Cisco VPN :: 891 Router With Two Internet Feeds Both Doing IPSec VPN
Apr 12, 2012
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?

The multicast sends out fine and is received by the distant end modems fine but the distant end router sees the same source in the RPF and picks the lowest IP address neighbor to use so the router only picks up two of the four feeds.

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?

Got a situation where Location_A got TWO ISP and Location_B got One ISP.Using ISP 1 link Location_A establishes IPSEC Tunnel with Location_B .How do I establish redundancy from Location_A point of view, if ISP1 is down then ISP2 should establish IPSEC tunnel with Location_B.At Location_A both ISP links terminates on the cisco PIX-525 and all (VPN) crypto configuration is on PIX 525 running version PIX Version 7.2(4)7At Location_B VPN is terminated on a PIX Version 6.3(3).

I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

setup CE500-24TT switch Port FE2 router / ports FE1,3-24 desktop / Ports GE1-2 Switch ports - MAC filtering is NOT enabled

G1 - Empty
G2 - 8 port Gig Switch
8 Port G Switch = SBS2008 / Win2003 with Citrix / Win2K8 Management Server - plus a couple of desktops for Gig to server accessIs it possible to configure a PIX 501 to allow internet access for a Cisco VPN Client 4.8 without Split tunneling.The idea would be to have all raffic traverse the tunnel, be routed out the local WAN link on the PIX and then have the reply be forwarded back to the client over the IPSec tunnel.

we have a cisco ASA 5505 and are trying to get the following working:
vpn client (ip 192.168.75.5) - connected to Cisco ASA 5505
the client gets a specific route for an internet address (79.143.218.35 255.255.255.255 192.168.75.1 192.168.75.5 100) when i try to access the url from the client i get a syn sent with netstat when i try the packet tracer from the ASA i see the following:

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:

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 configured Ipsec vpn tunnel beetween two routers (from site A to site B) over untrusted internet connection by cisco 3825 routers and i can successfully access both of this routers. But now i need to access internet on site B router sitting on site A router. So that if i run traceroute from A site machine then the gateway by which internet passing through shows the ip of site B.
The Architecture of our both site routers :
Site A 10.1.11.0-----Router A 172.18.12.1-----VPN tunnel----Router B 172.18.12.2-----Site B 10.4.11.0

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.

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 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.
