Issue from site to site of SRP527w port forwarding

Hello

I have problem with setting up port forwarding on the VPN between two cisco 527w.

Scenario when we see a tunnel VPN from Site to Site between Site A and B; a printer behind Site B must be accessible using the IP WAN of A Site address.

Like the picture above:

-From site A, I am able to ping printer and printer access locally and via 120.146.x.x with port forwarding to installation on site has to the printer.

-From site B, I am able to ping A site gateway but not able to access the printer through 120.146.x.x. The printer can be access via 129.203.x.x if port forwarding is configured on the site B on the printer.

Cisco SRP 527w supports port forwarding via VPN site-to-site site A to site B printer?

Y at - it no suggest or another solution for this scenario?

Some help would be very appreciated.

Kind regards

Thai

Hi thai,

I'm not entirely sure - I think that an IOS based router, for example, the 800 series, you could do with proper setup.

I would say that remote access to a printer or a server like this is perhaps not the most secure solution however. A better approach would be to use a router that supports both a remote access VPN site. With this, you must be able to use a VPN client to access the site with the IP address static, then tunnel to the other site where the device is. You might consider the series RV of the device as well as IOS routers for that.

Kind regards

Andy

kid or childs is not receaving emails from sites of checking e-mail like facebook or I tunes

I did everything for free account so that I can check his accounts on Facebook and Itunes does not receive emails from sites and also do not have a junk folder and it will not let me. Any suggestions would be helpful, it's a hotmail account.

Hello

By default, the junk mail folder is not available if the parent account is one that maintains a list of contacts of the child. To activate the junk e-mail folder, the child's account must be defined to manage their contacts. Please follow these steps:

1. connect to https://fss.live.com using your Parent account.
2. click on change settings under the user name of your child.
3. Select Contact Management on the Panel of the menu on the left.
4. in respect of the management on behalf of the child of the contacts, select the child manages their own contact list.
5. click on Save.

These steps will also address the issue with do not receive emails from these sites. Because when your child maintains a list of contacts, they will be able to receive emails from people/websites that aren't on the list of contacts.

Note: Access to this feature has been removed for users who have not already configured it. If you had introduced on the market before, you will still see the feature on the site of family safety on the left side of the Web page for contact management. For more information about this, please read the article in the link below:

Where is the function of the safety Contact family management?

VPN site to Site with an ASA behind Port Forwarding device

Hi, I want to configure a VPN from Site to site with an ASA with a public static IP adress and other ASA located behind a device with a public IP address that can forward ports to the ASA.

I have found no documentation for this configuration in the Cisco KB, anyone have a link for me or a brief description of the requirements?

Thank you

Tobias

Hello

Take a look at this documentation

VPN clients hairpining through a tunnel from site to site

I have a 8.2 (5) ASA 5510 in Site1 and a 8.2 (1) ASA 5505 Site2 they are configured with a tunnel from site to site.

Each site has VPN clients that connect and I would like to allow customers to access on both sides across the site-to-site tunnel servers.

I enabled same-security-traffic permit intra-interface I also added the remote networks to access list who made the split tunneling.

I think I'm doing something wrong with nat, but I don't know, any help would be greatly appreciated.

Hello

The output seems to say that traffic is indeed transmitted to connect VPN L2L

Can you PING from hosts on the network 172.18.2.0/24 to the hosts on the network 172.17.2.0/24?

Have you tried several different target hosts on the network you are trying to ping while might exclude us actual devices are not just meeting the specifications these PINGs?

No Ping response from Site to Site connection between 876 of Cisco and CheckPoint Firewall

Hello!

We try to create a Site-to-Site - connection IPSec between a Cisco 876 (local site) and a control-firewall station (remote site). Cisco 876 is not directly connected to the internet, but it is behind a router ADSL with port-forwarding, redirection of ports 500 and 4500. The configuration of the Cisco 876 running is attached to this thread. Unfortunately, I get no results when debugging the connection with the command "debug crypto isakmp" and "debug crypto ipsec".

From the point of view of Checkpoint firewall the connection seems to be implemented, but there is no response from ping.

The server in the local site to be achieved since the network behind the firewall Checkpoint has a routing entry "PEI route add [inside the ip-net Remote] 255.255.255.0 [inside the premises of intellectual property]" (see also annex current config name ip addresses).

Establishing a VPN Cisco Client connection to the same router Cisco 876 works very well.

Any help would be much appreciated!

Jakob J. Blaette

Hi Jakob,

Add my two cents here.

