PIX IPSec tunnel - IOS, routing Options

Hello

I have an IPSec Tunnel between a PIX firewall and a router Cisco 1721.

Have I not all options about any routing protocol can I use?

Are there plans to add GRE support to PIX, so that EIGRP, OSPF can be used?

------Naman

Here's a URL that tells how to configure GRE over IPSEC with OSPF. http://www.Cisco.com/warp/public/707/gre_ipsec_ospf.html

Road by default from version 6.3 PIX IPsec tunnel

We have a PIX 501 running IOS version 6.3.1.

There are currently 3 tunnels IPsec active as described below.

What we would like is to have all traffic by default (0.0.0.0 0.0.0.0) range out through the tunnel of the middle line so that traffic can be protected by a firewall on the other side of the tunnel. Since ICF is a Sonicwall what would be needed to be changed in the configuration on the PIX to get there?

Thank you

Hello

You do not configure really any type of default route for the VPN L2L. You match rather traffic with 'everything' destination on configuring VPN L2L. Basically you would like to configure the VPN L2L ACL encryption with the 'whole' destination map

I guess in your case it would be the ACL named "103".

access-list 103 allow ip 10.10.5.0 255.255.255.0 any

IP 10.10.5.0 doesn't allow any access list 103 255.255.255.0 10.10.1.0 255.255.255.0

Naturally, your NAT0 ACL configuration should also reflect this change. I guess the end remote Sonicwall'd private NAT to public Internet access in this case whereas. I guess that in this case, the ACL NAT0 might even be just this one rule ACL

access-list 101 permit ip 10.10.5.0 255.255.255.0 any

BUT what I was asking however for now mainly is the fact it has a priority of '11' in the 'crypto map' which has between 2 other L2L VPN connections.

peer11 card crypto ipsec-isakmp 10

correspondence address 10 card crypto peer11 102

peer11 card crypto 10 peers set 75.95.21.41

peer11 card crypto 10 set transform-set pix11

11 peer11 of ipsec-isakmp crypto map

correspondence address 11 card crypto peer11 103

11 peer11 peer Sonicwall crypto card game

card crypto peer11 11 set transform-set pix11

12 peer11 of ipsec-isakmp crypto map

correspondence address 12 card crypto peer11 104

card crypto peer11 12 set peer 75.62.58.28

card crypto peer11 12 set transform-set pix11

If you have changed the destination address of '103' crypto VPN L2L ACL at "" I guess that would probably cause so that the last connection VPN L2L with "12" priority may stop working since the previous connection already corresponds to 'all' your network 'inside' destination address.

The solution might be to delete the current configuration of the '11' priority and add it with '13' for example, so that the other 2 connections VPN L2L could continue to work and all the rest of the traffic would be passed to the connection VPN L2L with Sonicwall as the remote peer.

No crypto map ipsec-isakmp 11 peer11

no correspondence address 11 card crypto peer11 103

no set of 11 peer11 card crypto don't peer Sonicwall

No peer11 11 set transform-set pix11 crypto card

13 peer11 of ipsec-isakmp crypto map

correspondence address 13 card crypto peer11 103

13 card crypto peer Sonicwall peer11 game

card crypto peer11 13 pix11 transform-set game

I have to say that this is how I expect it should work. I worked with VPN L2L that have been configured in this way but its quite rare.

If you want to try something like that, of course, be ready to return to the old configuration with your admins of the remote peer, if things do not work. I guess more difficult configurations changes must be made on the remote end while your configuration of the ends should be fairly simple.

Hope this helps

IPSEC tunnel and Routing Support protocols

Hello world

I read that IPSEC does not support routing with VPN's Site to the other protocols because both are Layer4.

This means that if Site A must reach the B Site over a WAN link, we use static IP on the Site A and Site B router?

In my lab at home I config Site to Site VPN systems and they work correctly using OSPF does that mean that IPSEC supports the routing protocol?

IF someone can explain this please?

Mahesh.

Indeed, solution based purely crypto-card are not compatible with a routing protocol. Crypto card however is the legacy config we support on IOS. The best practice is to use the protection of tunnel. Any routing protocol would work then.

for example

https://learningnetwork.Cisco.com/docs/doc-2457

It's the best solution we currenty have

IPSec tunnel on router from closure

Is it possible to get a VPN IPSec tunnel on a router from the loopback interface? If so, how?

