Cisco VPN :: VPN Access To FWSM LAN Through A 2801
Mar 26, 2011
I have a FWSM in my 6509, this firewall is managing three VLANs, one of which holds a file server. As you all know, FWSM do not support VPN like the ASAs and PIXs do. I have been trying to add remote access to this file server LAN all week. The only VPN device i have is a 2801 router.
first layout: VPN router behind FWSMstatic translation from FWSM LAN (private) to VPN WAN (public)default route was facing back at FWSMip address pool was to be NAT'd on the interface facing the FWSM the idea was that my VPN address pool would be NAT'd back to the FWSM on it's VLAN. since the FWSM was managing this VLAN and recognized the source IP of the translated address pool, i would have access to my precious file server.
second layout: VPN router fa 0/1 on a /30 with 6509 (public)VPN router fa 0/0 still on the same LAN as FWSM (private)address pool for VPN once again NAT'd to fa 0/0default route pointed to fa 0/1static route of FWSM LAN pointed to fa 0/0 this idea was to have more of a 'inside' and 'outside' interface on the VPN router. this too did not work, having used every trick in the book, i could still not ping anything on the FWSM LAN while VPN'd in the network (aside from the LAN interface on my router)
trace route was showing that the all routes were headed out fa 0/1 (default route) and all to my FWSM died. i really don't think my address pool is being NAT'd, though my route map statement applied to the NAT policy is permitting my VPN address pool.
I am new to VPN technology, one of those things that happened to land on my lap. how this layout could work? there are no good VPN Remote access walkthroughs for a situation like this (2801 allowing access to a FWSM controlled LAN)
I was trying to setup an Remote Access VPN using ISR 2801. I was able to establish the vpn tunnel from my house using DSL Connection (behind NAT), the ISR give the IP address which is from the ip pool that I configured on the ISR. The problem that I have right now is that it fails reaching the corporate LAN network.
I have a 2801 router. Is there another way to deny access to a specify web site ( like youtube, facebook .. etc ) without create acl's with specifed ip's ? The router doesen't support url filtering. I thought to do something like redirect traffic to another site : for example if one client want to access url.. that the browser will open url...
I am having an issue where I cannot access certain files on websites. It looks as though the files are accessed via ftp. Could my router be blocking it. I have a Cisco 2801 router acting as a firewall.
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.
I was just recently hired in my company, we have an sf300-24p switch but I cant find the console cable for it, I think it needs a female to female db9 serial cable, all I have is a DB9 serial to rj45 console cable for the 2801 router, also I cant find the IP address of the sf300 switch, it is directly connected to the 2801 router, I issued a show arp to the router but didnt find the switch's IP add for web access, to sum it up I have no way of configuring the switch, is there any way to find the IP address of the switch? It also dosnt show on show cdp neighbors?
We are running a FWSM and have created ACL's for a new Lync install. One of the rules needs to have port 5061 access from any source to our front edge server for communication. When looking at the logs I see a hit on the ACL but nothing ever actually connects.
One possible issue I see is possibly in the inspect: policy-map global_policy class inspection_default inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect sqlnet inspect sunrpc inspect xdmcp inspect sip inspect netbios inspect tftp inspect pptp class class_sip_tcp inspect sip
In the inspect sip this is only for port 5060. How do I set this up to allow port 5061?
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 have very strange behaviour on my Cisco 2801 router when I applied access list on wan interface.
Architecture:
SIP Provider <----> Cisco 2801 <-----> CUCM 6
Problem:
We are using Cisco 2801 as Voice gateway for CUCM 6. so only one purpose of this router is just receiving calls on sip dial-peer and transfering to internal network.
If you look on access list below, if 'log' words don't present on these 2 lines, access list didn't work. Problem with it is that when I establish call from us or to us I can't hear incomming RPT stream, but other side can hear me. But when I type word 'log' there, everything stars working immediately.
I need to enable Management access to FWSM using CA ssl certificate.
FWSM Version 3.2(5) in Cisco 6509 switch.
Got to know how to generate, import and export certificate but my query is how to get it applied to the management ip do i need to apply in the management interface.
I am having FWSM in active /standby mode deployed on two different cat 6k chassis. Unable to access the fwsm module from switch using ' session module mod_no processor 1 ", it throws error " % telnet connections not permitted from this terminal" Running Version 3.2.6 on fwsm, Cat 6k is running 12.2.33.SXH1,
switch#session slot 3 processor 1 The default escape character is Ctrl-^, then x. You can also type 'exit' at the remote prompt to end the session % telnet connections not permitted from this terminal ---------------------------------------------------------------------------
have allowed telnet on line vty, configuration on Line vty is simple allowing all transport protocols
line vty 0 4 exec-timeout 5 0 transport input all transport output all line vty 5 15 exec-timeout 5 0 transport input all transport output all
Today i received FWSM from cisco (RMA), I need to configure it as standby unit for existing FWSM active/standby setup.
