5 routing VPN site

Hi all

I threw myself little in this project without a lot of lead in. Basically, we have 5 sites

Site A: HQ with ASA 5520

Site B: Remote with 5505 with L2L at Site A

Site C: Remote with 5505 with L2L at Site A

Square D: distance with 5505 with L2L at the Site

Site E: Remote with 5505 with L2L at Site A

In an emergency, I had to get phone running systems when a T1 PTP line was cut at the beginning by the customer! I created a VLAN on each phone named 5505 and created the Tunnels of VPN L2L all return to the HQs 5520. Everything was good in the neighborhood, phones were talking about main PBX server to HQ, we could compose and in no problem. The problem is now the phone Vender tells us that we need routing between each site. We cannot compose between each remote site without using external number (whereas before you dial internal extensions in order to reach all other sites)

Site B needs to talk to the PBX to C, D and E (A, obviously as well but that is already at work) and so on.

I found topics dealing with 2 remote sites requiring a routing, however, with 4 that all need to routing to the other configs will very quickly very vast and complicated. There is already extra virtual private networks to of the HQ 5520 who go elsewhere and a good amount of security configurations, so the config is already pretty decently sized.

Is there a better way to do this, or should I start to write my setups now?

If I understand your question, you need to configure a list of VPN networks on each VPN Ray and the hub.

For example on the RADIUS B a crypto access list that is similar to:

ip-> A B permit

ip-> C B permit

ip-> D B permit

ip-E > B permit

corresponding Cryptography ACL on the hub for talks would be like:

IP-> B to allow

IP C-> B permit

allow the ip D-> B

E-> B ip license

Repeat for each Department accordingly.

So basically your configuration crypto would ' t grow, only the ACL crypto.

You can work with groups of objects to simplify the ACL crypt, in this case:

Crypto ACL on Hub B:

object-group VoIP-dst

object A

object C

object D

object E

object-group VoIP-src

object B

permit ip src VoIP VoIP-dst

And so on...

Just make sure your config allows same-security-traffic intra-interface

Route VPN site to site on one path other than the default gateway

I want to route VPN site-to-site on one path other than the default gateway

ASA 5510

OS 8.0 8.3 soon

1 (surf) adsl line interface default gateway

line 1 interface SDSL (10 VPN site-to-site)

1 LAN interface

What's possible?

Thank you

Sorry for my English

Here is the assumption that I will do:

-Your IP SHDL is 200.1.1.1, and the next hop is 200.1.1.2

-Your LAN-to-LAN ends on this interface (interface card crypto SHDL)

-VPN peer 1 - 150.1.1.1 and LAN is 192.168.1.0/24

-VPN peer 2 - 175.1.1.1 and LAN is 192.168.5.0/24

This is the routing based on the assumption above:

Route SHDL 150.1.1.1 255.255.255.255 200.1.1.2

Route SHDL 175.1.1.1 255.255.255.255 200.1.1.2

Route SHDL 192.168.1.0 255.255.255.0 200.1.1.2

Route SHDL 192.168.5.0 255.255.255.0 200.1.1.2

Hope that helps.

Router vpn site to site PIX and vpn client

I have two on one interface on the pix vpn connections that terminate VPN. client vpn and VPN site-to-site have passed phase one and two and decrypt and encrypt the packets. However as in another post I can not ping through the l2l vpn. I checked this isn't a nat problem a nd two NAT 0 on the pix and the NAT on the router access lists work correctly.

I looked on the internet and that it points to a routing error when packets are being encrypted and decrypted, but you can't do a ping on the binding. However when I test the connection I did not enter any of the static routes that networks are connected directly on each side of the pix and the router. any help would be a preciated as I think there's maybe something is blocking the ping to reach the internal network at the end of pix with a configured access list.

is ping failure of the only thing between the site to site VPN? and assuming that all other traffic works fine since it decrypts and encrypts the packets.

If it's just ping, then activate pls what follows on the PIX:

If it is version 6.3 and below: fixup protocol icmp

If it is version 7.0 and higher: select "inspect icmp" under your political map of the world.

Config complete hand and on the other could help determine if it's a configuration problem or another problem.

Router VPN site-to-site recommendations

Hello

I have to configure a VPN tunnel between the main and branch offices of a (very) small business. Is there a broadband internet access in both sites through cablemodems ethernet. ISPS assign the two dynamic cablemodems IP addresses public, which means that they are accessible from anywhere.
In fact, it is a very simple task. My question is:

What is best Linksys/Cisco equipment for this configuration of small businesses, as both routers should have in addition to the functionality of server VPN wireless capabilities?