You should always verify that the following ports and Protocol are open:

1 - UDP port 500--> ISAKMP

2 - UDP port 4500--> NAT - T

3-protocol 50---> ESP

A LAN-to-LAN tunnel will never establish a TCP session, but it could use NAT - T (if behind a NAT). Remember that a single translation isn't a port forwarding, a LAN-to-LAN tunnel is not good unless you have a one-to-one translation of the NATted device, which I think, in your case the router is working.

HTH.

Permit for site to Site VPN - display Ports

Hello

I have HQ(Site A) ASA5505 configuration with two VPN Tunnels established to the remote sites (Site B and) C Site. Everything works very well. I am able to ping on each subnet devices (from Site A to Site B and Site C and vice versa) successfully; However, cann't devices communicate with a server at Headquarters (Site A) and I wanted to make sure that the ports are open in the Tunnels. How to accomplish this?

Much appreciated!

Best, ~ sK

Hello

There are many things that decide what traffic is transferred to the L2L VPN connections and what is allowed through the actual firewalls.

First of all, you naturally want to confirm that the host which need to communicate is really configured on the VPN L2L configurations. In the ACL, which defines the traffic.

If this mentioned that ACL is very though then you will probably want to take a look at the NAT configuration are ok. You use NAT0 to all traffic on all of these VPN L2L connections?

Then, you naturally want to confirm that host generate connections that are allowed to form the connection via the 'inside' ACL on the ASA local interface.

Then theres a "sysopt connection permit-vpn. This configuration command controls the adjustment if connections through VPN connections are allowed to ignore the 'outer' interface ACL. The default setting for ASA, is that all connections from VPN connection are automatically bypassing the 'outside' the ACL interface (or rather the ACL of the interface when the VPN was interrupted on the SAA, although its 99% of the time 'outside')

To check the State of the above mentioned questioning the command 'show sysopt run '. If you do not see what is the "vpn" in the output, then you will know the setting is in its default value and therefore is not block connections. If there is "no sysopt connection permit-vpn" means that you need to allow all necessary traffic while the 'outer' interface ACL.

To check if certain traffic gets correctly transmitted to the VPN L2L at his LOCAL ASA then you can use the command "packet - trace.

Format would be
- Assuming the traffic is initiated by behind the interface 'inside '.
entrance to Packet-trace inside tcp

This example displays a message about long'ish on the CLI that will tell all the audit which are made to the traffic that you are trying to simulate. It will also inform your NAT and ACLs rules is corresponding to the movement. He will also mention if traffic is transferred to a VPN connection.

Natutally firewall logs is a great tool to determine where the traffic stops (checking all the ASAs related to the connection attempt). The ASDM GUI (monitor section) is ideal for this purpose.

Also if you want to go even deeper, you can capture packets from the firewall to the ASA. But since in this case we are talking about VPN/encrypted traffic you can only take the capture on the interface of 'inside' interface input/output traffic is not encrypted.

I do not think that the ASA provides a tool to tell you what traffic is allowed through the L2L VPN connection. You can use combined the above to determine that. Of course, you might be able to run a program on a host behind the ASA to scan open ports.

I hope that some of this information will help you understand what is wrong.

Of course, ask if you need more information about something that I mentioned above. If you take the exit "packet - trace" of some of the ASAs, you can share the result here for us to look through.

EDIT: typos

Edit2: Even the strangest faults strike. I'm too tired.

Tunnel VPN remote Internet and VPN remote VPN from Site to Site traffic?

Hello

We try to remote traffic from our users VPN tunnel through our ASA 5510 as well as to allow the only access for remote user VPN traffic to the other end of the all our VPN site-to-site connected to the same ASA. Basically, we who want to VPN in the network in order to access all of our networks business. We try to get away with this without using split Tunneling.

I can currently get internal traffic from the remote user VPN to reach all other vpn site-to-site tunnels without the internet in tunnel. The problem is when I add the following statement to the NAT:

NAT (outside) 1 10.10.19.0 255.255.255.0 * 10.10.19.0 is the address of the remote VPN Client

Internet traffic to the remote VPN starts to get in the tunnel, but I lose the opportunity to reach one of the other tunnels from site to site by the remote VPN tunnel.

I also begin to receive the following errors in the journal of the ASA

3 July 1, 2009 12:34:18 305005 10.10.19.255 137 no group of translation not found for udp src outside:10.10.19.3/137 dst outside:10.10.19.255/137

Any help with how NAT statements must be defined for this work would be appreciated.

