I'm having trouble setting up a Cisco 2801 as an internet router between our firewall & our ISP.I've setup FastEthernet0/0 as the WAN port & FastEthernet0/1 as the LAN port. I've setup a default gateway pointing the next hop (the ISP),when I plug in a pair of laptops configured to mimic our IP scheme, I'm able to ping thru, but when I put the router between our firewall & ISP I'm not able to get out to the internet (can't ping google) I can still ping the next hop.,Our old router died, so I am unable to pull up its configuration. Here is the code I'm come up with so far.
One of my internal servers requires it to be available to the internet I am having a hard time allowing it to be NATed through my Ciscc 2801 router. It seems as though im missing something small. From what I can gather it seems as though its as issue with ACL, but im not sure. I have ran the following command: ip nat inside source static tcp 192.168.5.1 ***WAN IP Address*** 8443 extendable Then I tried to add it to the ACL via this command: access-list 150 permit tcp any host ***WAN IP Address*** eq 8443
Here is a copy of my config.
IP 172.19.3.x sub 255.255.255.128 GW 172.19.3.129 Ciscso 2801 Router
The goal is to add a 2801 router between a DSL modem and a switch and obviously still access the internet. I connected and configured as explained below and the results are:
- I am able to ping internet addresses from the 2801 router - I am not able to ping internet addresses from userlaptop but I am able to ping LAN gateway (192.168.254.254)
I cannot understand why the internet requests from the user laptopuser are not routed to the internet but the router itself can access the internet.
Currently we have a cisco router 2801 for Wireless Internet connection. And we are going to have another ISP that can provide us Fibre Optic internet connection rather than wireless.My question is that can we use this router for fibre optic internet connection? how do we go about this? what is the maximum bandwidth that the router can support?
I want to set up my LAN to have internet access via my 2801 router.The 2801 router is connected to my home ADSL router.Now do I just configure a 0.0.0.0 'gateway of last resort' on the 2801 router pointing to the interface leading to the ADSL router ?Therefore, all traffic from my PCs that is internet bound will head out to the ADSL router and onto the internet.
I am working on Videoconferencing solution between two location. locations are now being connected through IPSEC site to site VPN. Since we are having a common internet link for VPN as well other corporate use we have to prioritize the internet bandwidth for Videconferencing. is there any way i can prioritise videoconferencing traffic by ports? following are the configs done on the cisco 2801 router with Version 12.4(15)T10.

Im trying to set up a wireless router in my dorm room. I know, I am not supposed to do that. I got it set up and everything, but still didn't have internet access.
Just moved into apartment in Ann Arbor and am forced to use this ISP. They are not wireless friendly. Their manual sucks and will only provide tech support for $80/hour. I bought a Belkin router and got it working for my MacBook. BUT my roommate can't connect, even tho her MacBook sees the network. And I can't print to my wireless printer even tho it says everything is fine when I run the wireless diagnostics.The ISP has these rules:
- Only connect the router to the Internet or Wan port. Do not connect to the numbered ports (how do I know whether or not I've done that?) - Do not use static IP addresses - Do not run a DHCP server
I live in an area that has no cable or dsl internet available.The only options are basic dial up or wireless internet through one of the cell phone companies.Right now I use verizon with a usb adapter.I have had this since moving here.It gets good speed and I share it witht the other 4 pcs in my house through a 5 port switch using windows xp's ics(internet connection sharing)We mainly use the internet for playing games together online.Recently though i have wanted to upgrade to a wireless network.I feel as if I 'm living in the stone age because everyone else I know is using wireless.Last night I went out and purchased a netgear n750 duel band router(model number wndr4000-100nas) after reading several guides online about how to set it up.It sounded easy enough but after 3 hours I still could not get it working.
Here is what I am trying to do.I want to basically turn the router into a switch by disabling it's routing function and let the pc that has the verizon wireless card be the host and hand out ip addresses to the other pcs.(like it is doing now)Problems I am having
1- keep getting the work offline popup when I click on anything in the router control panal(it say you are not connected to the internet would you like to connect or continue to work offline I hit work offline and it just pops up again when I click something else)
2- I think I found how to change the router's ip address and disable DHCP under lan controls but when I hit save it pops up saying I need to manually change my pc's ip address and it will not save.
I am using winxp32 sp3 and right now 5 gigabit wire lan cards.(though if I get this working I'm going to pick up wireless card for 4 of the pcs.)
What I'm trying to do is create a private network for local file sharing but also have internet access. There is a WRT54G router connected to a satellite modem in a separate building, just barely close enough to connect from my laptop, which is what sparked my original idea to use my WRT54GL as an access point.