Hello

Yes it is possible. The command is:

card crypto-address loopback

Please make sure that the loopback interface has a public IP address that is accessible.

verification of IPSec on IOS / router

is there a way to check Cisco router syslogs an IPSec tunnel is established with another Cisco router / peer? I've been looking at manuals system (DRY, events Crypto) Message and sees that things that would indicate problems - would be able to verify syslogs to validate that a tunnel came without a problem, or if a tunnel down, etc. but not sure what these messages look like.

Thank you

-randy

Randy, now I understand!

What I would do in this case is a number of things, but it must again some minor configuration on the router, it depends on the managed router provider, but... you should be able to ask the provider know that you want to get traps syslog from the router to your syslog server and they should be able to provide this and they should provide that After all, you pay for the services, even if is a router that is handled by the provider.

On the router thye should set up a secondary server logging.

e.i

say that your syslog server is 20.20.20.20

Router (config) #logging 20.20.20.20

trap to Router (config) #logging of information

the foregoing information is facilitated #6 on the 7 levels of ease, 0 being emergency 1 critical alerts 2 and so on... I think with this # info tunnel facility appears in the syslog.

In addition, on the access lists on the tunnel Ipsec-L2L add the log keyword at the end of each of its access-list, with the journal of Keywork, the router will send traps related to the access list to your syslog, providing you with as well as the connection is stablihed or not.

Hello

PIX 6.3 code supports the two RIP (v1 and v2) and OSPF. The disadvantage is that you cannot configure the RIP and OSPF on the same PIX. You must choose the one that you want to use. I hope this helps.

NAT in the IPSec tunnel between 2 routers x IOS (877)

Hi all

We have a customer with 2 x 877 routers connected to the internet. These routers are configured with an IPSec tunnel (which works fine). The question is the inbound static NAT translation problems with the tunnel - port 25 is mapped to the address inside the mail server. The existing configuration works very well for incoming mail, but prevents users from access to the direct mail server (using the private IP address) on port 25.

Here is the Config NAT:

nat INET_POOL netmask 255.255.255.252 IP pool

IP nat inside source map route INET_NAT pool INET_POOL overload

IP nat inside source static tcp 10.10.0.8 25 25 expandable

IP nat inside source static tcp 10.10.0.8 80 80 extensible

IP nat inside source static tcp 10.10.0.8 443 443 extensible

IP nat inside source static tcp 10.10.0.7 1433 1433 extensible

IP nat inside source static tcp 10.10.0.7 extensible 3389 3389

allowed INET_NAT 1 route map

corresponds to the IP 101

access-list 101 deny ip 10.10.0.0 0.0.0.255 192.168.1.0 0.0.0.255

access-list 101 permit ip 10.10.0.0 0.0.0.255 any

On the SAA, I would setup a NAT exemption, but how do I get the same thing in the IOS?

See you soon,.

IOS router VPN Client (easy VPN) IPsec with Anyconnect

Hello

I would like to set up my router IOS IPsec VPN Client and connect with any connect.
Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

Please let me know how if this is possible.

Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

But I am in any way interested in using IPSec and SSL VPN on a router IOS...

It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

The configuration guide (here) offers detailed advice and includes examples of configuration.

Tunnels of router that support s multiple VPN IPsec AND SSL VPN

I have a main office and an office, each with a RVL200 connected via the IPSec VPN tunnel. We grow faster than we thought and add 2 more branches. Is there a router that is similar to the RVL200 can I put in my main office in support of multiple IPSec tunnels connected to RVL200 in branches, but also keep the SSL VPN?

It seems that the Cisco ASA 5505 will do.

Deployment to connect on a router that is already running an ssh IPSec tunnel

I have a bunch of routers that have been made (by someone else!) with Internet IPsec tunnels to the base, but with a telnet vty access network. It must be updated so that only ssh is available for use vty.

Its pretty easy to deploy ssh, but part of the task is to generate an encryption key, "generate the rsa encryption key" etc, if I try to do the configuration without this command, I get an error message asking me to do.

And there is the problem: when I generate a key, it screws the existing IPsec tunnel somehow. Worse still, is not do so immediately, he's waiting for an indefinite period, probably (I guess) until after the tunnel IPsec has been idle for a period and has stopped/started, while I * think * is happening is that on the re-opening of the tunnel, he picks up the wrong key, and the other end kills the link. Newspapers have nothing relevant in them, and I always try to have the failure occur on a router running the debugging.

Has anyone tried to do this before update? should we put ssh first, and then rebuild the config of IPsec tunnel?