Thank you

Concerning

VoIP QoS for Tunnel from Site to Site

Hi all

I need help to configure QoS for VoIP between two Cisco ASA 5505 with VPN Site to Site.

There is no need for bandwidth reservation, only 46 (EF) DSCP should be higher and DSCP 26 second queue higher and rules apply only to a site to site VPN.

Usually, I try to configure the ASAs via ASDM and discovered in the documentation Cisco how configure QoS DSCP bits with a Service policy and how to configure QoS for a VPN from Site to Site (rule Service-> Match traffic strategy). But how to configure QoS for a bit DSCP applies to Tunnel from Site to Site? And how configure different priorities for both DSCP bits, this is defined by the order of political Service?

The quality of service must be activated on the two ASAs to inside interface?

Thanks in advance

Tobias

Remote VPN users cannot access tunnel from site to site

Cisco ASA5505.

I have a tunnel of site-to-site set up from our office to our Amazon AWS VPC. I'm not a network engineer and have spent way too much time just to get to this point.

It works very well since within the office, but users remote VPN can not access the tunnel from site to site. All other remote access looks very good.

The current configuration is here: https://gist.github.com/pmac72/f483ea8c7c8c8c254626

Any help or advice would be greatly appreciated. It is probably super simple for someone who knows what they're doing to see the question.

Hi Paul.

```
  
```

card crypto outside_map 1 set pfs

peer set card crypto outside_map 1 AWS_TUNNEL_1_IP AWS_TUNNEL_2_IP

card crypto outside_map 1 set of transformation transformation-amzn

I recommend you to use a local IP address pool with a different IP address that deals with the inside interface uses, now you are missing NAT are removed from the IP local pool to the destination of the site to site:

NAT_EXEMPT list of ip 10.0.0.0 access allow 255.255.255.0 172.17.0.0 255.255.0.0

NAT (outside) 0-list of access NAT_EXEMPT

Now, there's a dynamically a NAT exempt allowing traffic to go out and are not translated.

I would like to know how it works!

Please don't forget to rate and score as correct the helpful post!

Kind regards

David Castro,

Difficult to complete phase 1 of the tunnel from site to site.

I have a 1921 Cisco (config) and between an ASA 5505 (config) that I am trying to establish a tunnel from site to site.

I think I should be able to see the tunnel when I type isakmp crypto to show its, but it is not at all.

Cisco 1921 outside intellectual property:
ASA 5505 outside intellectual property:

I tried to ping from the inside network to the ASA, inside network on 1921. It is not bring up the tunnel.

How is the tunnel is not complete the phase 1?

Can you please send the information about the configuration? Crypto maps, ACL, etc.

VPN from Site to Site and easy 871W

I have a problem with the configuration of Site to site and easy both together on the same router 871W

Something is working, but not everything.

x.x.x.x - address IP WAN
a.a.a.a - gw for WAN IP address
z.z.z.z - IP address of the VPN Site-to Site
192.168.201.0/25 - LAN
192.168.200.0/24 - easy VPN address
192.168.151.0/24 - Site-Site LAN

Site-to-site work properly, everythings fine, but no easy VPN.

Configuration of Cisco VPN Client:

Home - x.x.x.x, group auth name - RemoteGroup, pass *.
user test, pass *.

I have a successful connection of Cisco VPN Client (I see a closed lock - connected status)

Connection gave me the address 192.168.200.5.

But I can't see LAN or LAN from Site to Site.

And I don't have any idea what may be wrong.

could someone please give me some direction, I have a set of vpn clients set up on a pix and I'm trying to give them access to a network that is connected via a link from a site that is set up on the same pix. so, basically, that it receives information from VPN client on the same interface, it built the tunnel from site to site, I've heard that's not possible is that the case. Or it can be fixed, I can provide diagrams and if necessary conf files.

You are right. You need a minimum of 7.0 for the feature you're looking for.

Kind regards

How can I block a VPN from site to Site traffic

I configured a VPN from Site to Site, the wizard on a

ASA 5510 and it works.

However, I want to restrict http traffic only.

I tried to change the ACL entry that allows ip traffic to allow only http traffic, but that seems to block all traffic and translates into a journal entry:

Inbound TCP connection doesn't deny x to Y/80 SYN flags on the incoming interface.

I managed to block pings by entering an ACL rule to specifically deny icmp, but I would like to deny all except http.

Any advice on how to achieve this appreciated.

William.

Hello

Guess that's what you're looking for. See the Bidirectional VPN filter configuration section.
