Cisco VPN :: IPsec VPN On 871 Router
Sep 27, 2011
I have a cisco 871 router and I have set up an IPsec vpn on it. I can connect to the vpn but once connected I can only ping the router (10.12.0.1) but nothing else on the network. I can access the router via ccp/telnet and from the router I can ping other machines on the network, so I know that they are connected, but I can't access them from the vpn connected machine. Also the vpn connected machine can't access the internet while connected to the VPN. How can I get computers that connect via the vpn to see other machines on the network, and how can they access the internet while connected to the vpn?
Here is the running config:
Building configuration...
Current configuration : 6760 bytes
version 12.4

I tried any type of combination and just couldn't make it works. Only PPTP works well. Whether Apple iOS IPSec VPN is supported or not?

I have a 5510 running 8.42 code with multiple site to site tunnels coming into it. Sites vary from ASA 5505's, 1841 and 1921 routers which all work perfectly. That being said I think the ASA side is good. I have an 837 running 12.4 code, Cisco IOS Software, C837 Software (C837-K9O3SY6-M), Version 12.4(5b), I'm trying to configure it for site to site VPN back to the ASA. When I ping from the E0 interface I get the following debug output and nothing else. I've made a lot of changes to no avail in getting closer to a successful configuration. [code]

I have been struggling for a few days with getting site-to-site traffic working across a L2L IPSec tunnel. At this point, I have the tunnel up, and I see packets being decrypted on the correct IPSec SA's when I ping from a local network computer on the ASA side to a local network computer on the router side. I cannot ping from one side to the other, but those packets are getting through. We have another L2L tunnel that is from that ASA to another remote site's ASA, and that is functional. I have mirrored the configuration for ACLs, etc. from that site, so I believe that the issue is with the packets getting incorrectly translated by the NAT/NONAT statements/ACLs on the router side.

I recently purchased a 1941W Router and upgraded it to IOS15.2T. After upgrading I was disapointed to see that it didn't have IPSEC VPN capability. What do I have to do to get this support activated/installed on this device?

We have set up a site to site IPSEC VPN between a Pix 515E running 8.0 (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and ASDM on the pix to build the initial tunnels. Now the site with the router is changing to a Dynamic IP address from the ISP so we have set up Dynamic DNS to update the dynamic IP address.
The problem we have is that ASDM will not allow us to set a domain as the peer address, it will only accept an IP address. We think the solution will be to remove the static Crypto Map and replace with a Dynamic Crypto map on the Pix side. Our questions are simply; is this the best solution? can we edit the original static list or is it better to delete and make a new dynamic crypto map? Is there a short cut to change the config in command line? This is a live network so just want to check before we make changes on live kit.

We are trying to setup a router with two internet feeds both of them doing IPSec VPNs back to a single peer...one of these VPNs is for VOICE traffic and the other is for DATA traffic...we have a default route set out one Internet feed which is the primary feed used for outbound browsing and the data vpn. The only other routes on this router are two static routes for the destination private subnets at the remote end but pointing to each feeds respective default gateway...I would have thought this would work, but only the data vpn is coming up and the voice seems to stay down due to not having a proper route?
If I set a static route for the remote peer out the voice internet feed, then the data vpn would drop...should I apply a policy based route on each of the inside interfaces, voice and data, setting the ip default next hop to their respective default gateways?

I'm trying to make a redundantish office/datacentre connection on the cheap. At the datacentre, we've got a 7301 (12.2(24)T5) and at the office we've got a Mikrotik RB1200 (5.12).The office router has two ADSL connections to two different ISPs, the datacentre router a single GigE to a colo provider. I'm trying to build an IPSec encrypted IPIP tunnel over each ADSL service to a separate loopback interface on the datacentre router, so I can run OSPF over the top for route exchange. I need to use two different loopbacks on the datacentre router so the office router can have a static route for each out each ISP ADSL. But I'm running into issues making encryption work on two different source addresses.Using the 'crypto map xxx local-address Loopback12' command, I can specify the outbound interface for one of the tunnels just fine, traffic moves as expected - while the other tunnel fails to encrypt. But is there a way of having two peers use two different local addresses, or applying two crypto maps to a single physical interface?

I am configuring Remote Access IPSEC VPN in IOS Router 12.4T.I am able to establish IPSEC VPN from VPN Client 4.0. But I am able to access all the LAN machines from this client connected.I want to restrict access to only one server in my LAN rather than accessing all the servers in Datacenter.For example
-Group FTP should be able to access only FTP Server with ip addess 10.1.1.21 on Port 21
-Group WEB should be able to access only WEB Server with ip address 10.1.1.80 on Port 80

I have a connection between HQ and Branch which connected by GRE tunnel over IPSec. I use Cisco router 3745 that has IOS version: 12.3(18) and Cisco router 2911 that has IOS version : 15.0(1r)M9 with ipbase, security and data license.
I tried to apply command to both routers as follows:
Cisco 3745 (HQ)
crypto isakmp key test address 10.1.1.2
crypto isakmp keepalive 60
crypto ipsec transform-set myset esp-3des esp-md5-hmac
crypto map vpn01 local-address Loopback0
[code]....
When I appied this command that will show a notification as below:
NOTE: crypto map is configured on tunnel interface. Currently only GDOI crypto map is supported on tunnel interface.
*** After appied this command, I cannot ping or send any traffic to HQ. ***
I use this command that is working normally on Cisco router 3745 that has IOS version: 12.3(18) and Cisco router 2811 that has IOS version : 12.4(7b).

I am doing my college project(Client Server Chat Application in C#). I need to transfer all the data of my application through a VPN tunnel. I want to create a IPSEC VPN tunnel through which I can route the Data. I am low On budget I am not inclined towards buying any Hardware. So is it necessary to purchase a Router or a Network Interface Card To create A IpSec VPN.

