Router Cisco 871 as a VPN server
Hello!
I have a Cisco 871 router which I want to implement a VPN (PPTP) server at home, so that I could connect to it from outside (from an Internet café, for example).
All I need is to be able to use my IP of the home across the world just by connecting to the VPN through PPTP. The router would be the only thing connected to the internet in my house and it is not all of the devices connected to the router. Remote access to my IP is all I need.
The problem is that I have no idea how to do that.
So I would really appreciate if someone could help me with this,
Thank you!

Hello
I try to configure my router ADSL cisco 877 as a vpn server, so that multiple site can connect to the ADSL cisco 877 router. Is it possible to achieve this goal. If yes what is the procedure and if possible, please copy the URL for documentation here.
Thank you
Siva.
Here is the sample configuration for the client in network Extension mode and IOS Easy VPN server:
http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080808395.shtml
The sample configuration uses local authentication, you can always change it to use radius authentication.

router Cisco 871 no internet no access
I am studying and practicing fo my ccnent and I am very new to cisco routers and so far have done well until I tried to access the internet. I have a router 871 which has a switch catalyst 2950 branch above. connected to the switch, is this computer, a router cascading and an external network drive. connected to router cascading is an xbox, ps3 and another computer. on both computers I ping the router and the switch but I can't reach beyond the router to lynksis router that I used to connect to my network. also pingin one computer on the other give me "destination host unreachable".
This is my config running. Thanks to SD for any advice

If you can ping the router on then you should be able to ping from the PC on. Try searching for the source of your ping to the IP Address of the VLAN 1 interface on your router and see if it works.
In addition, you don't need these static routes:
IP route 0.0.0.0 0.0.0.0 71.246.236.11
IP route 0.0.0.0 0.0.0.0 10.1.41.79
Route IP 192.168.0.0 255.255.255.0 192.168.1.1
IP route 192.168.1.0 255.255.255.0 192.168.1.1
IP route 192.168.100.0 255.255.255.0 192.168.100.2If you don't want to show up at static routing, you might be able to get directions to RIP on the Linksys. You must have access to the Linksys however.
At the end of the day, probably you will need to configure NAT on the interface to the Linksys and the VLAN1 interface and then Overload:
Int fa 0/4
IP NAT outsideInt vlan1
IP NAT insideAccess-list 10
Permit 192.168.100.0 0.0.0.255IP nat inside source list 10 interface f 0/4 overload

Help setting up a router Cisco 871 for home...
871
Hello Andrew,.
Alain you provided the entire configuration of what you asked, but I think you also need to configure NAT in order to access internet from PC LAN.
Reason for this is that get you the WAN IP address and default route ISP, for example:
IP: 10.0.0.1
Mask: 255.255.255.0
Gateway: 10.0.0.254
But your ISP guess you connect only a single PC, so only 10.0.0.1 IP address will have access to the internet. ISP will pass all traffic of 192.168.10.0/24 and 192.168.20.0/24 because these networks are unknown to the ISP. You will need to NAT your internal networks to your WAN IP 10.0.0.1.
Here is the configuration:
NAT_ACL extended IP access list
deny ip 192.168.10.0 0.0.0.255 192.168.10.0 0.0.0.255
deny ip 192.168.10.0 0.0.0.255 192.168.20.0 0.0.0.255
deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255
deny ip 192.168.20.0 0.0.0.255 192.168.20.0 0.0.0.255
permit ip 192.168.10.0 0.0.0.255 any
ip licensing 192.168.20.0 0.0.0.255 any
refuse an entire ip
NAT_MAP route map
corresponds to the IP NAT_ACL
IP nat inside source overload map route NAT_MAP interface FastEthernet4
interface Vlan10
IP nat inside
interface Vlan20
IP nat inside
interface FastEthernet4
NAT outside IP
Last thing, it is not necessary, but maybe you want to prevent users of VLANS to access your internal network:
Restrict_GUESTS extended IP access list
deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255
ip licensing 192.168.20.0 0.0.0.255 any
refuse an entire ip
interface Vlan20
IP access-group Restrict_GUESTS in

