Cisco VPN :: 1921-SEC (ISR) / How To Push Route To Client 5.0.x / Change To TCP
Apr 20, 2011
We are using a CISCO1921-SEC (ISR) with IOS 15.1 and we configured a "crypto isakmp client configuration group". We can connect with the "Cisco System VPN Client Version 5.0.07.0410" via IPSec/UDP.
1. Is it possible to push routing informations to the System running the VPN Client ? A the moment all traffic is routed to the tunnel but we like only one route to the network permitted with "pool ..." in the "crypto isakmp client configuration group NAME" section.
2. We searched for changing from upd connection to tcp connection via special port. Is it possible with IOS 15.1 on the CISCO1921-SEC ? Is there something possible like "iskamp ipsec-over-tcp port 10000" ?
LMS 3.2.1, what is the correct baseline template syntax to accomplish the requirement 2:
Requirement 1
• Check if the router is running H323: You can do it looking for the command “h323-gateway voip interface”. If that command is found on a router then it is an H323 voice gateway • Configure the global command: voice class h323 1 [Code]...
I am trying to get the Cisco 1921 to route between 2 LANs. I can ping from the router itself, but cannot ping across either, is there something I am doing wrong here:
version 15.1 ! no aaa new-model ! no ipv6 cef ip source-route ip cef
The router passes the Interface test for the WAN port in CCP but it still we cannot access the internet. Here is my configuration:
Building configuration... Current configuration : 3663 bytes ! ! Last configuration change at 09:29:52 Chicago Mon Feb 20 2012 by fbcpekin version 15.1
We have Cisco 1921 routers that a provider is using for MPLS. They have it configured so that all internet trafic is passed to an internal ip address that is our proxy server. However, they are pushing all of the routing rules down to the workstation which is causing the local route tables to grow to be massive in a very short time.
For example, the second I ping a website, the ip address is resolved and then the route is added for the source ip address with the default gateway of the proxy server.
Is this normal? I would have thought that all the rules would have been handled by the router and let it keep the table entries.
I've got an existing Cisco 1841 connecting to a 10Mbps Internet Leased line. With my current setup I've configured PAT for internet access for my users, and we also have some servers on site which are assigned public ip addresses, these can be accessed from the internet. Now we have procured a Cisco 1921 ISR to replace the old 1841, when I connect the 1921 with an identical configuration in place of the old router, 2 things happen.
1) The users accessing the net via the nat are able to work without any inconvenience (good)
2) My servers which have public IP addresses are unable to reach the internet and subsequently I am unable to reach them via the internet (very bad)
Have cisco router 1921 and 3 cisco switch 3560G i want to configure the cisco router so as network 192.168.4.0/26,192.168.3.0/26,192.168.2.0/26, all to access internet R1921(config)# ip nat inside source list 102 int G0/0 overloadR1921(config)# access-list 102 permit ip ?
I am right to do this below?
R1921(config)# ip route 192.168.4.0/26 10.10.10.2R1921(config)# ip route 192.168.3.0/26 10.10.10.2R1921(config)# ip route 192.168.2.0/26 10.10.10.2
Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?
My ISP has just implemented a new network on the cable infrastructure which uses a PPTP authentication method. It works on my Cisco RVS4000 router as there is an option to set PPTP as the WAN type. The only trouble with the RVS4000 is that the performance is very poor, hence I am trying to get it working with a Cisco 1921. I have looked high and low and I cannot find an sample of a Cisco router functioning as PPTP client to a ISP.Enclosed is the screen shot of my Cisco RVS400 with the options etc.
(Router is ISR 1921)This is doing my head in. I am not using NAT, there are no ACLs, there is no split horizon.Here is what I have. It is practically generated by CCP. When connected I cannot ping the loopback interface or the gig0/0 interface, (not to mention anything else).
version 15.0 service config service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname dcsgw1
we use the Cisco VPN-Client to connect to our CISCO1921 Router and want to go out again on the same interface to the internet. We configured the connection with the IOS scurity package, have no split tunneling - so the client is forced with it's default gateway to our router - we also have pushed our local dns-server to the client and he gets dns results. Now I think we have to got out with some kind of NAT, because our client has a private IP from the IPSec Client pool. At the moment we have no NAT inside/outside, bacause we only use official IP addres in- and ouside (data-room usage).
- Is it possible to get the NAT function going in and out on the same interface with crypto_map IPSec user comming in and going out to the internet ? - Is it more secure to configure this with vrf ? - Has some a link to example configurations for this ?