I thought to of the Linksys WRTxxxN, but they don't VPN (they are public devices in any case). Then I thought of the RV042 appreciated, but there is no wireless unfortunately.

I'll highly appreciate recommendations. Remember that routers are for a very small company, so they should be prices accordingly.

Thanks in advance,
Fernando Ronci

E-mail: [email protected] / * /

Cisco Small Business has several VPN wireless routers, that supports site to site VPN.

WRV210 and WRVS4400N are older models, while R120W and RV220W are of newer models. You can find pricing information on the sites of e-commerce as CEP, newegg, amazon or buy.com.

If you have the double condition of WAN, for example, the increased reliability of internet connectivity, adding a point of access (for example WAP4410N) wireless R042 might be a good choice.

VPN site to Site using the router and ASA

Hello

I have a Cisco 1812 router that is configured for remote access VPN using IPSec (Cisco VPN Client), my question is if I can configure a Cisco ASA 5505 to connect to the router as a VPN from site to site.

Thank you

Karl

Dear Karl,

Yor are right, in this case you can create a tunnel vpn site-to-site between devices or you can configure your ASA as hardware VPN client. That is to say; Easy VPN.

For the same thing, you can consult the document below.

Routing of traffic between two VPN Site-to-Site Tunnels

Hi people,

I am trying to establish routing between two vpn Site-to-Site tunnels which are destined for the same outside the interface of my Cisco ASA.

Please find attached flowchart for the same thing. All used firewalls are Cisco ASA 5520.

Two VPN tunnels between Point A and Point B, Point B and Point C is too much upward. I activated same command to permit security level interface also intra.

How can I activate the LAN subnets traffic behind Point to join LAN subnets behind C Point without having to create a tunnel separated between Point A and Point C

Thank you very much.

Hello

Basically, you will need to NAT0 and VPN rules on each site to allow this traffic.

I think that the configurations should look something like below. Naturally you will already probably a NAT0 configuration and certainly the L2L VPN configuration

Site has

access-list NAT0 note NAT0 rule for SiteA SiteC traffic

access-list allowed NAT0 ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

NAT (inside) 0 access-list NAT0

Note L2L-VPN-CRYPTO-SITEB access-list interesting traffic for SiteA to SiteC

access-list L2L-VPN-CRYPTO-SITEB permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

Where
- NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteA LAN to LAN SiteC traffic must use the VPN L2L existing SiteB
Site B

access list OUTSIDE-NAT0 note NAT0 rule for SiteA SiteC traffic

OUTSIDE-NAT0 allowed 192.168.1.0 ip access list 255.255.255.0 192.168.3.0 255.255.255.0

NAT (outside) 0-list of access OUTSIDE-NAT0

Note L2L-VPN-CRYPTO-SITEA access-list traffic for SiteA to SiteC through a Tunnel between A - B

access-list L2L-VPN-CRYPTO-SITEA ip 192.168.3.0 allow 255.255.255.0 192.168.1.0 255.255.255.0

Note L2L-VPN-CRYPTO-SITEC access-list traffic for SiteA to SiteC through a Tunnel between B - C

access-list L2L-VPN-CRYPTO-SITEC permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

Where
- OUTSIDE-NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic. It is this time tied to the 'outer' interface, as traffic will be coming in and out through this interface to SiteB
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEA (and SITEC) = are the ACL in the configurations of VPN L2L that defines the SiteA LAN to LAN SiteC traffic should use existing VPN L2L connections.
Site C

access-list NAT0 note NAT0 rule for SiteC SiteA traffic

NAT0 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0

NAT (inside) 0 access-list NAT0

Note list-access-L2L-VPN-CRYPTO-SITEB SiteC to SiteA interesting traffic

L2L-VPN-CRYPTO-SITEB 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0

Where
- NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteC to SiteA NAT traffic
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteC LAN to LAN SiteA traffic must use the VPN L2L existing SiteB
To my knowledge, the foregoing must manage the selection NAT0 and traffic for VPN L2L connections. Naturally, the Interface/ACL names may be different depending on your current configuration.

Hope this helps

IPSec VPN Site-to-Site router Cisco 837 to Firewall FortiGate 200 has

I had a challege for a site to site vpn scenario that may need some brainstorming you guys.

So far, I have had a prior configuration planned for this scenario, but I'm not very sure if the tunnel I created will work because I did not test it before with this scenario. I'll go next week on this project and hopefully get a solution of brainstorming you guys. Thanks in advance!

Hello

Three changes required in this configuration.