3030 router Cisco LAN to LAN VPN, can only mount router tunnel
I am unable to raise atunnel from inside my VPN concentrator 3030 (IOS 3.5.2) tunnel 3 uses Ethernet as the side private tunnel. Is there some kind of problem on the VPN 3030 internally that does not use the Ethernet IP source 3? Once triggered on the remote side, the tunnel passes and receives traffic and I can ping devices on the remote side of my private network, but I can't ping any remote device from inside the VPN 3030.
Do you mean that you can now view the tunnel of something related to the 10.255.0.0/24 network, but no ping comes from the VPN3030 itself?
When you ping the VPN3030 it will automatically use the private IP address I think. Debugging isn't warning us whatever it is the first that you attached is where the Diffie-Hellman group was incompatible. If you have passed Phase 1 but, you will see a debug on the router that is similar to the following message:
* 26 Nov 08:51:37.901: IPSEC (validate_proposal_request): part #1 of the proposal
(Eng. msg key.) Local INCOMING = 204.74.161.161, distance = 216.34.168.148,.
local_proxy = 10.1.215.0/255.255.255.0/0/0 (type = 4),
remote_proxy = 10.255.0.0/255.255.255.0/0/0 (type = 4),
Protocol = ESP, transform = esp-3des esp-md5-hmac,
lifedur = 0 and 0kb in
SPI = 0 x 0 (0), id_conn = 0, keysize = 0, flags = 0 x 4
Here you can see that the remote_proxy is 10.255.0.0, which shows that the 3030 uses this network as the source subnet. If you try and ping from the 3030 again run debugging, you will probably see the 172.16.0.0 (the private interface) as the remote_proxy.
Why is it important that you cannot bring up the tunnel within the 3030 anyway? When would you like to do this?

Pass Cisco 871 and VPN to the SBS 2008 Server
to precede the questions below, I'm responsible for COMPUTING internal with several years of site / offsite support. I also have very limited knowledge of the inner workings of a Cisco device. That said, I've beaten my head against a wall, trying to configure my router Cisco 871 to allow access to our internal server of SBS 2008 VPN hosting services. I think I, and properly configured the SBS 2008 Server.
I use advanced IP services, version 12.4 (4) T7

Based on your description, I am assuming that you are trying the traffic PPTP passthrough via the router 871, and the PPTP Protocol ends on your SBS 2008 Server.
If this is the correct assumption, PPTP uses 2 protocols: TCP/1723 and GRE. Your configuration only allow TCP/1723, but not the GRE protocol.
On 101 ACL, you must add "allow accord any any" before the declarations of refusal:
101 extended IP access list
1 allow any one
I guess that the PPTP control connection works fine? Are you able to telnet to the router outside the ip address of the interface on port 1723?

How to Setup Cisco 1841 as a site to site VPN VPN server, with watch guard
I would like to implement a cisco 1841 as a VPN server to establish s IP VPN (site to another) of a watch guard firewall,.
I have looked through some examples of cisco config, but can't seem to get a lot.
Can you please send me sample config steps I need o perform on the cisco router? and what credentials must be awarded to watch keeps establishing a permanent VPN?
emergency assistance will be greatly appreciated.
The cisco router is configured as a lan to lan normal IPSEC tunnel, there is no difference when configuration to create a tunnel to a watchguard/sonicwall or all that peer will use, you can use this link as a guide:
If you have problems make me know.

ASA VPN server and vpn client router 871
Hi all
I have ASA 5510 as simple VPN server and 871 router as simple VPN client. I want to have the user ID and permanent password on 871 and not to re - enter username and password since 871 uses dynamic IP address and every time I have to ' cry ipsec client ezvpn xauth "and type user name and password.
any suggestions would be much appreciated.
Thank you
Alex
Do "crypto ipsec client ezvpn show ' on 871, does say:
...
Save password: refused
...
ezVPN server dictates the client if it can automatically connect with saved password.
Set "enable password storage" under the group policy on the ASA.
Kind regards
Roman

Hello.