IOS on RMAed FWSM is 2.3.4 and cisco VSS supports FWSM IOS 4.0.4 and later.My issue is, I cannot access FWSM (IOS 2.3.4) via session command from cisco 6513 but could successfully consoled it without any problem. I have reloaded it twice and also tried to disable and enable power on it.
VSS#sh module switch 2 Switch Number: 2 Role: Virtual Switch Standby Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 -----------
[code]....
why I cannot access FWSM through session command ?Whether this is because of older IOS ? If yes then how to upgrade its IOS ?Is it possible to upgrade IOS via FWSM console ? if yes, Do i need to test on different slot ?
I am trying to remove a line in a particular access-list configured in a FWSM module using this command "no access-list <acl> line 19 x x x x" but it doesn't work. See below:
FWSM/xxx03(config)# no access-list ? configure mode commands/options: alert-interval Specify the alert interval for generating syslog message 106001 which alerts that the system has reached a deny
[code]...
How can I remove a line from the access-list without clearing the entire access-list?
I have a Cisco 2801 with dual ADSL WAN connections, PATing to a network hanging on the fa0/1 interface. From the server connected to the router (hanging off of the fa0/1) interface, I can ping any address and there are no issues. But from inside the Cisco CLI, pinging certain addresses causes erratic behavior. [code]
I have a 2801 router. The Fa0/0 int shows up/down. I have plugged it into diffrent cisco and non cisco switches and even a cross over cable to my laptop. I cant seem to get the protocol up. I have changed the speed to 100 and duplex to full to try to get it up that way and nothing. [code]
I have a 2801 with dual ISP connections, and I have configured route-maps to direct voice traffic over ISP1 (working just fine), and I'm attempting send all other traffic over ISP2 (traffic is load-balancing instead). The connection to ISP2 is DHCP, and I have configured a route-map to route this traffic using the 'ip next-hop dynamic dhcp' command, but when I look at the route-map, it states the following: ip next-hop dynamic dhcp - current value is UNKNOWN..Is there something that I need to enable in order to see the next-hop, and properly send traffic over the ISP2 connection? [code]
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 2801 with flash: c2801-advipservicesk9-mz.124-16.bin where I use to doing VPN IPSEC.My problem is where I do a connection with a client, if my VPN dont have a traffic, the tunnel are closed. If a receive or send any traffic, the tunnel get up again.If don't have traffic, this tunnel is closed and after is opened other tunnel where is changed the conn-id to 999 for example.This comportament is normal? Exist a form that my tunnel never close? I enabled the parameters below: [code] But the tunnel continues closing if a don't have traffic.
We are setting up a new VPN from an ASA to a cisco 2801 router (behind a third parties checkpoint firewall). We seem to be almost there with the setup but the tunnel is not working correctly. I have included a debug from the 2801 router and its config and a diagram of the setup. [code]
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%
The only QoS command i have in global config is (no MLS qos) :
REMOTE-ROUTER1(config)#qos ? restore-show-output Restore old show output shape-timer Set the HQF shape timer interval
The router is running IOS:
System image file is "flash:c2801-ipbasek9-mz.151-4.M5.bin"
Am i just running the incorrect IOS or am i missing somehting, i need to change the QoS Map for my Nortel VoIP. The VoIP phones connect to a 3750 PoE which used to conenct to a 2651XM to route VoIP and data traffic over the same copper pairs (WAN link to hub site) hence the need for a Service policy but being Nortel phones, require changing the cos-dscp map. the 2801 is going to replace the 2651XM using a new HWIC.
We have a 2801 rotuer in place that hooks up to a metro ethernet link that's obviously dropped off to us via ethernet. Anyway, the throughput granted to us is 20MB, but for some reason I can't get it to go anything above 11MB at the most. I've spent a day going through documentation trying to find the fastest speed the 2801 supports and I can't find my answer. I've seen that the high speed wan cards in this router support up to 45MB, but I'm not using a WAN card, only one of the two built in 10/100 ports.
i have configured remote access vpn on my 2801 router's gio0/0 int ip x.x.x.1. i connected my laptop through vpn client from internet. i connected successfully and my vpn router gives me the assigned ip block y.y.y.1. from my laptop i can ping the other int gio/1 ip z.z.z.1 but i cant ping the ip z.z.z.2 of my core sw which is connected on router's int gi0/1.