I'm having problem establish l2tp/ipsec vpn connection from Windows vista/7 vpn client to cisco 1921 ( ios 15.2 ) C1 --------> (internet cloud) ---------> (cisco 1921)----->LAN
Error that I'm retrieving is always the same: Error 789: "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer"
But I'm able to establish l2tp/ipsec vpn connection to the same vpn server with my iPhone 4.
Below is isakmp debug log from lns router(cisco 1921) when I've tried to establish vpn with windows client. Anything useful from these logs to point me on the right direction to finally solve this problem with windows clients.

I have a couple a questions answers on which i cant google for a period. BTW maybe i simly use wrong aproach to choose keywords.
1) Is it possible to assign same ip address to the same client each time it authenticated, preferably without using DHCP? Im definely sure that it possible but cant find corresponded configuration examples (my device is Cisco 1921 with IOS 15.0.1).
2) Is it possible to assign dynamic crypto map to loopback interface (the purpose to make EASY VPN Server accessible through two interfaces - maybe you recommend other approach instead?) - as i move workingcrypto map from phy int to loopback - i cant connect with reason "Phace1 SA policy proposal not accepted"
a) one router with two ethernet interfaces (LANs) and a serial interface. The serial interface is connected to the internet, dynamic nat is used for hosts in the two lans. A web server has a private address of 172.168.50.10 and it is being translated to the internet with serial's interface 68.32.x.x (public ip) with static nat. Clients in the internet type the public address to access the web server.
b)Problem: clients inside the LANs cannot access the web server by typing the public address, they use the server's private address instead, this create a problem with DNS static entries in the HOSTS file in the OS. It is a test server and is only available to authenticated users (lock and key ACLs), so no need to make a real DNS record. The entry in the HOSTS file points to the public address.
c)Question: how can a create a route map to change the public address in the HOST file to the private address of the test web server everytime a user in the LANs type the domain name.
I play a game called Unreal tournament 2k4 in online. I am from Bangladesh a small country from south asia. I used to get 150 ping in a Japanese server. But 2 weeks ago my ping suddenly rise. Now its around 268-320 in same server. But i have 160 ping in another Japanese server. So i used trace-route option from avast IS to check the route of my connection.I found out that the server i am having high ping connects through Italy then to Japanese server. But the server i have low ping goes to Singapore then to Japan.My question is can i change the route of my connection so my first server doesn't take the route of Italy?
I've configured an static route in the ASR1001 router with a name with it eg: ip route 172.20.x.x 255.255.0.0 172.20.x.x 255.255.0.0 name To_system_X.i want to change the name without removing the route.
I have a Cisco router 877. I am trying to configure a backup with ISDN.The primary line is an ADSL over pppoe. The problem is that despite the primary line fails, doesn't change the path and continue going by the main route.I have a very similar setup, also with a cisco 877, but with a normal DSL and it works perfectly.I solved the problem by activating a tracking but is slower than the other method.
I have an ASa 5510 and setup remote dial in users.
I wanted to use the windows 7 built in client and also the draytek site to site VPN options however when they connect VPN traffic will not work however when i use the cisco VPN client then everything works fine.
All the VPN's connect pretty quickly.In the syslog I a getting errors when i try and ping something: [code]
I am having this problem trying to connect to my university network trough the vpn client from a pc running Windows 7 Ultimate 64-bit: the client connects but I have no Internet access. I first believed that the problem was related to the fact that I had ZoneAlarm Free Antivirus+Firewall installed, but I made several steps, including the complete removal of the ZoneAlarm product, and I still have the same problem.
Here's what I see in the log:
Cisco Systems VPN Client Version 5.0.07.0290 Copyright (C) 1998-2010 Cisco Systems, Inc. All Rights Reserved. Client Type(s): Windows, WinNT Running on: 6.1.7601 Service Pack 1
[code]....
Using the same client (32 bit version) in another pc of my lan which runs Windows XP and that had never ZoneAlarm installed on it, I have no problems.Also, using Shrew Soft Vpn Client 2.1.7 on the problematic pc I can connect to vpn without problems, so I am really stuck trying to understand what's wrong with Cisco Vpn Client.
is it possible for a client to choose a WAN to use when being routed through a Multi-WAN router? Something that could be configured as default route in linux or default gateway in winxp ?Or is this decision totally up to the router itself ? [code] Could now a client on the subnet 192.168.0.0/24 choose 1.1.1.1 as a default route for example? And if not, could this be possible if the router hat some secondary internal IPs for both WAN interfaces.
