We have Cisco router 2851 and asa firewall. We configured on he router for IP phones and ISP connected. The ISP directly connected on the router and asa firewall connected to the router. We have plan to configure VPN on the router. We have available public ip address. if i configure the VPN on the firewall we need to configure firewall local ip address to public ip address. SO how to configure firewall local ip to public ip ? Where we can configure , mean on the router or firewall. Firewall and router configuration.
One of our client has a Cisco IOS router 2851 with Zone Based Firewalls, enabled.
We tried to configure the router to receive the logs and we receive it in the following format: <189>45: *Apr 11 11:22:14.757: %SYS-5-CONFIG_I: Configured from console by vty0 (10.151.xxx.xxx)<190>46: *Apr 11 11:23:13.109: %FW-6-DROP_PKT: Dropping tcp session 10.151.xxx.xxx:1908 212.58.xxx.xxx:80 due to RST inside current window with ip ident 0<189>47: *Apr 11 11:38:02: %SYS-5-CONFIG_I: Configured from console by vty0 (10.151.xxx.xxx)<190>48: *Apr 11 11:40:57: %FW-6-DROP_PKT: Dropping tcp session 10.151.xxx.xxx:2062 74.115.xxx.xxx:80 on zone-pair Outbound class CMAP_Inspect_Out due to Stray Segment with ip ident 0
However, we support the following format:

What are the exact steps required to recieve the above format? If the logging needs to be enabled on Access Lists, need exact commands, from the console config mode?
I am having a setup with a 2851 router & websense url filtering server where I need to forward the traffic to websense server for all the internet requests. The http traffic is getting filtered properly, but the https traffic is not getting filtered. The two commands I ahev given for http & http are as follows: ip inspect name test http urlfilter ip inspect name test https.
I have a request for blocking urls using a class map. I have made this work with HTTP, however it does not work for https. This is a 2851 router with IOS Version 12.4(15)T7. I see i could use the command "match protocol secure-https" however this does not let me specify any specific urls.
Does a new IOS version will support what I'm trying to do? Or if there is another way?
We have a new 50/10MB Comcast Deluxe connection we are trying to set up in our environment. We have a single static IP and the Comcast provided SMC-3DG router/modem has been set to "bridge mode" by Comcast. This is then plugged into one of the interfaces and that interface has the static IP defined on it with a default route to the Comcast provided gateway IP. I wired the 2851 into our layer 3 switch, set up some static routes on the 2851 back to our existing subnets and everything traffic-wise is flowing between our existing subnets and this new router.
Since the default route on our layer 3 switch is defaulted to our older 2811 router (that I'm intending on replacing with this 2851), I set up a static route on our layer 3 switch to guide all traffic for speedtest.net and comcast.speedtest.net out to the 2851 router. Doing speed tests show 12 MB down, .5 MB up. Connecting a laptop directly to the Comcast SMC modem and setting it's IP to the static IP shows full speeds again, so the issue has to be with our configuration/equipment.
Can a Cisco 2851 support this 50mb Comcast connection and do I just have it configured wrong? Or do I need a different router altogether? At first I tried the 2811 but that had slow speeds, so I figured the 2851 with twice the throughput would do a better job but for some reason it is not currently. I have played with duplex settings (100, full, half, auto) and nothing changed. I updated the 2851 to the latest 12.4 firmware and also no change.
Is the 2851 router meet these requirements ? if no. What is the must specific series of the routers suitable for this requirement:
1. Comprehensive interface range supporting T1/E1, NxT1/E1, FE, and High-Speed WAN . 2. Wide array of Layer 2 access protocols including Frame Relay, Ethernet, and PPP/HDLC . 3. Rich and granular QOS and instrumentation for prioritizing mission-critical traffic such as voice . 4. A modular platform with a broad range of interface options. 5. Network Address Translation (NAT), and IP Sec . 6. Four (4) auto sensing LAN Ports (10/100/1000) Mbps built-in routed ports. 7. WAN Interface Slots (4-6 option Slots) . 8.

I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.
[URL]I ran across this on the cisco site and I wondering if it was possiable with two 2851's? The part that is most interesting to me is this part of the config (this looks like what allows the use of the y-cable)
Network newbie here asking an embarrassing question on logging We have a Cisco router with the following IOS version. I want to enable logging; so do I need to configure event-log enable before adding the following logging configuration?
I'm just wondering if there is any documentation that confirms if the 2 built-in Gigabit ports on a Cisco 2851 router support (or otherwise) auto-mdix.I can find information for the modules but not the 2 built-in ports.
We have Cisco 2851 Router part code CISCO2851-SEC/K9 facing issue while set peer configuration, issue description below.
Issue:We are facing the problem while configuring set peer as when we try to this we face error like 'unable to set peer.maximum numbwe of peer (40)exceeded'
We suspected the IOS issue hence we have gone for IOS upgrade for this Router but this error is still coming while configuring set peer.
Previous IOS: c2800nm-advsecurityk9-mz.124-15.T7.bin New IOS:c2800nm-advsecurityk9-mz.124-24.T7.bin
We are attaching here the snap shot of error that is coming while configuring the Router with set peer command along with show tech of the Router to understand this case brief.
Cisco Router 2851 connected with one ISP using 2 serials. the case is :
1)s0/0/1.1 is the only utilized and s0/0/0.1 utilization is zero. 2)when shutting down s0/0/1.1 : the other ,not utalized, link work perfect and forward all the traffic.
Attached the configuration file with output of show interfaces command.
We have a Cisco 2851 router that crashes every night. Below is the 'show log' output. The provider is telling us that it is our equipment. We have replaced the router and still have the same problem. Is it our equipment or the provider?