(1) change the NAT-list access 102 as below:

access-list 102 deny ip 10.20.20.0 0.0.0.255 172.20.10.0 0.0.0.255

access-list 102 permit ip 10.20.20.0 0.0.0.255 any

(2) place the card encryption on interface point-to-point ATM.

(3) remote all of a default route.

Thank you

Problem on site to site and between router vpn client series 2,800

Hello

I need a little help.

I have 2 office of connection with a site to site vpn

Each site has a dry - k9 router 800 series.

Each router has actually client ipsec vpn active and all users can connect by using the client vpn with no problems.

I added the lines for the vpn site to another, but the tunnel is still down.

Thanks in advance for any help :)

the site at the other tunnel is mounted, but it does not pass traffic; What is the source and destination ip on the router that you are trying to ping the address

whenever you try to open the traffic from router A to router B, you must to the source of the traffic.

for ex,.

Router A-->10.1.1.1--fa0/0

Router B - 172.168.1.100

source of ping 172.168.1.100 router # 10.1.1.1

After doing the pings, send the output of the show counterpart of its crypto ipsec at both ends

[VPN site to Site] Are route explicit LAN remote necessary?

Hello

I have configured the VPN Site to be used inside the interface of the ASA (9.4.1)

site2site_inside.jpg
1. The computer in the Zone 1 (192.168.1.1), I can access the Intranet all and it works without a problem--> all traffic through the VPN.
For example, I can use 10.0.0.1 on remote desktop.

2. in the other direction, 10.0.0.1, I try to use the remote desktop on 192.168.1.1, the traffic is not routed over the VPN.

Journal: ' build incoming TCP connections to inside:10.0.0.1/1539 outdoors: 192.168.1.1/3389.

In case 1 (when it worked), he says "build the incoming TCP connection for inside:192.168.1.1/2039 to inside:10.0.0.1/3389.

To fix it, I had to add specific route on ASA: 192.168.1.0/24 inside

It works on both directions.

Is this a normal behavior?

I thought that cryptomap and IPSec SPI would be sufficient.

Thank you

Patrick

Yes, because the cryptomap is mapped to the output interface. The research of the way occurs before you hit the cryptomap. The opposite lane works because you already have a connection (in which are defined interfaces to use).

If your HQ has a (rare) dynamic IP address, you must do 3 things:

1. set up a dynamic DNS host name for your HQ VPN peer (dyndns.org, etc..)

2. your counterpart dynamic crypto map using "dynamic peer hqddns.company.com defined".

3. your isakmp for the peer key a wildcard character ("crypto isakmp key addr 0.0.0.0")

If you say that it is an IP change single opposite HQ, then maybe:

1 Add the new IP address to your 'access-list 101' ACL (remember to use a name instead of ACL numbered for readability)

2. Add another encryption with the new IP address isakmp key

3. Add the new IP address as secondary peer:

map BranchMap 10 ipsec-isakmp crypto
the default peer 22.22.22.22
defined peer 3.3.3.3

IPsec VPN site to site between router problem Cisco ASA. Help, please

Hello community,

I'm stuck in configuring VPN site to site between ASA (OS 9.1) and router Cisco IOS (IOS 15, 2 - 4.M4)

Attachment is router configuration and ASA. I also include the router debug output.

It seems that the two parties must isakmp missmatch configuration, but I have already disabled the KeepAlive parameters. I also turn off PFS setting on both sides. But it does not work. I have no idea on this problem.

Please help me. Any help appreciated.

Thank you

I didn't look any further, but this may be a reason:
```
 crypto map mymap 1 ipsec-isakmp dynamic dyn1 
```
The dynamic CM must always be the last sequence in a card encryption:
```
 no crypto map mymap 1 ipsec-isakmp dynamic dyn1 crypto map mymap 65000 ipsec-isakmp dynamic dyn1
```
Try this first, then we can look further.

VPN site-to-site between router 831 & windows 2000

We have a Cisco router 831 in a site and windows 2000 Server as a router to another site. Can we set up a vpn site-to site between these two sites? If so, how? Or point me to the link.

This should get you:

VPN Site to Site not upward Tunel on a router

Hello

First time I try to configure the VPN Site to Site on the two routers X and Y. I use cisco SDM

X router that I have set up on this path http://www.tekkom.dk/mediawiki/images/e/ee/IP_sec_site-to-site_sdm.pdf

Then I create a mirror and spent on router Y I tunel up VPN router Y.

But I have problem with router X. When I try to the top of Tunel, I have two problems:

The peer must be routed through the crypto map interface. The following host is routed through the non-crypto map interface. (1) 79.*. * **. **

(79.* *-it is the WLAN router address Y)

Destination of traffic of the tunnel must be channelled through the crypto map interface. The destination following (s) is routed through non-crypto map interface. (1) 10.*. * **. **

(10.* *. *-is router LAN address Y)

Configuration of routers in the files.

