes to either as necessary. Well I am upgrading to 2811 routers, and we wanted to get gigabit ethernet ports on our switch modules. I think I made an error when I purchased a few of these switch modules: NME-16ES-1G.
The first problem, is that the switch ports don't even show up on the router config, I have to establish a session into the switch, (And I can't seem to get back to the router unless I manually switch off power and restart). I don't like this type of switch module, it's like I'm running a completely separate device, and while having a layer 3 switch is cool, It doesn't let me setup routing protocols so I don't like doing it this way. I want to go back to using a switch module that simply adds a ton of ports to my router like the NM-ESW-16. (Note: The NM-ESW-16 does actually work in the 2811 and would be perfect if it were Gigabit speed.)
The seconds problem is that the NME-16ES-1G isn't actually a Gigabit switch. It has a single gigabit port, but the 16 ports are all Fastethernet, and not gigabitethernet. So ideally, I am looking for a switch module that I can fully configure from the router interface that has 16 gigabitethernet ports, and works with a 2811. IE I want to do this. [code]
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?
I need to configure an existing 2600 router to use dynamic NAT for access to the web and ALSO I have (5) fixed IP addresses for use with an email server, a web server, and (3) future servers. I do not know the concept of how to set this up. I'm currently using dynamic NAT for the web and this seems OK but I dont know how to map my fixed servers. I assume this is done with static NAT. Do I need to add sub interfaces on the S0/0 T1 interface for each of these fixed IPs? Then do I somehow do static NAT on these fixed IPs to their respective servers?

View 19 Replies View RelatedI have a /25 block of public ips from my ISP which I'd like to subnet into two /26 blocks. I have a Cisco 2600 with 2 ethernet ports in it. What are the commands I'd need to take my 200.180.200.0 255.255.255.128, gateway 200.180.200.1 and turn it into 200.180.200.0 255.255.255.192, gateway 200.180.200.1 and 200.180.200.64 255.255.255.192, gateway 200.180.200.65? One of the interfaces will be connected to the ISP & the other to a switch, and then we could access the two subnets through the switch.