I want the 172.18.122.6 host can do ping to the 10.218.10.117 host at the other end of the router, but its does not work, what is the problem with this config? could someone give me a hand?

Installation easy vpn Cisco 871
I have a Cisco 871 router sitting behind my adsl router and I have configured to accept vpn connections from clients from outside (partially configured by cli and partly by SDM).
It works well, in that I can connect my LAN and access my network inside resources, however I can't access the web when connected via vpn.
Is it perhaps to nat? I hope that someone can see why in my config. Thank you.
Hi Chris,
The only reason I understand here, customers lose their ability to achieve internet when connected by VPN is, according to the current configuration, all traffic (including the NetBIOS) runs through the tunnel. So when a package leaves the machine with a source of intellectual property (one of the private ip address of the pool set) of the client and the destination 4.2.2.2 (can be any ip on the internet), there is no translation defined for the ip address of the VPN client on the router.
Thus, package from the computer of the customer with an address NON-Routable cannot access the internet for obivous reasons.
To work around the problem, try this.
access-list 5 by 192.168.1.0 0.0.0.255
(assuming that 192.168.1.0 is that the VPN client subnet have access)
Then,
Crypto home isakmp client configuration group
key xxxx
ACL 5< binding="" the="" acl="">
By creating the acl the binder to the configuration of the client, and 5 am Division of traffic in the tunnel. In other words, only for the 192.168.1.x subnet traffic will pass through the tunnel and rest will take the path of the LOCAL ISP.
I hope this helps...!
Concerning
M.

2651xm (IOS 12.4(9T) VPN server - default route
When my clients connect to the VPN server, their default route prepared to go through the VPN. If they resemble the State of the connection, it shows "0.0.0.0 0.0.0.0" under the secure routes. I want to do so that one class C subnet is in the list. How can I do this?
Thank you!
This is called "split tunneling". For maximum security, you should not use it.
Never done on IOS myself, but this would contribute to the code snippet:
access-list 150 permit ip 30.30.30.0 0.0.0.255 any

Hello
I am trying to create an easy VPN server on Cisco 831. When I "test" the easy VPN he said that it tested successfully, but when I try to VPN in the router of the built in Windows XP VPN client, I'm unable to connect.
Does anyone have recommendations for how to configure easy VPN? I basically just selected all the default options. I was not able to find tutorials in the Cisco online documentation.
Do I need to have the Cisco VPN client to connect to the Cisco router?
Other thoughts?
Your IP address pool you are trying to assign to remote users is part of your local network, which is not the best way to assign the ip address to the VPN Clients, and I've seen a lot of problems in the past were route it not forwards the packets to the client. This allows you to change the POOL of something other than your LAN. E.g. 192.168.1.0/24.
Also, make sure that you re - configure your 102 ACL accordingly.
Once you make changes, try to connect again and let me know how it goes.
Kind regards
Arul

VPN site to Site on both ends using Cisco 871
I would like to configure VPN Site to Site using the Cisco 871 templates at both ends, but a hard time to set it up. Can someone tell me how to do or if you know of a link that may help me set up as soon as possible?
I can learn it, but it's time that banned me in the implementation. The other end is already configured to provide Internet access to all users.
Tom,

Easy vpn server issues of Cisco 800 series.
Hello.
I want to deploy the easy vpn server on cisco 876 and 877 10 routers and access from a remote location (company headquarters). When I leave the firewall of the router off the vpn server works. When I turn it on it doesn't.
Although I allow all traffic to my ip for example 80.76.61.158 I can't access the vpn server.
I tried a place to let the firewall off and it worked fine.
I use SDM to configure the vpn server. Any ideas what I can do with the cause of firewall I really can't leave it "open."
Thanks in advance.
It would be a good idea to paste the configuration of the VPN server to the firewall.
Kind regards
Kamal