The application here is a wind power project, built in two phases, without any effort to coordinate or integrate the two sites during the design phase. All operations activities for both phases are performed by one staff out of a common location. This is a rural area and Internet connectivity is mission critical due to contractual obligation with Electrical Utilities.
The client has a need to reconfigure a network which has grown over time in a layer by layer approach, whereas at every point in time that an additional T-1 or other changes occurred to address a specific need, no thought was ever put into integrating the entire site as a whole. It is at best a dysfunctional solution which somewhat accomplishes thier needs, and at worst, a kludgy, grossly security compromised, and difficult to use infrastructure. There is every kind of equipment one can imagine, each installed by some entity providing needed services on the site, but forced to make uninformed decisions because the client really has no IT department to coordinate with. Over time, every vendor just provided their own switch, router, or maybe figured out how to reconfigure another existing device to also provide the routing or access needed, To say the least, it's a mess.
The client requests a solution which provides a means to accomodate 6 internet connections (4 T-1 lines, and 2 satellite) in a manner which aggregates available bandwith and provides redundancy. The T-1 lines will be the main internet access, with the satellite connections only used if available bandwidth falls below some threshold, say 3Mb. There are many internal networks which need to be routed to and between, in total, about 20 subnets. There are 2 SCADA (Control) networks which have a mandatory requirement of 1Mb each, a VoIP system which does not use any internet connetivity as there are 6 POTS lines dedicated to it, an internal office LAN and a turbine manufacturers site LAN.
The T-1 lines, at 1.5Mb x 4 = 6Mb.
The 2 SCADA networks require a guaranteed 1Mb each, the remaining 4Mb is to be allocated between the office LAN and the turbine manufacturer site LAN. The satellite connection are only to be active in the event bandwidth falls below 3Mb.
There are 2 Cisco 2801 routers on site which could be reutilized if appropriate. Each T-1 has it's own Adtran CSU with Ethernet out. All T-1 lines are /29 IP Blocks. 2 of the T-1 lines are adjacent IP Blocks, for what its worth.
Everything here is open to reconfiguration. The client wants this finally integrated correctly with the ability to address emerging Electrical Utility cybersecurity requirements in the immediate future.
An ideal solution would be fully redundant to eliminate the single point of failure at the edge router. As to whether there needs to be separate edge and interior routers, I just don't know that. I would guess everything could be done with just a pair of redundant routers at the edge, but perhaps it is better to do the interior routing between subnets on a different router(s).
Again, the goal is a well integrated, redundant, and secure solution. My part is mostly complete, with the OSP part of the network finally at 100% after 5 years of stupid and careless misconfigurations and bad fiber splicing (by others).
I'm absolutely covered up in business at Layer 1 & 2 on these sites, as the physical plant and associated network elements are typically very poorly designed, specified, and implemented. The complexity of this job leads me to seek outside advice and ultimately a more qualified Cisco professional than me. I'm experienced enough with Cisco to know when I'm in over my head. I know a diagram would be nice, but at this point I've only got a very detailed diagram which reveals too much site identity information to make public. I'll wait to see a few comments and in the meantime work on removing site identity info so I can post a good diagram for everyone to see.
Someone told me the commands, but I can't remember them. Have a router (2801) at the end of a highly utilized T1 link/router. How do I protect it so my SSH and/or Telnet sessions will get serviced if the router is real busy.
I've been looking and I can really find much info about this, I got a 1841 and 2801 router with ADSL WIC cards and both are synching really low compared to my cheap home router
This leads me to believe I need a firmware update so I got the adsl_alc_20190.bin and loaded it into flash and reloaded my router but its still saying my firmware is using an embedded one.

I have a nat and vpn setup on my Cisco 2801 router.Everything is working as expected except the NAT. I have a single static nat translation but it only works for inbound and not outbound. Going outbound, it uses the default overload nat address of the outside interface. [code] I want to add another mailserver. But I fear if one mailserver were to get black-listed, they would both be reporting there ip address as the same address (the one on the ethernet interface) which would blacklist both mail servers.Again, inbound nat works ok, but outbound is just using the IP of the ethernet0/0 address.
I have a cisco 2801 router, My ISP in which i receive my bandwidth from has assigned me a ip address/gateway etc for my FA0/0 from our Telco switch. I need to figure out how to bridge through the public ip scheme they are issuing me through FA0/1 (setting up a transparent bridge) so in example if i was givin 192.168.1.189 on a /30 network for my router (assigned to FA0/0) how to i set it up to bridge through the publics?
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.