Due to the way I have my DSL and VOIP TA configured I need to be able to set the subnet mask in the Internet connection. I am currently using the Static IP, putting in an IP of 192.168.1.x with the subnet of 255.255.0.0 when I try to do this it gives me an error saying that 192.168.33.1/255 is reserved for the guest network. I am not using the 33 at all ANYWHERE. If I change the subnet to 255.255.255.0 it will save but I can't connect to the internet with it. My router I just bought today is the E2500 I have an old Linksys WRT model that worked fine with this exact setup for several years before it crashed on me.
I looked but could not find any information on what's the use of the USB interface on my 2801 router. I saw something about Cisco USB memory module and eToken by Aladdin. Is this interface restricted to Cisco and Aladdin only?
I have a Cisco RV110W small business router setup at my home. It has one of those HTML GUI interfaces, check the boxes, etc.., to get things working. Basically, your typical home router with VPN. I have enabled the VPN, it's PPTP, added the password, and now it's automagically configured! I can successfully VPN to my home with a Windows7 client. Here's my problem, I now need to VPN into my home router with a 2801. Is this possible? Everything I found on the subject has only been to setup a Cisco IOS router as a VPN server or tunneling to another IOS router. No examples using an IOS based router as the client.
We have one Router Cisco 2801 at the customer site and facing issue of having very High CPU coming to 99%.CPU utilization for five seconds: 99%/28%; one minute: 99%; five minutes: 98%
I have to configure failover on both router. if one get fail then the other router should be dial.Physical connection
•1. Two routers (Cisco 2801) are connecting with splitter through RJ 11 port. •2.Only one ISP link is coming in splitter.
Requirement: As per as customer requirement. He wants redundancy with in both 2 routers. If one goes down then the other router come up. And same configuration on 2801_R2 router. I am planing to do HSRP on our lan network (2801R1,2801R2 ehternet interface which connected to switch). from switch i will create two default route with (next hope) virtual ip address.
I have a 2801 router with a HWIC-3G-cdma card that I have inherited from a predicessor. How to use a cellular card on a router and need to get this thing up and running. Any example config that I can see or point me in the right dorection to get this up and running? I have the cellular card set up as Cellular0/1/0 on the interface, I assume that that was done by default, and it has an IP address. The Static Route of 0.0.0.0 0.0.0.0 Cellular0/1/0, in the config with only 2 other interfaces as being direct connection. But that is as far as I recognize. Do I need to set up a router protocol? Which one? How do I use the cellular card? Do I need to have an ISP connection?
I have just received Time Warner Cable and get 16Mbps down from them directly through their modem (motorola DOCSIS 2.0 modem- SB5101) to my PC (using speedtest.net). When I then connect TWC's modem through my 2801 router on fa0/0, the download rate I get is considerably slower (on the order of 3-4Mbps via same testing method). What am I missing?
Here is how the passthrough interface is setup:
interface FastEthernet0/0 bandwidth receive inherit ip address dhcp ip nat outside ip virtual-reassembly in duplex auto speed auto
I have attempted removing bandwidth command - nothing changed with it not there. I have also hard coded the speed and duplex to 100/full to no avail....
Other possible relevant configs: ip nat inside source list 1 interface FastEthernet0/0 overload ip route 0.0.0.0 0.0.0.0 dhcp access-list 1 permit 192.168.1.0 0.0.0.255
Basically this things is wide open... for testing but the download speed differential is perplexing to me.
I need some clarification if it is possible to do an IPL connection between Cisco 2801 (T1) to Cisco 1841 (E1) via Ethernet (2801) to Serial (1841).
I am unable to find any documentation about this and I need to connect our network to our overseas office.
Our side uses the 1841 router and our provider has set-up our E1 connection to be via Serial interface while on our overseas office uses the 2801 and will connect via the T1 card, which by the way does not have any serial interface ports just ethernets.
So far checking on how to configure this, I am unsure on how the connection will happen since the info that I got is that T1 does not have the option to hold an IP address (also unsure on this though). With this in mind and that the 2801 does not have serial interfaces, does that mean that IPL connection would be via the available Ethernet ports?
I have 5 routers. Four routers are: c2801-IPBASEK9-m v 12.4(24)T2. One router is a C2800-IPBASEK9-M v 12.4(24)T3. so, it appears that the IOS on all 5 routers is very similar, the only difference is the T3 at the end of the version and that 4 are 2801s and one is a 2800. What is very wierd is the 4 2801 have the embedded scripting language "tclsh". The 2800 does not have tclsh. If I issue the command: tclsh on the 2800, I get:
Center-GW#tclshTranslating "tclsh"
% Bad IP address or host name% Unknown command or computer name, or unable to find computer addressCenter-GW#
I have problems with the Router 2801.When i give the command show processes cpu, the command show me that the router is working in 98%.
I have vlans like voice vlan and others, I have one 20 Mb Wan Link and I redirect all traffic from my lan to this link and when i browse in internet or i do downloads the router goes to 98%, when i don't make it the router processes goes down.
I thought be problem with hardware, but i exchange to another router and the same problem happened.Before this situation, I had one link with 12 Mb and nothing happened, when i exchange this to the 20 mb link the problems starting.