Apologies for the lack of your answer.

You have the same card encryption applied to the physical interface and dialer0 interface. You can try removing it from the dialer0 interface and a new test.

If it does not can try you backwards IE. remove physical and apply to the dialer0 only.

Routing between sites that use the site to site VPN

I'm running 7.2 (1) two 515 who have a VPN site-to-site set up a bit as follows:

subnets of the main site - router main site - PIX1___Public IP's___PIX2 - remote site

The main site router: CAT6506 with engine SUP1A

Subnets listed in motor SUP:

SUB1 VLAN

IP address 180.x.1.x.255.254.0

VLAN SUB2

IP address 180.x.2.x.255.254.0

VLAN SUB3

IP address 180.x.3.x.255.254.0

VLAN SUB4

IP address 180.x.4.x.255.255.240

PIX1 is the subnet SUB4 (180.20.4.2)

Remote site subnet: 192.168.1.0/24

Route the engine by default Overtime toward another router that reached the internet via another public IP subnet.

Any host on SUB4 can reach any host on the remote site as long as the SUB4 host default gateway is the inside int PIX1 (180.20.4.2).

No matter what SUB4 host that uses the 180.20.4.1 address (router) default gateway cannot communicate with a remote host, but can communicate with any host from any subnet of the main site.

All remote hosts can communicate with any host on SUB4, regardless of the gateway of the SUB4 host address.

All remote hosts can communicate with the router on SUB4 main site, but can not reach one of the other interfaces subnet configured on the router.

I've added a static route on the SUP engine:

router IP 192.168.1.0 255.255.255.0 180.20.4.2

That did not help.

The uses of motor SUP EIGRP to learn other subnets main site reached through routers, so I added the remote subnet to that:

Router eigrp 10

redistribute static

network 180.20.0.0

network 192.168.1.0

No Auto-resume

No log-neighbor-changes to eigrp

No chance, no more.

I can't help thinking that I'm missing something very basic.

Any help is really appreciated

Hello

PLS, find the changes that must be made and checked.

PIX remotely:

1. you only need a default route and that you can route your subnets via inside as they are outside, so remove these statements

2.i see Access-group configured to be applied to the external interface for traffic coming from the outside, make sure that all required subnets are allowed.

3. in the access list for the corresponding traffic to cryptomap, I see that one included subnet, pls have all included traffic that must be encrypted (as sub1, sub2..)

Main PIX:

1. in the access list for the corresponding traffic to cryptomap, I see that one included subnet, pls have all included traffic that must be encrypted (as sub1, sub2..)

2. is there an 'access-group outside_access_in' access list present in the pix the corresponding traffic - check - the pls

3. by nat (inside) 0 access-list inside_nat0_outbound, include all your inside subnets that must have access to the remote subnet

L3 switch:

1.I see a default route pointing to your router 3640, so pls add a static route to your remote subnet pointing to Pix

IP route 192.168.1.0 255.255.255.0 x.x.22.2

2. pls check in your L3 switch, wheter the appropriate subnets sub1, sub2 are learned properly via the conifugred Eigrp VLAN respective

for example .sub2 and sub3 learning with leap following 8.2, sub 5 via 30.3

Pls try to understand the topology and make configuration changes and let us know the results

Two links one for VPN Site to Site and another for internet on the same router configuration

Hi all

I have 2 internet links an ADSL and lease terminated on the same router. I need to configure ADSL for VPN site-to-site of HO and internet leased line dedicated for all users.

my site IP subnet is 10.10.100.0/24 and HO subnet is 10.1.0.0/24. Please find attached Config and advice it will be OK and works fine

Thanks in advance...

Mikael

Hello

For me, it looks like it has configured the route correctly;

ip route 0.0.0.0 0.0.0.0 fastethernet4 -> for all traffic to the internet.

Road 10.1.0.0 ip 255.255.255.0 Dialer1 -> for vpn traffic to HO.

The public_IP_HO must be defined according to the map of encryption using the set by the peers command.

I want to add is on the isakmp policy hash attribute, you can choose between sha/md5 or whatever available on your device. Make sure that the isakmp policy to match political isakmp of your HO.

The other thing is the acl for the internet. You may want to consider replacing the deny statement if you want to deny traffic only to your jar currently it is said to deny all traffic 10.10.100.0 10.0.0.0 network, not to the 10.1.0.0 HO (network).

HTH,