Thanks for your ideas/comments

Jim

If the IPSec VPN using certificate authentication, RSA keys regeneration may be bad. Without knowing your IPSec configuration, I would say that the best approach would be to generate an SSH key that will not interfere with it. Try something like this:
```
 crypto key generate rsa modulus 2048 label RSA_Key_SSH ip ssh rsa keypair-name RSA_Key_SSH
```
This will generate a new key, which is independent of any existing keys and configure SSH to use.

How to disable a particular IPSec tunnel on Cisco router

Hi guys,.

Someone knows a way to termporarily disable an IPSec tunnel on a Cisco router provided individual:

-No configuration changes

-Without affecting the other IPSec tunnels running

-GRE is not used, so there is no tunnel interface to close

Or in any event nearest to you to meet the requirement above?

Thank you

Andrew

Andrew,

There is no way to 'turn off' the tunnel without changing the config.

I think the easiest would be to get the card crypto for this particular tunnel and remove the peer or the ACL:

for example:

labmap 10 ipsec-isakmp crypto map

no counterpart set 10.0.0.1

labmap 10 ipsec-isakmp crypto map

no correspondence address 100

or you can remove the key isakmp for this tunnel, that would, for example:

No cisco123 key crypto isakmp 10.0.0.1 address

That would prevent the tunnel to come without affecting the other tunnels.

I hope this helps.

Unable to Ping hosts through IPSec Tunnel

I have a configuration of lab home with a PIX 515 running code 8.03. I've made several changes over the last week and now when I finish a VPN connection to the external interface, I'm unable to hit all internal resources. My VPN connection comes from a 10.22.254.0/24 trying to knock the internal nodes to 10.22.1.0/24, see below. When I finish a VPN connection with the inside interface works, so I guess that I'm dealing with a NAT problem? I have not idea why Phase 9 is a failure:-------. Any help would be great!

ASA 8.6 - l2l IPsec tunnel established - not possible to ping

Hello world

I have a problem of configuration of the CISCO ASA 5512-x (IOS 8.6).

The IPsec tunnel is created between ASA and an another non-CISCO router (hereinafter "router"). I can send packets ping from router to ASA, but ASA is NOT able to meet these demands. Sending requests of ASA is also NOT possible.

I'm trying to interconnect with the network 192.168.2.0/24 (CISCO, interface DMZ) premises and 192.168.3.0/24 (router).

The CISCO ASA has a static public IP address. The router has a dynamic IP address, so I use the dynamic-map option...

Here is the output of "show run":

Do you have an idea that I am wrong? Probably some bad NAT/ACL I suppose, but I could always find something only for 8.4 iOS and not 8.6... Perhaps and no doubt I already missed the configuration with the unwanted controls, but I've tried various things...

Please, if you have an idea, let me know! Thank you very much!

Hello

I've never used "global" option in ACL, but it looks to be the origin of the problem. Cisco doc.

"The global access rules are defined as a special ACL that is processed for each interface on the device for incoming traffic in the interface. Thus, although the ACL is configured once on the device, it acts as an ACL defined for Management In secondary interface-specific. (Global rules are always in the direction of In, never Out Management). "

You ACL: access-list extended dmz_acl to any any icmp echo

For example, when you launch the ASA, there is an echo response from the router on the external interface--> global can block.

Then to initiate router, the ASA Launches echo-reply being blocked again.

Try to add permit-response to echo as well.

In addition, you can use both "inspect icmp" in world politics than the ACL.

If none does not work, you can run another t-shoot with control packet - trace on SAA.

IPSec tunnel is disabled

We have 3 IPSec tunnel set up between the cisco 1760 router and PIX 515e. IPSec tunnel is down by intermittent & son come only after compensation isakmp crypto & clear crypto its next to the router.

do we need to configure something else in router and end of pix so that tunnels are still in Active state (QM_IDLE).

Looks like the PIX loses its connection and the router is unable to say that the PIX has dropped.

Try the isakmp keepalive on both devices configuration but also check network links extended features.

See you soon,.

Policy Nat and IPSec tunnel

Hello

I have a Cisco IOS router and you want to configure an IPSec tunnel between myself and the client. Unfortunately, we have two overlapping of 10 network IP addresses.

Is it possible for me to just Nat addresses IP on my side or should the customer Nat as well?

I have configured NAT on the inside of the interface for 10.134.206.1 to 192.168.156.6 so that Nat happens before that packages are encrypted in the tunnel, however tunnel is not coming. The client uses a sonic firewall and allowed their 10.91.0.0/16 network 192.168.156.0/24.

See attachment

Kind regards

They are wrong to installation. Remote local networks are not 10.134.206.0 and 10.134.206/42. It is simply your public IP address.