I have one problem doing a ping to a router lan interface, I have 3 routers (2801) connected between each other (separated 1 mile each), the link is established trough microwave signals (connected to the 2801 fast ethernet interfaces), every router has a connection to a LAN. One of them is located at headquarters.Last thursday I replace one of the router with a cisco 2901, i configure the router with the same configuration that was on the 2801, i power up the router and the 2 link were up without problems.One day after the noc called me to tell me that after i replace the router they can't ping the router IP lan interface on the new 2901 (before the replacement the ping was sucessful). I called one user the lan connected to that 2901, and they can do a ping to the router's LAN IP address.
I can ping the 2901 IP wan interfaces, I can ping the LAN users ip address, but i cannot ping the router LAN IP address, from my desktop, and neither the 2 routers 2801 connected to the 2901.I show the configuration on the 2901, I couldn't change it because i didn't have time to do that, but i'll change the configuration to use ipsec tunnels.The configuration as you can see, has a crypto map, but the acl used by the crypto map, only permits the interfaces ip address, so i think that doesn't work, so the traffic doesn't get encrypted, but i don't know if that is the problem why i can't do a ping to the lan interface. [code]
I'm using for a company network a 2801 Cisco Router. This router has 2 FastEthernet Interfaces connected on 2 ISP's and one VLAN for internal users. What acl should i use if for example one client from the lan is using a torrent client to download from the internet. I want just to specify a maximum download speed or to block that client to access the internet when it's trying to download something that can affect other clients from the LAN.
When i start a download the processes of the router cpu stay in 99%/97%. When i'm not doing a download the processes stay in 3%/0%. I have one 20 mb link to Wan.
I did the troubleshooting seeing the this document :
simple configuration of a 2801 Router. I have 2 internet providers with static ip's connected to F0/0 and F0/1 and one Vlan for LAN area. I would like to configure the router to use one primary line and just in case to use the back-up line. [code]
Now if detects that it hasn't cable link on the FastEthernet interfaces it's working. I'm using 2 wireless gateways to acces the internet each one connected on the 2 FaEth for simulating the providers. If i simulate an issue on the provider ( i've removed the sim from the wireless gateway) it doesn't pass on the second isp.I haved trying to configure with "IP Service Level Agreements " for failover / load balancing but the command "ip sla" is incomplete. I can't make an update of the IOS because the customer do not have an Service Contract with Cisco.
I have setup an eBGP session to a Cisco 2801 CE router. The BGP session establish, however, the session keeps resetting after 90 sec which is the BGP keepalive holdtime value.
On the PE router I found that the OutQ doesn't clear = 22 when doing a "sh ip bgp x.x.x.x summary" - Session reset at 1:30.When I filter the amount of routes advertized to the CE neighbor with the "neighbor x.x.x.x prefix-list out" - I see the OutQ clear = 0 and the BGP session remains up.
-Number of NRLI advertized without prefix filter = 172 -Number of NLRI after filter = 52
Earlier today I attempted to change the setting on my Westell 6100 modem such that it would simply bridge the connection to my Linksys WRT54GS router, basically involving setting the router to bridge only and turning DHCP off. Now I no longer get an internet connection through my router when previously the connection had worked perfectly fine before. I following the steps of cloning the MAC address to the router and have done the proper resetting steps (computer, them router, then modem) but I simply can't get an internet connection through my router. The process to set up simple bridging from the modem what supposed to end up with the internet light no longer turning on but the light turned back on following one of the resets.
Currently, I can connect to the internet through the modem just fine but I get nothing when I include the router. I'm not sure if there are some other settings I'm supposed to be changing as I can't seem to find anything past what I've already done when researching online. At this point I would just be happy reverting the settings I've changed but I don't know how to access the modem now that DHCP is off.Basically, I'd prefer to be able to get the router working with these new settings but if that proves too difficult (as I've heard it can be when trying to get Westell modems to work with Linksys routers) I'd like to learn how to access the modem and change the settings back to what they were (preferably in as simple terms as possible as I don't particularly understand what a lot of these settings/configurations do).(And a bit of an aside, but I had attempted to do this modem bridging to "fix" perceived internet speed problems. I've been averaging around 300Kbps download rates ever since I've had this internet connection from Verizon when the supposed download rates should be between 1MB and 1.3MB. Doing this modem bridging had been reported to fix some modem/router conflicts and improved connection speeds for some.)
We have a cisco 2801 router in class which has a disabled password recovery. We tried almost everything, we cannot get into ROMmon and the break sequence doesn't work in any program (hyper terminal, putty, teraterm pro).

I have a 2801 router that I am replacing with a 2911. I know the ports on the 2911 are Gigabits and the 2801 are Fe. I read where the IOS would not support backup and restore on each other . I am attaching a show ver on both routers. I need to know if backup and restore would work and or what other changes would need to get done.