I have a Cisco 2851 (c2800nm-advipservicesk9-mz.124-25d.bin) Router configured with one site-to-site vpn. Is it possible to configure a failover vpn tunnel on this router?
Do I need to obtain license keys/files when upgrading a 2851 to IOS 15.x? I'm getting a bit confused seeing the documentation that says 1) IOS has gone to a universal image and 2) that feature sets are unlocked based on the installed license.
I was able to download a feature specific IOS image for the 2851 and it did not bother me about licensing upon boot up.
I read one post on here that stated 2800/3800 series (G1) do not have to worry about the licensing piece and that it's just 2900/3900 series (G2) hardware that require it.
I seem to be having an issue getting a 3xT1 bonded solution to work. I can get 2 out of the 3 T1s to come up and pass traffic, but I can not get the third one to be added to the solution.
Up to today I used Verizoon 4G to a Windows Visata box running Internet connection Sharing to get my home lab connected to the Internet . All was working well.
Today I had Hughesnet come and installl their service and I can no longer get access to the Internet from my PC netowrk. my VPN to my office for my IP phone coomes up an works just fine. At the router I do have Internet access which then leads me to believe that my problem is NAT related.
My router is a 2851.
When I enter PING 4.2.2.2 I get !!!!! but when i enter PING 4.2.2.2 SOURCE 192.168.69.3 I get .....
I have a Cisco 2851 (with a 4 port switch module) that I am trying to set up with two different internet connections, and have it route traffic out to them based on the source IP. One connection is a 50mb Comcast connection, another is our T1 that our servers are hosted on. The goal is to guide server/phone system traffic to the T1 and have the rest default to the Comcast. I currently have the 2851 connected to our Layer 3 switch (Dell Powerconnect 6224) with a subnet created between them. Static routes have been created on the 2851 back to all of our existing subnets. Traffic flows internally without a problem between the subnets and 2851 (and vice versa). I set up the 2851 with route-map's in the NAT to control the flow of traffic, with the default route set to the Comcast connection. Default route works great, speedtest shows full speeds and everything looks great. The problem happens when I apply my route-map policy to the internal LAN interface with the ACL list of IP's that I want to guide to the T1 (with a next-hop of the T1's IP address). I tested some tracert's and pings from one of the IP's in this list and they would stop at the T1 modem and not go any further. I did a "show ip nat translations" and noticed that the "outside" portion (right half) was blank for every IP that was in the ACL or related to the T1. So my guess is it looks like this is not doing NAT for the T1? I double-checked that I had my "ip nat inside" on the LAN interface and "ip nat ouside" on the T1 VLAN interface and Comcast interface and they were there.
I am having issues bringing up a tunnel between a cisco 861 router and Cisco 2851 router. Tunnel has been dropping every week atleast once or twice. Usually router reboot fixes it but today it is just not coming back up. have updatee remote, reloaded the config still no use. It seems like it is partially coming up but I see the following two messages on the main router:
1- Death by retransmission P1
2- 11:03:03.789: %CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE packet from 12.234.109.169 was not encrypted and it should've been
I have checked the config on both routers it is the same as the VPN was up and we didn't make any changes on either of the two routers.
I have Cisco 2851 router & need to allocate bandwith based on IP's. eg. 192.168.1.1 should use 7 Mbps & 192.168.1.2 should use 2 Mbps & 192.168.1.3 should use 1 Mbps. Let me know the configuration on how to execute it on a router.
I am looking to add a new connection between a Cisco 2851 and a Cisco 3745. Currently there are two T1 connections between them for a internal 192.168.5.0 network but I would like to add a ethernet connection to give a larger pipe for when transfering large files via that network. Can I just add the ethernet to the multigroup and shut the ethernet connection down when not needed(to limit it to t1 speeds) or is there some other way of doing this?
I currently have a 2851 router with 2Mbps point-to-point leased circuit on its serial interface and most of the time its congested. Any tool for measuring the current consumption that is happening on the link other than netflow.Was looking for something for a graph or chart displaying the current consumption rate.
I was making some changes in routers and after I rolled back configuration a gre tunnel won't work. It's GRE Tunnel between a Cisco 7600 and Cisco 2851.
It seems like 7600 sent packets unencrypted. On C2851 is received this message:
%CRYPTO-4-RECVD_PKT_NOT_IPSEC: Rec'd packet not an IPSEC packet. (ip) vrf/dest_addr= /10.0.0.10, src_addr= 10.0.0.18, prot= 47
I am setting up a lab network to emulate our production network and am using a single 2851 to emulate both my MPLS provider (only running BGP, not actually running MPLS) and our ISP that we use for our DMVPN secondary network.
Because I am using one router to function as both service providers I am running VRF's to keep the routing tables separated. So far basic connectivity works fine, I can ping from the PE 'MPLS' VRF to the data center CE interface and the ISP side is working as well.

HQ-HUB is the only site with access to the Internet.
So if Site1 or Site2 or Site3 need to access the Internet, traffic will have to go through HQ-HUB and from there reach the Internet.I have routes 2851's on the spoke sites. Which command or mechanism you would explore in this case to make the spoke sites point to the HQ-HUB to reach the Internet?
Would you do this based on DNS settings or getting an access-list & static route defining when the spoke routers traffic need to go the internet, point to the HUB-HQ as the default?