I have a 2900 ISR that my VPN clients connect to using IPSEC over UDP. I am having periodic problems, especially with clients connecting through DSL, where they connect and immediately drop. Sometimes this is resolved by users updating their home router firmware. I'd like to issue a new client PCF file using IPSEC over TCP to see if that resolves the problems.
Can I have both running at once, and what do I need to add to the 2900 to enable this connectivty without breaking the existing clients? If the test is successful, I will migrate all users to the new configuration. This ISR is also used to support L2L connectivity for a handful of sites.
I have an Airport Express and two wireless routers. The Airport Express is connected to Router 1 via Ethernet. Router 2 is connected to Router 1 via Ethernet. Since I like to know which Wireless Router I'm connected to, Router 1 & 2 use different SSIDs. Router 1 is the DHCP server (DHCP turned off on Router 2). All security settings are turned OFF.Router 1 is a Linksys WRT120N with latest firmware and Router 2 is a Belkin Wireless Router.I can connect via wireless to Router 1 and Router 2 via the seperate SSIDs and have Internet connectivity (Router 1 is connected the the Internet) and print to a wireless printer connecter to the Router 1 wireless network.
Now here is the strange thing. I can see the Airport Express only if I connect to the Router 2 wireless network!!! I cannot see it if I connect to the Router 1 wireless network, yet the Airport Express is connected via Ethernet to ROUTER 1 !So for some reason, the LinkSys WRT120N Wireless Router won't route the Airport Express to a wireless client on it's own wireless network, but it will route it to an Ethernet client which is what any client connected to Router 2 wirelesslessly is seen as. When connected to router 1 wirelessly I can ping the IP of the Airport but something is preventing it from working with iTunes/iPhone/Airport Utility. It is bizarre because these are all devices connected to the same LAN. SInce I can ping it, it tells me that it isn't a routing issue, but there must be some sort of filter between the wireless and ethernet that is preventing the Airport protocol from being transmitted.
i have a strange issue with an HSRP Setup. I have two (S1+S2) 3560 as Core/Distribution Layer. Inter-vlan routing are enabled on both Switches. S1 and S2 are connected with an ether channel over four fibre ports. S3 -S5 are the (L2) access layer.
Gi0/1 on S1 and S2 are L3 ports, connect to a Linux Firewall.
HSRP is enabled, S1 is the active router and the STP root bridge.
But, my monitoring via cacti show me, that the Gi0/1 on S2 is active, too! But it should not be active? Only if S1 fails, should S2 the active switch.A client from the access ports on S3 - 5 gets traffic from the Internet via Gi0/1 from S2. Gi0/1 on S1 is active too, but will send mostly traffic to the Internet. Why is S2 active and why route it traffic from the Internet to the client?
I recently downloaded DDWRT to my DIR-615. I was trying to change my DIR-615 from a router to a client bridge but I was not able to get any internet connection on the device after I change the settings.
We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability delay down 1 up 1 ! track 20 rtr 2 reachability delay down 1 up 1 ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?
For access by external users on our network use all Cisco VPN Client, we have a VPN3000 Concentrator and a Cisco ACS 2.6 for authentication.We wanted to upgrade to the latest release of ACS 4, x .... you can set a password expiration for VPN Client? Or make sure that the remote user can change password?
I have a curious issue on a customer site where the above components are installed.The issue being that the iPhones the users utilise cannot connect to the mail server via WiFi, they are forced to connect with their 3G connection. The core issue seems to be the 887VA, as when I've installed 'lesser' branded ADSL routers, the connection seems to be fine.The iPhones are set to access the mail server via the URL: mail.customer.com. Should I change this to the internal IP of the server 192.168.12.200, the mail connection works fine. However I cannot expect the client to make this change every time they arrive or leave the office. Presently I have them disable WiFi when on premises.
We are using an ASA 5520, running 8.4(3). We have users running the AnyConnect Secure Mobility Client 3.1.02026. I have the AnyConnect connection profile configured to authenticate users using LDAP over SSL. I enabled the password management and am able to get password change prompts to appear in the AnyConnect client. However, new passwords are rejected and changing passwords through that prompt does not work. I'm not sure what the cause of the problem is, since LDAP over SSL is enabled and working, which is required for the password management feature
Is there a way to change the timeout for the Client Excluded: MACAddress status? It seems like the exclusion is rather short. I'd like to have the ability to control the exclusion time. Using WLC-5508 7.0.116.0.
Using LMS 3.1 in win 2003 SP2. Recently experiencing a problem, not able to fetch/push config for the n/w devices. I deleted and re added the device to lms and found able to perform the task. There was no connectvity issue during the problem.