I am configuring a vpn ipsec tunnel with cisco isr 2921 router and Watchguard edge 1250e. I have the watchguard configured so I just need to make sure I have everything setup on the cisco side. At this point, there is no communication as I am not sure if I configured it correctly. Should I do the crypto map on g 0/0 or dialer 1?

I'm having some problems getting an ipsec tunnel established between a cisco 887VA router and a cisco srp527w router.I am working from a few text books and some example materials. I have worked through many combinations of what I have got and am still struggling a little bit.I look at debug results and it appears as though the policies do not match between the devices:
Jul 23 05:44:37.759: ISAKMP (0): received packet from XXX.XXX.XXX.XXX dport 500 sport 500 Global (R) MM_NO_STATE
broute1#
Jul 23 05:44:57.079: ISAKMP:(0):purging SA., sa=85247558, delme=85247558
broute1#
Jul 23 05:45:17.031: ISAKMP (0): received packet from XXX.XXX.XXX.XXX dport 500 sport 500 Global (N) NEW SA
[code]....
Some specific questions:
1) on the SRP in the example's I have used (and I have a few SRP->SRP VPN's that work) I see you need to enter the preshared key, I'm not seeing in the examples I have used anything about the IKE preshared key on the IOS box. Any examples where you use the preshared key for IKE? I wonder if this is my primary issue as it states clearly in the log that there is no Preshared key :|
2) I have used a mish mash of names between the various sections as on the SRP the naming convention isnt the same; ie: which parts of the IPSEC negotiation come from the IKE policy section and which from the IPSEC policy section. Do the names really matter across different ends of the VPN?
3) I notice when I perform this command in the(config-crypto-map)#:
set peer FQDN
It is converted to:
set peer XXX.XXX.XXX.XXX
Is this expected? I want the device to look at the FQDN as this particular host is using DDNS and not use a static IP address.

Problem: IPsec VPN setup seems ok (Client to gateway) but is not responding from client requests. However, remote manage works, PPTP works.
My environment:
Hardware: RV016 10/100 16-Port VPN Router
Firmware: v4.2.1.02 (Jan 18 2012 14:10:55)
Clients: Mac OS X 10.8 (integrated VPN client) , Windows 7 (build in VPN client) OR both with NCP-E VPN client.
None of the above works with IPsec. I have tried all kinds of combinations. I don't think the problem is wether I use Group1 or Group2 or DES or AES...It must be something else... Neither of the built-in VPN (IPsec) clients in Mac OS X or Windows can be configured in an easy way. BUT the NCP-E client can. I have tried to set it up to exactly meet the settings on the server but no progress...How do I setup an IPsec VPN group so that I can use any of my VPN clients to work?
PS. I have also tried the client that comes delivered. 1- It does not work and 2- it's only available for Windows.

I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

Having some issues with a vpn between two of my locations. Both edge devices are ASA's, and the tunnel is an IPSEC tunnel. Both MTU's are set to 1500 both on inside and outside. (provider mtu setting request is 1514, and both ASA's will be changed out soon.) Unfortunately, some exchange/kerberos auth issues are causing me a problem in the remote site. I perform the tests that microsoft recommends using a length of 1472 on packet ping size, and do not fragment flag (1406 is the largest packet I can push across the vpn) . I know part of this is due to the extra overhead that ipsec places on the connection.
I want to refrain from putting the black hole registry workaround on all of the PC's in this remote location.I've also seen some discussion about manually setting the TCPMSS value down to 1300 on most ASA's.

We have a main and branch office, each with an RVL200 . I configured both with static IP's as provided by my ISP, yet when I try to do a test connection on the IPSec screen I just get that it's "waiting for a connection" in the cell third from the left. Both RVL200 's are connected directly to the modem/bridge supplied by both ISP's.

I'm currently in the market for a new router that supports remote IPSec VPN access to my home network. The router must support wireless (latest "n" standard is a plus) and must have gigabit links for LAN at least. I have been considering the following two routers but neither has an IPSec VPN server built in to the router OS:
ASUS RT-N66U
MikroTik RB2011UAS-2HnD-IN
As far as I can tell they both have PPTP server functionality and only IPSec pass-through. I would like a router that has the server ability built in to the OS so I won't have to run an additional system behind my network edge. I can also look into any small to medium size business routers, just as long as it supports a majority of the same features of the two routers I have listed for comparison.

I have a Linksys E2500 Firmware Version: 1.0.03 and am using the "IPSec Passthrough" for work. On a typical day I'll sign in to my work's VPN, do my work, sign off in the evening, and read my personal email with a direct connection to the internet.
Then on the next morning, I am unable to connect to work until I go to http://192.168.1.1/index.asp and click "reboot." And as soon as the modem finishes rebooting, my laptop can connect to work. I've tried this several days in a row now, and indeed all I need to do to get the VPN passthrough working is rebooting the modem.
Nothing under "Applications & Gaming" is set. I've seen some posts about having a trigger on UDP port 500, but I'm not quite sure how to translate it for the E2500. Plus I'd rather the router "just work" day after day for VPN and everything else, like my old router did! Is there some other setting to try or clearer directions for a bulletproof IPSec passthrough on that unit?

We have used two Cisco RVS4000 to create the IPSec VPN between the main office and the branch office. The main office has SBS 2008. There is a Windows Server 2008 as the domain controller in the branch office. One branch office user has a laptop which is not in the domain, but his exchange account is set up in the Outlook. When he connects the laptop to the branch office network, he cannot connect to the exchange server and get the emails. Is there any configuration to set up in the router, server or Outlook?
